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.

7. 1001-5
Lep 7-27691NA Issued 02-06
WARNING: Use insulated gloves or mittens
when working with hot parts.!
WARNING: Lower all attachments to the
ground or use stands to safely support the
attachments before you do any maintenance
or service.
!
WARNING: Pin sized and smaller streams
of hydraulic oil under pressure can penetrate
the skin and result in serious infection. If
hydraulic oil under pressure does penetrate
the skin, seek medical treatment
immediately. Maintain all hoses and tubes in
good condition. Make sure all connections
are tight. Make a replacement of any tube or
hose that is damaged or thought to be
damaged. DO NOT use your hand to check
for leaks, use a piece of cardboard or wood.
!
WARNING: When removing hardened pins
such as a pivot pin, or a hardened shaft, use
a soft head (brass or bronze) hammer or use
a driver made from brass or bronze and a
steel head hammer.
!
WARNING: When using a hammer to
remove and install pivot pins or separate
parts using compressed air or using a
grinder, wear eye protection that completely
encloses the eyes (approved goggles or
other approved eye protectors).
!
WARNING: Use suitable floor (service)
jacks or chain hoist to raise wheels or tracks
off the floor. Always block machine in place
with suitable safety stands.
!
WARNING: When servicing or repairing the
machine, keep the shop floor and operator’s
compartment and steps free of oil, water,
grease, tools, etc. Use an oil absorbing
material and/or shop cloths as required. Use
safe practices at all times.
!
WARNING: Some components of this
machine are very heavy. Use suitable lifting
equipment or additional help as instructed in
this Service Manual.
!
WARNING: Engine exhaust fumes can
cause death. If it is necessary to start the
engine in a closed place, remove the exhaust
fumes from the area with an exhaust pipe
extension. Open the doors and get outside
air into the area.
!
WARNING: When the battery electrolyte is
frozen, the battery can explode if (1), you try
to charge the battery, or (2), you try to jump
start and run the engine. To prevent the
battery electrolyte from freezing, try to keep
the battery at full charge. If you do not follow
these instructions, you or others in the area
can be injured.

5 Disassembly instructions
[1] Preparation
Prior to disassembly, take full preparatory measures.
1) Workbench with vises
Prepare a suitable workbench large enough to arrange and keep parts and perform the work.
2) Tools and Jigs
For tools and jigs, refer to the previous section.
[2] General cautions
1) Handle precision parts carefully during the operation; do not drop or hit them on other parts during the operation.
2) Do not attempt to finish the operation quickly; do not forcedly pry or hit the parts.
Perform the operation carefully and patiently in order to prevent parts deformation, oil leakage and lower effi-
ciency.
3) As disassembled parts tend to get rusted or collect dust and dirt, dust proof and rust prevention treatment should
be applied immediately after disassembling the parts.
