1. Using the appropriate pressing tool, press on main bear-
ing until it is fully seated.
2. Insert the motor shaft bearing into the center bore of
the spindle. The bearing is a slight slip fit, but it may
require some press to assemble if the bearing becomes
misaligned.
3. Retain the bearing with the spiral retaining ring.
4. Line the bore of the output planet gear with 22 needle
rollers. Use grease to retain the needle rollers in the
bore.
5. Place tanged thrust washer into each planet "window"
of the spindle. Make sure the tang sits in the cast groove
on the inside of the window.
6. Place a thrust washer onto the plane gear. Line up the
bores as best as you can. Use grease to hold the thrust
washer in place.
7. Slide the planet gear into the window with the tanged
washer until the bores line up.
