GENERAL INFORMATION
Cleanning
Clean all metal parts except bearings, in a suitable
cleaning solvent or by steam cleaning. Do not use
caustic soda for steam cleaning. After cleaning, dry
and put oil on all parts. Clean oil passages with
compressed air. Clean bearings in a suitable cleaning
solvent, dry the bearings completely and put oil on
the bearings.
Inspection
Check all parts when the parts are disassembled.
Replace all parts that have wear or damage. Small
scoring or grooves can be removed with a hone or
crocus cloth. Complete a visual inspection for
indications of wear, pitting and the replacement of
parts necessary to prevent early failures.
Bearings
Check bearings for easy action. If bearings have a
loose fit or rough action replace the bearing. Wash
bearings with a suitable cleaning solvent and permit
to air dry. DO NOT DRY BEARINGS WITH
COMPRESSED AIR.
Needle bearings
Before you press needle bearings in a bore always
remove any metal protrusions in the bore or edge of
the bore. Before you press bearings into position put
petroleum jelly on the inside and outside diameter of
the bearings.
Gears
Check all gears for wear and damage. Replace gears
that have wear or damage.
Oil seals, O-rings and gaskets
Always install new oil seals, O-rings and gaskets. Put
petroleum jelly on seals and O-rings.
Shafts
Check all shafts that have wear or damage. Check
the bearing and oil seal surfaces of the shafts for
damage.
Service parts
Always install genuine Case service parts. When
ordering refer to the Parts Catalog for the correct part
number of the genuine Case replacement items.
Failures due to the use of other than genuine Case
replacement parts are not covered by warranty.
Lubrication
Only use the oils and lubricants specified in the
Operator’s or Service Manuals. Failures due to the
use of non-specified oils and lubricants are not
covered by warranty.

FLUIDS AND LUBRICANTS
Lubricants must have the correct properties for each application.
Hydraulic fluid
CASE/AKCELA hydraulic fluid is specially designed for high pressure applications and for the CASE hydraulic sys-
tem. The type of fluid to be used depends on the ambient temperature.
Temperate climates: -20°C to +40°C (-4° to 104° F)
CASE/AKCELA: HYDRAULIC EXCAVATOR FLUID (MS 1230. ISO VG 46. DIN 51524 PART 2 HV)

Engine Oil
THE CASE/AKCELA No. 1 engine oil is recom-
mended for your engine. This oil ensures proper
lubrication of your engine for all operating conditions.
If you are unable to procure the CASE No. 1 Multiper-
formance or Performance engine oil, use the corre-
sponding oil from the API/CG/CF category.
NOTE: Do not put any Performance Additives or any
other additives in the engine housing. The oil
changing intervals are indicated in the Operator’s
manual based on tests carried out on CASE
lubricants.

Fuel
Use fuel which is to ASTM (American Society for Testing and Materials) D975 standard.
Use grade No. 2-D fuel. The use of other types of fuel can result in a loss of power of the engine and may cause
high fuel consumption.
In cold weather (below -7°C), it is provisionally approved to use a mixture of fuels No. 1-D and No. 2-D.
If the temperature falls below the fuel cloud point (point at which wax begins to form) the wax crystals will cause
power loss or will prevent the engine from starting.
Required conditions for diesel fuel
The following specific conditions are required for diesel fuel:
- Must be free from minute dust particles.
- Must have adequate viscosity.
- Must have high cetane value.
- Must have high fluidity at low temperature.
- Must have low sulphur content.
- Must have little residual carbon.
Diesel fuel recommendation
- JIS (Japanese Industrial Standard) : No. 2
- DIN (Deutsche Industrie Normen) : DIN 51601
- SAE (Society of Automotive Engineers) Based on SAE-J-313C: No. 2-D
- BS (British Standard) Based on BS/2869-1970: Class A-1
IMPORTANT : If fuel other than the specified one is used, engine operation will be impaired.
Using fuels other than those recommended can damage the fuel injection pump, the injector and other parts of the
fuel supply system and the engine. CASE disowns any responsibility concerning this kind of damage, which
is not covered by the guarantee. To avoid any damage to the engine fuel supply system, you are recommended
to take the following safety messages into account:
Some fuel suppliers mix used engine oil with diesel fuel. Certain manufacturers of large engines allow them to do
this. However, for your engine, do not use diesel fuel contaminated by engine oil. In addition to damaging the
engine, this fuel can actually adversely affect the correct purification of exhaust gases. Before using any diesel fuel,
ask the supplier if this fuel has been mixed with engine oil.
IMPORTANT : For use of the correct fuel additives, consult your oil or lubrication supplier. Do not inject fuel oil or
gasoline, both fuels can damage the engine.
IMPORTANT : In cold weather, fill the fuel tank at the end of the day's work, in order to prevent the formation of con-
densation.
Fuel storage
Long storage can lead to the accumulation of impurities and condensation in the fuel. Engine trouble can often be
traced to the presence of water in the fuel.
The storage tank must be placed outside and the temperature of the fuel should be kept as low as possible. Drain
off water and impurities regularly.

15. 1002-7
Lep 9-94170EN Issued 02-06
Anti-freeze/Anti-corrosion
Use anti-freeze in all seasons to protect the cooling system from corrosion and all risk of freezing.
CASE/AKCELA: PREMIUM ANTI-FREEZE (MS 1710)
For areas where the temperature goes down to -38°C, mix 50/50 with water.
IMPORTANT : Do not mix products of a different origin or brand. The same product must be used when topping up
the system.
Environment
Before carrying out any maintenance operation on this machine and before disposing of used fluids or lubricants,
always think of the environment. Never throw oil or fluid on the ground and never place it in leaking receptacles.
Contact your local ecological recycling centre to obtain information on the correct method of disposing of these
lubricants.
Plastic and resin parts
When cleaning plastic parts, the console, the instrument panel, the indicators etc... avoid using petrol, kerosene,
paint solvents etc... Use only water, soap and a soft cloth.
The use of petrol, kerosene, paint solvents etc... causes discoloration, cracks or deformation of these parts.

RADIATOR, OIL-COOLER, INTER COOLER AND FUEL COOLER
Before carrying out any operation on the machine, perform the following operations in the order shown:
- Park the machine on hard, flat ground.
- Lower the attachment to the ground.
- Shut down the engine.
- Remove the starter switch key.
- Make sure that pressure in the hydraulic system has been completely released (see Operator’s Manual).
Removal
NOTE: For the removal refer to the figure 1, page 6.
STEP 1
Drain the cooling system (see Operator’s Manual).
STEP 2
Release pressure in the hydraulic reservoir to allow
the vacuum pump to be mounted (see Section 8000).
Installation
NOTE: For the installation refer to the figure 1, page
6, proceed in the reverse order from that of removal.
1) Coat the thread of reference (40) and (51) with loc-
tite or equivalent after removing any oil film and fas-
ten by tightening torque .
2) Apply packing liquid (38) to the connection of radi-
ator hose after removing any oil film and fasten by
tightening torque.
3) Tighten up the hose band from the direction
schown on the D.W.G.
Before operating the machine:
- Check the oil level in the hydraulic reservoir. Top up
if necessary.
- Check the hydraulic fluid cooling circuit for leaks.
- Fill and bleed the engine cooling system (see Oper-
ator’s Manual).
- Check the engine cooling system for leaks.
WARNING: When the machine is working, the engine components and the hydraulic pump reach a high
temperature. To avoid being burnt by hot metal or scalded by high temperature water or oil, allow the
machine to cool down before starting any servicing operation.
