Sub Assembly - Planet Carrier Unit
• Place planet carrier with large diameter face up
with planet gear access hole facing the mechanic.
• Smear clean grease into bore of one planet gear.
• Insert planet gear and thrust washer into planet
carrier.
• Lightly oil O-ring and O-ring grove in planet pin
with clear gear oil then fit 'O'ring into planet pin.
• Insert planet pin, O-ring up into planet carrier and
through planet gear making sure to line up flat on
planet pin with hole in planet carrier for set
screw.
• Clean set screw threads with solvent then apply
Loctite 275. Drive screw into hole in planet
carrier and tighten to a torque of 22-27 lbs. ft.
(30-36 N•m) to secure planet pin assembly.
• Repeat operations for other two planet gear
assemblies.
• Stake screw in four places to lock in position.
• Coat thrust button bore, in planet carrier, with

gear splines.
• Coat hub mating face of planet carrier with
Loctite 515 joining planet carrier unit with hub
using chain hoist if required. Ensure planet gear
teeth mesh with sun gear.
• Fit planet carrier capscrews and hardened
washers, tighten to a torque of 91-101 lbs. ft.
(123-137 N•m).
• Fit drain capscrew and washer, tighten to a torque
of 145-161 lbs. ft. (196-218 N•m).
• Fit planet cover plate, secure with capscrew,
tightening to 66-72 lbs. ft. (89-98 N•m).
• Rotate both hubs until oil filler/level plug holes
are on axle center line, fill with oil until level with
