Reassembly
Check all mating surfaces. Replace any parts that have scratches or
burrs that couId cause leakage. Clean all metal parts in clean solvent.
Blow dry with air. Do not wipe with cloth or paper towel because lint
or other matter could get into the hydraulic system and cause damage.
Do not use a coarse grit papers/cloth or try to file or grind motor parts.
Check around the keyway and chamfered area of the shaft for burrs,
nicks, or sharp edges that can damage the seals when reassembling
the retainer.
Note: Lubricate all seals (prior to installation) with petroleum jelly
such as Vaseline
®
. Use new seals when reassembling the motor.
Refer to parts list (6-127 6000 Series -005 and 6-159 6000 Series -
006) for replacement parts and proper kit number.
20 Place bearing housing on smooth flat surface with largest open end
of housing up.
Apply petroleum jelly to shaft face seal. Install seal in seal seat. Seat
seal properly in groove (see Figure 11 and 14). A damaged or
improperly installed shaft face seal could cause internal lubrication
loss and subsequent parts wear.
21 Install shaft and bearing assembly in bearing housing (see Figure
12). Do not damage seal in bore of housing. You may need a press to
install shaft and bearing assembly.
22 Use a small press, if available, to install dust seal in retainer. Metal
side of dust seal must face toward retainer as shown in Figure 14. If a
press isn’t available, use a plastic or rubber hammer to tap dust seal in
place.
23 Install 92,3 [3.64] I.D. seal, back-up ring and shaft seal in retainer.
Flat or smooth side of shaft seal must face toward retainer as shown in
Figure 14. Apply petroleum jelly to inside diameter of shaft seal (after
installing seal).
24 Before installing retainer, place a protective sleeve of bullet (see
note below) over shaft. Grease inside diameter of dust and shaft seals.
To prevent damage to seals, install retainer over shaft with a twisting
motion. Do not cut or distort shaft seal. Damage to shaft seal will
cause external leakage.
Note: Bullet 600464 for 1-1/2 inch diameter shafts available—by
special order through our service department.
