PLANET CARRIER SERVICE
Disassembly
NOTE: The illustrations show the output carrier assem-
bly. Follow the same steps to service the primary carri-
er. The only difference is that the primary planet gears
have only one bearing, and no bearing spacer.
Drive the three (3) spiral pins into the center of the plan-
et gear shafts.
Remove one (1) planet gear shaft, two (2) thrust wash-
ers, two (2) roller bearings and one (1) planet gear from
each of three (3) locations in the carrier.
NOTE: The primary carrier gears have only one roller
bearing, and no spacer.
After all planet gears are removed, remove the thrust
washer from the carrier.
Use a punch to drive the spirol pins out of the planet
gear shafts. The same surface and material conditions
that are detrimental to the life of the bearings and thrust
washers also apply to the contact areas on the shafts
and carrier.
Thoroughly clean and inspect all planet carrier parts. If
the bearing rollers show any sign of spalling, corrosion,
discoloration, material displacement or abnormal wear,
the bearing should be replaced. Likewise, the cage
should be inspected for unusual wear or deformation,
particularly the cage bars. If there is any damage that
will impair the cage’s ability to separate, retain and
guide the rollers properly, the bearing should be
replaced. The thrust washer contact areas should be
free from any surface irregularities that cause excessive
abrasion or friction. The gears should be inspected for
abnormal wear or pitting. Replace if necessary.
