Safety guidelines
Prior to and during the performance of tests, adjustments and repairs, the following safety guidelines must
be followed:
Any type of work may only be performed by qualified trained personnel or under the supervision and
responsibility of such personnel.
Qualified trained personnel are persons, who – based on specialized training and experience – have
sufficient knowledge in the general area of earthmoving machinery and the specific technology of our
machines. They must also have knowledge of all applicable laws and general work protection
regulations, guidelines and generally approved rules concerning technology and be able to evaluate if
earthmoving equipment is safe to operate and if the necessary work can be performed without
endangering themselves or third persons.
Never operate a machine with a raised cab/ operator’s platform! The machine may only be operated
with a lowered and secured cab / operator’s platform!
Always adhere to the adjustment values noted in LIEBHERR documentation when performing
adjustment work.
When delivering the machine, the operating personnel must be trained using the currently valid
operating manual. The safety guidelines in that manual must be particularly observed.
These safety guidelines must also be observed when performing testing, adjustment or repair work.
However, there are special repair and/ or inspection tasks, which require different procedures than
specified in the safety guidelines. In such cases, qualified personnel or individuals performing the work
under the supervision of such personnel should assure that additional safety precautions necessary to
insure the safety of those involved in the repair and/ or third parties are taken. The decision to carry out
this measures can only be made by qualified expert personnel. Such examples of repair and/ or
maintenance include, but are not limited to the following:
- Opening of the side engine compartment doors with the Diesel engine running to carry out tests and / or
adjustments.
In these cases, it should be assured that the side doors are properly secured for the complete duration
of the work to prevent them from closing unexpectedly and / or inadvertently. Avoid body contact with
turning and / or heated parts! Wear only tight clothing (for example no scarves, no ties, no wide sleeves,
etc.)
- Starting the Diesel engine with the cab tilted, as well as actuating the travel drive with properly raised
machine for adjustment, repair and diagnostics purposes. In these cases, before starting the engine, it
must be ensured that the cab support as well as the support under the machine and the required ground
clearance of the track chains has been checked.

Service Items
Notes for the disposition of service fluids and filter:
- Service fluids may not be discharged into the ground, drainage system or waterways.
- Different service fluids and filters should be collected and disposed of in separate containers.
- Do not use containers, which previously held food items or drinks - to prevent danger of mix-ups.
- Dispose of these items in an environmentally friendly manner according to applicable guidelines and
regulations. Observe all state, local and national regulations.
- Do not use old or incorrectly stored service fluids and filters, dispose of them properly.
1. Service fluids for Diesel engines with turbo chargers
1.1. Engine lube oil
Engine lube oils must meet a certain quality and a certain viscosity, depending on their use and ambient
temperatures. Problem-free operation can only be ensured only if the requirements for both areas are met.
1.1.1 Oil quality
To meet the technical demands, only highly alloyed lube oils are used in modern Diesel engines. They
consists of high-quality base oils, mixed with additives. These additives provide the required properties for
these oils.
For LIEBHERR Diesel engines with turbo chargers, oils of the following specifications are approved, the higher
quality oils are preferred:
API - classification : CF-4, CG-4, CH-4, CI-4,
(American Petroleum Institute)
ACEA (CCMC) - classification : E2 (D4), E3 (D5), E4, E5
(Association des Constructeurs Européens de l´Automobile)
Note: For older machines / Diesel engines, if still in use, engine oils according to the lower specification as
noted in the original operation manuals may be used. However, we recommend the use of these new
oils, since the service life of the engine can be extended significantly by using these higher quality
oils. The originally noted oil and filter change intervals may be extended.
1.1.2 Oil viscosity
Z In addition to the quality, the oil must also provide a certain viscosity the selection is made according to the
SAE - classification (Society of Automotive Engineers).
The determining factor for the correct selection of the SAE classification is the ambient temperature. In most
regions, SAE 10W-40 is recommended (see chart below).
If the viscosity is too high, starting problems can occur, if it is too low, the lubrication efficiency can be
endangered, both factors can lead to increased engine wear.
The temperature ranges shown in the following chart are guidelines and may be exceeded or fallen below for a
short time.
For the operation in extreme climate zones, such as in arctic regions, special guidelines apply and are
available from the manufacturer.

