42 Reposition the bearing housing in the vise so the output shaft is in
the down position.
43 Install the two case drain plugs in the bearing housing drain holes.
Use new o-rings and tighten the plugs to 81-122 Nm [60-90 lb-ft].
44 Pour a small amount of clean hydraulic fluid into the bearing
housing and output shaft.
45 Reinstall the drive spacer* if it was dislodged during disassembly.
Use a long thin rod to guide the drive spacer into the output shaft.
*Note: Do not use spacer with current motors or replacement shafts.
Motors with this shaft spacer will still have to be reassembled with
this spacer unless the shaft was damaged and must be replaced.
46 Apply petroleum jelly to the 108 mm [4.25 in.] seal and 9,5 mm
[.375 in.] o-ring. Install each in the appropriate groove in the bearing
housing (see Figure 17).
47 Put the rear thrust washer and rear thrust bearing into the recess in
the wear plate. The rear thrust washer goes in first. Petroleum jelly
may be used to hold these parts in place while the wear plate is being
installed.
48 Install the wear plate so the rear thrust washer is against the shaft
bearings. Be sure to align the case drain holes.
