Housing-Ring Gear Subassembly
1. Insert Input Shaft (9) into mesh with Coupling’s (7) inter-
nal splines and place the Thrust Washer (4H) into coun-
terbore of Spindle (1A).
2. Place one of the Planet Gear Subassemblies (4F) into
Spindle (1 A) through gap between two Studs (1H).
Align the planet gear bore with one of the planet shaft
holes on the Spindle-Brake Subassembly using the Drift
Pin Assembly Tool.
3. Insert Planet Shaft (4E) into the planet shaft hole
described in Step (2) on Spindle (1A). The end of the
planet shaft that does NOT have the roll pin hole should
be inserted into the spindle FIRST.
4. Now insert Planet Shaft (4E) through the first set of
Thrust Washers (4B), Planet gear, then the second set of
Thrust Washers (4B). Use an alignment punch or similar
tool to align roll pin holes on Spindle (1A) and Planet
Shaft (4E).
NOTE: Be sure not to hit the planet gears when driving in the roll
pins.
5. Drive Roll Pin (4G) down into the aligned roll pin holes.
Pin should be flush with OD of spindle.
