Reassembly - Eaton Char-Lynn 2000 Series Parts And Repair Manual

Reassembly

Check all mating surfaces. Replace any parts that have
scratches or burrs that could cause leakage. Clean all metal
parts in clean solvent. Blow dry with air. Do not wipe dry
with cloth or paper towel because lint or other matter can
get in the hydraulic system and cause damage. Do not use
a coarse grit or try to file or grind these parts. Check around
the keyway and chamfered area of the shaft for burrs, nicks
or sharp edges that can damage the seals when reassem-
bling the bearing housing.
Lubricate all seals (prior to installation) with petro-
N Noee:

reassembling this motor. Refer to parts list (6-129) for
proper seal kit number.
21. Use a press to install exclusion seal in outer bore of
bearing housing. Lip of seal must face outward. See
Figure 11. If a press is not available use a plastic or
rubber hammer, being careful not to damage or cock
seal in the bore.