1.1.3 Oil change intervals
The oil change intervals noted in the Maintenance and Inspection schedules always apply to "normal operating
conditions". They apply for normal, central European temperatures, annual operation of approx. 1000
operating hours, use of oils of the required minimum quality and fuels with a sulfur content of less than 0.5%.
When using higher quality oils, the operating hours per interval may be doubled - see the following chart.
However, the 500 hour interval may not be exceeded.
Engine oil and filters must be changed at least once a year, even if the given change interval has not yet been
reached.
In difficult circumstances, such as repeated cold start, higher sulfur content (above 05.%) in the fuel, more
severe climatic conditions (for example continuous temperatures below -10°C) etc., the intervals must be cut in
half. This means, for each difficulty, the permitted operating hours per interval must be multiplied by a factor of
0.5.
Permissible oil change intervals in operating hours:

to 0,5% 125 hrs. 250 hrs.below -10°C
Continuous
temperature above 0,5% 60 hrs. 125 hrs.
1.2. Diesel fuels
Diesel fuels must meet the minimum requirements of the following specifications.
The sulfur content may not exceed 0.5%. A higher sulfur content has negative effects on oil change intervals
and engine service life. A higher sulfur content above 1% is not permitted.
Fuels with low sulfur content (for example, according to European regulations <0.05 %) must contain additives
to retain the lubrication efficiency according to HFRR(60°)-Test <400 m - . Insufficient lubrication causes
premature wear of the injection system components, especially distributor injection pumps. The additives should
be added by the fuel supplier, as he is responsible for the quality of the fuel. We do not recommend addition of
secondary lubrication additives by the user.
Approved fuel specifications:
DIN EN 590 + HFRR(60°)-Test <400 m
ASTM D 975 - 89a 1D and 2D + HFRR(60°)-Test <400 m + cetane rating >45 (recommendation: >50)

Diesel fuels in very low temperatures
At ambient temperatures below freezing (0 C), the flow properties of warm temperature Diesel fuel can become
insufficient due to paraffin excretion. The same applies to cold temperature Diesel fuels in temperatures below.
-15 C.
In order to prevent operating problems in even lower temperatures, Diesel fuel with an additive is sometimes
available, for use in temperatures to -20 C.
In order to prevent operating problems in even lower temperatures, mix Diesel fuel with normal gasoline or
petroleum. Addition of normal gasoline is a makeshift measure and may not exceed 30% per volume. Do not
use Super gasoline for mixing.
Mixing fuel can diminish engine performance, for that reason, keep the added fuel as low as possible,
depending on the ambient temperatures.
For safety reasons, mix fuel only in the fuel tank. When refueling, add the lighter additive before the Diesel fuel.
Then let the engine run for a short time until the mixture has been distributed throughout the fuel system.

* = If an addition of more than 50% is required, use only petroleum (no regular gasoline). The Diesel fuel part
may never be more than 50% .
Additives to Diesel fuel (flow improvers)
Commercially available flow improvers can also improve Diesel fuel properties in cold temperatures. Always
read and observe the manufacturers user guidelines and quantities.
1.3. Coolant
Coolants, containing unsuitable anti corrosion / antifreeze fluids or wrong mixed coolants could damage the
engine or its parts, caused by cavitation or corrosion. Additionally heat isolating deposits could be created on
heat transferring parts, which overheat and lead to the damage of the engine.
For a long term, fault free operation, the coolant must be filled year round with a mixture of at least 50%
anticorrosion/antifreeze fluid. This concentration protects the system to approx. -37°C / -34°F.
Note: Do not use more than 60% anti-corrosion / antifreeze fluids, a higher percentage would actually
reduce the cooling and antifreeze protection and causes gel formation in the coolant fluid. Danger of
engine damage!
Protection to
Percentage of antifreeze (%)
Antifreeze protection chart

