19. You may need a press to remove shaft and bearing
assembly from bearing housing. (Key must be removed
before removing shaft.)
20. Use a small screwdriver to remove shaft seal, back–
up washer and exclusion seal from bearing housing, see
Fig. 78. Do not damage bore of housing.
NOTE: Individual parts of shaft and bearing assembly
are not sold separately. Replace as a unit.
Check all mating surfaces. Replace any parts that have
scratches or burns 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 dam-
age. 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 dam-
age the seals when reassembling the bearing housing.
NOTE: Lubricate all seals (prior to installation) with pe-
troleum jelly such as Vaseline. Use new seals when
reassembling this motor.
21. Use a press to install exclusion seal in outer bore of
bearing housing. Lip of seal must face outward. See Fig.
79. If a press is not available use a plastic or rubber ham-
mer, being careful not to damage or cock seal in the
bore.
22. Place back–up washer into seal bore. Place shaft
seal onto installation tool and press seal into seal bore
of the housing.
23. Clamp housing in vise, see Fig. 69.
24. Place protective bullet over shaft. Apply petroleum
jelly to inside diameter of dust and shaft seal. You may
need a press to install shaft and bearing assembly. Do
not distort shaft seal. Damage to this seal will cause
leakage.
NOTE: Use tape over other shafts to prevent cutting the
seats.
25. Apply petroleum jelly to the 3[76] diameter seal.
Install seal into the bearing housing.
