before opening any compartment or disassembling any component
containing fluids.
Refer to Special Publication, NENG2500, "Dealer Service Tool
Catalog" for tools and supplies suitable to collect and contain fluids on
Cat®
products.
Dispose of all fluids according to local regulations and mandates.
NOTICE
Failure to properly assemble parts or failure to follow established
procedures can lead to damage to the parts and assembly.
To avoid damage to parts, always identify and mark the parts so that
they can be installed into the same location. Never force parts during
assembly. Keep parts clean and lubricated.
NOTICE
Keep all parts clean from contaminants.
Contamination of the hydraulic system with foreign material will
reduce the service life of the hydraulic system components.
To prevent contaminants from entering the hydraulic system, always
plug or cap the lines, fittings, or hoses as they are disconnected. Cover
any disassembled components and clean them properly before
assembly.
Clean the hydraulic system properly after any major component
exchange or especially after a component failure, to remove any
contamination.
Note: If a failure occurs, an accurate diagnosis of the cause can prevent a recurrence. Information
is available to analyze failures for piston pumps and motors. Refer to Special Publication,
SEBD0641, "Analyzing Axial Piston Pump and Motor Failures".
Note: Inspect all parts. If any parts are worn or damaged use new parts for replacement. The
installation of used parts during reconditioning is acceptable. Reuse and salvage information is
available on piston pumps. Refer to Guideline for Reusable Parts and Salvage Operations,
SEBF8032, "Piston Pumps and Motors". During reconditioning, correct any conditions that might
have caused the original failure.

NOTICE
Keep all parts clean from contaminants.
Contamination of the hydraulic system with foreign material will
reduce the service life of the hydraulic system components.

15. To prevent contaminants from entering the hydraulic system, always
plug or cap the lines, fittings, or hoses as they are disconnected. Cover
any disassembled components and clean them properly before
assembly.
Clean the hydraulic system properly after any major component
exchange or especially after a component failure, to remove any
contamination.
Note: If a failure occurs, an accurate diagnosis of the cause can prevent a recurrence. Information
is available to analyze failures for piston pumps and motors. Refer to Special Publication,
SEBD0641, "Analyzing Axial Piston Pump and Motor Failures".
Note: Inspect all parts. If any parts are worn or damaged use new parts for replacement. The
installation of used parts during reconditioning is acceptable. Reuse and salvage information is
available on piston pumps. Refer to Guideline For Reusable Parts and Salvage Operations,
SEBF8032, "Piston Pumps and Motors". During reconditioning, correct any conditions that might
have caused the original failure.
Note: O-ring seals , gaskets, and seals should always be replaced. A used O-ring seal may not
have the same sealing properties as a new O-ring seal. Use Tooling (H) during the assembly
procedure.
Note: Apply a light film of "10W" oil to all components before assembly.
