1. Using a punch, drive the spirol pins into the center of
the planet gear shafts.
2. Remove the planet gear shafts, thrust washers,
bearings and planet gears from the carrier.
NOTE:
The output planet carrier has two (2) bear-
ings per planet gear. The primary planet carrier has
only one (1) bearing per planet gear.
3. On the primary planet carrier only, remove the thrust
washer from the pocket inside the carrier after the
planet gears have been removed.
4. Inspect the roller bearings closely for wear or dam-
age. Inspect the bearing rollers for spalling, corro-
sion, discoloration, displaced material or abnormal
wear. Inspect the bearing cage for unusual wear or
deformation, particularly on the cage separator bars.
Any damage that will impair the bearing cage's abil-
ity to separate, retain and properly guide the rollers
is cause for replacement.
5. Inspect the thrust washers. Ensure the contact faces
are free from any defect or surface irregularity that
can cause excessive friction or abrasion. Replace as
needed.
6. Inspect the planet gears for abnormal wear, pitting or
cracking. Replace as needed.
7. Use a punch to drive the spirol pins out of the plan-
et gear shafts, and discard the spirol pins. Inspect
the bearing surface of the shafts for abnormal wear,
spalling, discoloration, displaced material or corro-
sion. Replace as needed.
8. Inspect the planet carrier gear shaft bores. Ensure
they are smooth with no burrs, and there is no elon-
gation of the holes.
