1. Remove the planet gears by driving the roll pins into the
center of the planet shafts (Figure 11-86).
2. Use a punch (Figure 11-87) to drive the roll pins from the
planet shafts. Do not reuse the roll pins.
3. Now you can remove the planet shafts, bearings,
spacer, thrust washers and gears.Thoroughly clean all
parts and inspect for damage and wear. The bearing
rollers should not exhibit any irregularities. If the 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 may cause abrasions or friction. The
gears and shafts should be inspected for abnormal wear
or pitting. Replace if necessary.
