Input Carrier Subassembly
1. Apply a liberal coat of grease to the bore of the Planet Gear (8F). This will enable the Needle
Rollers (8C) to be held in place during assembly.
2. Install Needle Rollers (8C) into the bore of each of the three Planet Gears (8F).
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 slide
parallel to the other rollers into place.
3.
Place the Carrier (8A) into the tool fixture so that one of the roll pin holes is straight up.
4.
Start Planet Shaft (8D), with end opposite roll pin hole first, through the planet shaft hole in
Carrier (8A), making sure that the roll pin hole in the planet shaft is straight up.
5.
Using ample grease to hold them in position, slide four Washers (8B) onto the Planet Shaft
(8D).
6.
Place the Planet Gear (8F) into position and push the Planet Shaft (8D) through the planet
gear without going all the way through carrier.