Coolant filters are used on some engine series, which filter the coolant in the auxiliary flow and in addition, a
chemical additive in the filter (DCA 4) reinforces the protection against cavitation, corrosion, scale deposits and
foam formation. The DCA4 concentration must be between 0.3 and 0.8 units per liter of coolant. See the
following chapter ”Coolant with DCA4”. This results in a mixing ration of approx. 48.5 % water, 48.5 % anti
corrosion /antifreeze fluid and 3 % DCA4.
Check the mixing ratio regularly during maintenance work. See instructions in section 3.4.
If coolant must be replaced, make sure that the given mixing ratios are retained. Do not fall below this ratios nor
exceed it.
Due to the natural aging process of the coolant, it must be replaced at least once every 2 years. Use only
suitable coolant, free of contaminants. Clean contaminated cooling systems. Note the following regulations.
To replace or add coolant in larger quantities, mix the given parts outside the cooling circuit in a suitable, clean
container first.
Fresh water guidelines:
To mix coolant fluid, use clean, clear water, which is not too hard. Often, but not always, regular tap water may
be used.
Seawater, brine, brackish water, or industrial waste water is not suitable.
Approved fresh water quality (as of 2001) for use with anti corrosion / antifreeze fluid -
- without DCA4 - with DCA4
Sum of alkaline earths (water hardness): : 0,6 to 3,6 mmol/l 0,6 to 2,7 mmol/l

Liebherr Anti-Freeze "pret a l'emploi" Id.Nr. 10 005 347 - 20 l bundle LIEBHERR
The given anti corrosion / antifreeze fluids are approved for all Liebherr Diesel engines (with and without coolant
filter / DCA4).
1.3.1 Coolant with DCA4 (DCA = Diesel Coolant Additive)
The additive DCA4 is "used up" during use. The DCA4 concentration in the filter compensates for this loss
accordingly, if there is no loss of coolant and the correct filter is used at the given change interval.
The DCA4 concentration must be between 0.3 and 0.8 units per liter of coolant. To check, refer to the
"Maintenance and inspection guidelines", section 3.4.
For change intervals for filter and coolant, see ”Maintenance and inspection schedule” , section 3.2.
If the cooling system is filled initially or refilled after repairs, then DCA 4 in liquid form must be added to the
50% anticorrosion / antifreeze and 50% water mixture. The mixture should be mixed outside the cooling
system. Note the safety guidelines issued by the additive manufacturer.

This results in a coolant mixture ration of approx. 48.5 % water, 48.5 % anticorrosion / antifreeze fluid and 3%
DCA4.
In addition, use a new coolant filter, according to the filling quantity. The correct Id. No. of the filter can be
found in the Parts Manual or the Operation and Maintenance manual of the machine.

Liebherr coolant (ready to use, 20 liter, above mixing ratio) - Id. No. 10 005 347
1.3.2 Coolant - special filling - with anti corrosion fluids, without antifreeze fluids
In exceptional cases and if ambient temperatures are constantly above the freezing point, for example in
tropical regional, where no anticorrosion / antifreeze fluids is proofed available, fresh water and water-soluble
anticorrosion fluids (Inhibitors) may be used as coolant.
Do not use coolant refiners (anticorrosion oils) with emulsifying capacity. If necessary, flush the cooling system
before refilling.
The fresh water quality must meet use with DCA4 - see chart ”Approved fresh water quality”.
The coolant must be changed once a year.
Use of DCA4
To provide sufficient protection against corrosion, approximately twice the amount of DCA4 must be used as
compared to the above mixing ration, when using anticorrosion / antifreeze fluids and DCA4 - see above
"overview chart and filter requirements".
The DCA4 concentration must be between 0.6 and 1.06 units. It must be checked during maintenance work or
when the coolant filter is changed, and corrected, as necessary.
This results in a mixing ratio of
max. 94 % fresh water and
min. 6 % DCA4 additive
Use of products from Caltex / Chevron Texaco / Havoline / Total
To provide sufficient protection against corrosion with these products, a mixture of 92,5 vol.% coolant and 7,5
vol.% anti corrosion fluid must be kept.
The mixture ratio must be checked during maintenance work and corrected, as necessary. The concentration
of the anti corrosion fluid must not fall below 5 vol.% nor exceed 10 vol.%.

