Assembly Procedure
Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned
in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts.
Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are
worn or damaged, use new parts for replacement. All disassembly and all assembly procedures
must be performed on a clean work surface and in a clean hydraulic area. Keep cleaned parts
covered and protected at all times.
Note: O-rings, gaskets, and seals should always be replaced. A used O-ring may not have the
same sealing properties as a new O-ring. Use 1U-6396 O-Ring Assembly Compound during the
assembly procedure.

16. 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
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: A hydraulic oil sample should be obtained before any maintenance is performed in
order to establish the system contaminant level. Refer to Fluid Analysis Laboratory Guide,
SEBF3116, "Obtaining an Oil Sample for S·O·S Analysis". Refer to Operation and
Maintenance Manual, "Sampling Interval and Location of Sampling Valve" for the correct
location.
