3. With Retaining Ring (4K) installed on snap ring pliers,
place on top of Washer (4J) and compress Spring (4I)
until Retaining Ring (4K) is seated completely in groove.
4. Apply a liberal coat of grease to the bore of one Output
Planet Gear (4F).
5. Line the inside of the Planet Gear (4F) with 15 Needle
Rollers (4C).
NOTE: The last roller installed must be installed end wise. That is,
the end of the last roller must be placed in between the
ends of the two rollers that form the space, and then slid,
parallel to the other rollers, into place.