2. Oil for hydraulic system
In the hydraulic system, use only Diesel engine lube oils or special approved oils.
2.1. Oil quality
2.1.1 Approved engine oil classifications
API - classification : CF-4, CG-4, CH-4, CI-4,
(American Petroleum Institute)
ACEA (CCMC) - classification : E2 (D4), E3 (D5), E4, E5,
(Association des Constructeurs Européens de l´Automobile)
Note: The API classifications CC, CD, CE and CF are now obsolete, however, in quality, they had been
approved for use in the hydraulic system.
2.1.2 Special oils
Approval is given for each machine type separately. Special guidelines are issued with the release.
The following product presently considered to be an environmentally friendly hydraulic fluid:
Panolin - HLP Synth - VG 46
2.2. Oil viscosity
In addition to the quality, the oil must also provide a certain viscosity, the selection is made according to the
SAE classification (Society of Automotive Engineers).
The determining factor for the correct selection of SAE classification is the ambient temperature, single grade
oils are preferred.
If the viscosity is too high, it can cause cavitations, if it is too low, the lubrication efficiency may be endangered.
Both can cause failure of hydraulic components.
The temperature ranges shown in the following chart are guidelines. When operating the machine within the
black temperature range, the following warm up procedure should be carried out.
Viscosity for environmentally friendly hydraulic fluids according to ISO: VG 46
(covers SAE 10W and SAE 20W-20 or SAE 10W-30)
For operation in extreme climate zones, such as arctic regions, special guidelines are available from the
manufacturer.
Warm up procedure:
a) In temperatures up to 10° C below the given limit (black range)
After starting, run the Diesel engine at medium speed. Warm up the hydraulic system by carefully actuating
the hydraulic cylinders. Extend and retract the hydraulic cylinders fully for short periods. After 5 minutes,
carefully engage the travel hydraulic as well. Total warm up period is approximately 10 minutes.
b) At even lower temperatures:
Before starting the Diesel engine, preheat the oil in the hydraulic tank, then proceed as described in paragraph
a).
Single grade oils
Multi grade oils

3. Gear oil
The lube oil specification for gears is based on API and SAE classification. The oil chamber in travel gears for
double lifetime seal is filled with oil from the hydraulic system - see section 2.
3.1. Oil quality
As a general rule, only oils meeting API - classification GL-5 may be used.
3.2. Oil viscosity
The following oils must be used in travel gears, and are highly recommended for use in splitter boxes:
Viscosity classification SAE 85 W - 140 EP
For splitter boxes, oils of Viscosity classification SAE 90 EP or SAE 80 W - 90 EP may also be used.
For the operation in extreme climatic conditions, such as in arctic regions or in extreme temperatures ranges, such
as in slag applications, special oils may be approved if the prevailing ambient temperatures are known operations.
3.3. Lube oil for final drive - sealing chamber
For oil quality and viscosity see section 2, Oil for hydraulic system, but do not use special oils.
4. Lube oil for support shaft bearing
For oil quality and viscosity see section 2, Oil for hydraulic system, but do not use special oils.
5. Hoist gear oil - pipe layers
As a general rule, the guidelines noted in the Operation and Maintenance manual and the winch manufacturer
should be observed.
For lubrication technical reasons, we recommend the use of Diesel lube oil, which meets at least one of the
following quality and viscosity classifications.
5.1. Oil quality
according to API - classification : CF, CF-4, CG-4, CH-4, CI-4,
ACEA (CCMC) - classification : E2 (D4), E3 (D5), E4, E5,
5.2. Oil viscosity
according to SAE - classification : 10W
ISO - classification : VG 32
6. Grease
6.1. General lubrication points and track tensioner
The grease must meet specification KP 2 k - consistency 2 according to NL GI - class and DIN 51818 and DIN
51825 or EP 2 according to NF-T-60 132 .
The grease must also be lithium based, with a VKA value of at least 2300 N according to DIN 51350 or ASTM D
2596.
6.2. Long term grease / grease to protect against corrosion
For the lifetime lubrication of bearing points of lift cylinder suspensions and to protect against corrosion at the
initial installation of dry bearing points, to protect exposed piston rods, to prevent rust formation, etc., a special
calcic, acid free grease should be used.
We recommend LIEBHERR's special paste CTK - Id. No. 8613 313 01
For general conservation - see section 19, Conservation guidelines - other acid free anticorrosion grease may
be used.
7. Miscellaneous
Always observe all guidelines issued in the Operation and Maintenance manuals, repair manuals and on
drawings.
7.1. Rubber seals on doors and covers
Use silicon spray or Talcum powder.
7.2. Hydraulic cylinder installation
Lubricant for threads of pistons, piston nuts and piston rod bearings -
Liebherr High performance lubricant Id. No. 8300 004

Repair welding
Before starting any welding work on PR Series 4 machines, various electronic parts and components must be
unplugged to prevent damage to the machine.
Note!
See operating instructions: Preparations for maintenance
In addition, for arc welding, the ground terminal of the welding unit should be connected in the immediate vicinity of
the blank work piece, which is to be welded.
1. Preparation of a crack
The crack must be free of paint, grease and dirt.
To prevent the crack from extending during the preparation or the welding process, the end of the cracks should
be drilled with a hole of at least 0.32" (8mm) in diameter.
The crack should now be ground, chiseled, torch cut or arced out at a 60° angle. Be certain the edges are clean
and extend through the full cross section of the material, without exceeding the 0.04" (1 mm) space in the lower
part. On larger grooves, a welding safety should be installed.
Certain materials must be preheated to 300°F (150°C) prior to welding.
Special preparations are necessary when preparing a crack in manganese steel. Due to its hardness,
mechanical preparation, such as a chisel or hobbing machine is not possible. We suggest that the crack is
prepared with a slow running and water cooled grinding wheel to prevent overheating.
Other possibilities for preparing cracks or removing high alloy welding seams are the use of cutting electrodes of
the type UTP 82 AS.
2. Preparation of a weld
The area to be welded must be free of paint, grease, oil, moisture and dirt. During rain, the area to be welded
must be covered. Materials with a thickness above 0.60" (15 mm), high carbon steel or steel which is difficult to
weld, the material must be preheated to approximately 176°- 392°F (80°- 200°C).
Pre-heating is also necessary when the ambient or component temperature is below 40°F (5°C) or when the
construction of the component prevent the welding stress to be released.
3. Storing Electrodes
Use only dry and undamaged electrodes. Electrodes which are rusty or damaged should not be used. Electrodes
should be stored in a dry room with a minimum temperature of 59°F (15°C). Open packages should be carefully
closed and stored after the welding work is completed.

4. Welding Technique
The welding of material with the necessary electrodes (see table under paragraph 7) is in accordance with DIN
1912.
The adjustment of the welding machine - dictated by the different thicknesses of the electrodes - can be taken
from the table of the electrode package.
Beginning with a material thickness of 1/4" (8 mm), butt welds must be made in several layers. The weld is
applied in several beads. Wide butt welds are filled with several side by side beads, with the last layer covering
the center. The electrode should melt evenly without creating burrs and peaks. The valley or crater, which is
created when changing electrodes must be filled in and overlapped with the next electrode. To prevent cracks in
those craters, care must betaken that they are properly filled.
If the crack extends towards the outer edge of the material, slag may be trapped or burn holes may be created.
To prevent this, the following aid may be used: Tack a piece of sheet metal to the outer edge of the material. The
welding seam begins now at the sheet metal in the direction of the arrow. After the welding is completed, the
sheet metal is removed and the edge of the material is ground smooth.
The weld must cool off slowly and should therefore be protected from rain and wind.
5. Reinforcement of the welding seam
If the crack of the material is due to an overload or abuse, a reinforcement plate should be welded over the
crack. The selection of the correct reinforcement plate is based on the construction and load factors of the
component to be repaired.
For this reason, only general recommendations can be made as to the size and shape of the reinforcement
plates.
6. General application of reinforcement plates
6.1. Shape of reinforcement plates
The crossover or connection between the reinforced and not reinforced part should be as gradual as possible.
This means that the size of the plate should be selected in such a way that new or unacceptable high stress in
the repaired parts are avoided. Plates with sharp corners (such as a rectangular plate) should not be used.
Suitable reinforcement plate with Suitable reinforcement plate against
high tensile strength. bending and alternating loads.

Feuille 2.2.01.02
6.2. Plate Thickness
The thickness of the reinforcement plate should be up to 2/3 (66%) of the thickness of the material to be
reinforced.
6.3. Plate Quality
The yield and tensile strength of the reinforcement plate should be equal to the material to be reinforced.
6.4. Plate Installation
The welded area of the crack should be ground so it is smooth and level.
The size of the plate must be selected in such a way that the longer sides of the plate extend into the
connecting construction of the material to be reinforced. The plate should also overlap the crack on each side
by at least 1" (20 mm). The correct position and fit of the reinforcement plate is achieved through clamping and
spot welding.
6.5. Plate Welding
The reinforcement plate should be welded on by running a welding bead alternately on both sides. The welding
should always start in the middle of the plate and run towards the outside. Be certain to observe that each
welding seam has proper run out.
Direction of weld Direction of weld
The size of the welding run "a" is figured out in reference to the thickness "k" of the reinforcement plate.
Use formula: a=0,5 k
Up to a welding run "a" of approx. 1/8" (3 mm) a single run can be made, however, as a general rule, a double
run should be preferred.
Above a welding run "a" of 1/8"(3 mm), the first run provides excellent penetration between the reinforcement
plate and the basic material. Subsequent runs are added on top of the first run.
After the welding is completed, clean the welding seam as necessary. Grind the run out between reinforcement
plate and basic material.

7. Selecting the correct electrodes
For repair welding, only lime based {Kb} electrodes should be used, and as a rule, the electrodes {additional
material} should be "softer" than the basic material. Exceptions to this rule should be observed.
Important: To reach the theoretical welding quality, the work must not only be performed in a
professional manner, the electrode manufacturer's guidelines must absolutely be observed as
well.
Welding of vertical-down welds on steel components is not permissible!

1. Installation instructions
1.1. Slipring seals
1.1.1 Design and Function
Due to the pretension of the O-rings 2, the two duo cone seals (sliprings) 3 are pressed together and therefore
seal of the bearing point via the gliding surface 4.
Seal variations:
- Seal toward the outside - Seal toward the inside
1 Seal mount
2 O-ring
3 Slipring
4 Gliding surface
Note!
Only seals toward the outside are used in the machines of Series 4, because of design
reasons.
1.1.2 Installation
1.1.2.1. General installation notes
The sliprings of the seals are manufactured as pairs. For that reason, new as well as used seals may only
be installed as original pairs.
Avoid impacts and blows, which could damage the sealing surfaces of the chilled cast sliprings.
Round off sharp edges on the seal mounts.
Slipring seals and their receptacles must be absolutely clean and free of grease and oil for installation.
O-rings may not be lubricated with oil.
Caution!
If the installation device is not used, the O-ring can roll up on the conical slipring surface. In
case of one-sided installation pressure, the seal half and / or the O-ring can twist. These
types of installation problems cause leaks as well as damage to the gliding surfaces.

1. General guidelines
1.1. Documentation for work to be carried out
For work to be performed, refer to the Maintenance and inspection schedule for your particular machine
model – see section 3.2.
Check off completed inspections or work by making a check mark on a copy of the form and have the
completed form countersigned.
The determined test values for the adjustment checks should be documented on an adjustment check list –
corresponding to the machine model, see paragraph 3.5.
In addition, confirm the performance of the inspection / delivery in the machine’s inspection booklet and send
the appropriate Service ticket to the appropriate LIEBHERR company. After removing the old sticker, attach the
new inspection sticker, which can also be found in the inspection booklet, clearly visible in the cab.
Explain the set up and the contents of the machine documentation to the machine operator. Special
emphasis should be given to safety regulations and maintenance task to be performed between inspections.
1.2. Safety guidelines
During all maintenance, inspection or repair work, the applicable safety guidelines according to section 1.2
and the operating instructions for the machine must be observed. In addition, all applicable Federal, state and
local safety requirements, accident prevention regulations and local laws must be observed.
1.3. Intervals
The given Maintenance and inspection intervals may not be exceeded, if necessary, they should be
shorted, for example: Changing filters, draining condensation and sediments in case of dirty fuel; cleaning the
radiator in case of contamination; changing filters and oils during or after repairs, etc.
Dispose of oil oils, filters and other waste products properly!
1.4. General
Use only LIEBHERR Original spare and maintenance parts for all maintenance, inspection and repair work.
If the operator requests other on hand parts for installation, then this must be noted separately on the inspection
check lists by noting possible loss of warranty.
For general screw tightening torques, see section 1.4. For tightening guidelines for track chain pads and
sprocket segment bolts, see section 12.1.

2. Maintenance and inspection guidelines
2.1. Inspection work on the Diesel engine
2.1.1 Check / adjust valve clearance
Preparation for test
Make sure that:
The machine is in maintenance position.
The battery master switch (optional) is turned off or the negative cable is disconnected from the
battery.
The Diesel engine is cold.
Special tools are available (turning tool – flywheel, adjustment pin, see section 2.1.)
If necessary, have new gaskets for the cylinder head covers ready for use.
Procedure:
Remove the rocker lever cover and the crankcase vent pipe.
Note!
Visually inspect the contact surfaces of the valve tips, valve bridges and rocker lever wear
surfaces. Check all parts for excessive wear, breakage and cracks. Replace any parts which
show visible damage.
Rocker levers, which show excessive valve clearance should be checked closely to determine
damaged parts.
Replace valves, seats, springs and retainers in pair per cylinder if they are damaged. In
addition, replace the bridge if one of these parts is being replaced.
Remove the plastic plug or the cover plate from the engine adjustment / rotary opening (A) and the
adjustment pin opening (B) on the flywheel side.
With the special tool “Turning device – flywheel“ turn the engine flywheel in direction of rotation (when
viewed from the front, turn it in clockwise direction until the cylinder No. 1 is on the top dead center (TDC) of
the compression stroke.
Insert the special tool „adjustment pin“ into the flywheel.

Note!
If the rocker levers of cylinder No. 1 can be moved, then the engine is on the TDC of No. 1 in
the compression stroke.
If the rocker levers of cylinder No. 1 cannot be moved, turn the engine a complete rotation
(360°) to the TDC No. 1 of the compression stroke.
When the engine is held with the adjustment pin on the TDC of the compression stroke of piston No. 1,
check the valve clearance according to the following specification.
Adjust valve clearance
Note!
If the valves must be adjusted, release the counter nut (A) on the rocker lever adjustment
screw. Prevent the adjustment screw from turning with a screw driver and tighten the counter
nut according to specifications. After tightening the counter nut, check the clearance again.
Readjust the clearance, if necessary.

2.2. Inspection work on the hydraulic system
2.2.2 Check the working and travel hydraulic system for function and leaks, check hose routing for chafing, check
mountings and fittings for tight seating
Carry out all travel and working movements and check for malfunction.
Check the actuator plate, plunger and universal joint of the working hydraulic pilot control for wear, grease
lightly and adjust, if necessary. The same applies for pilot control for auxiliary equipment.
To inspect the pressure accumulator – safety control – working hydraulic, start the Diesel engine and raise
the front attachment. Turn the engine off (return the ignition key again to position 1) and leave the safety lever
in the down position. Actuate the function “down” several times jerkily. If the attachment moves down less
than four times, then the accumulator is defective or there is excessive
leakage in the system.
Check the hose lines for leaks and kink-free routing. Watch for chafe
marks. Replace chafed, “sweating” or aging hoses. Refer to the Safety
guidelines, Section 1.2.
Do not route control, leak oil and tank line hoses with the HP hose lines in
one strand, and do not route them over sharp corners, edges or hose
fittings.
Check connections for leaks and replace seal rings, if necessary.
Check the piston rods for damage as well as the piston rod bearings for leaks. Fix, if necessary.
Check the mounting screws of hydraulic components (pumps, motors, hydraulic tank etc.) as well as the
flange connections for tight seating. Retighten, if necessary.
2.2.3 Check / adjust all hydraulic pressures
Carry out tests / adjustments according to the adjustment check list for the respective machine type – see
section 3.5 – and enter the results.
For detailed descriptions, data and instructions, see adjustment check list or corresponding sub group in the
Service Manual.
