PLANET CARRIER SERVICE
OUTPUT PLANET CARRIER
DISASSEMBLY
1. Remove the planet gears by driving the roll pins into
the center of the planet shafts.
2. Use a punch 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 bear-
ing rollers should not exhibit any irregularities. If the
rollers show any sign of spalling, corrosion, discol-
oration, 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 nec-
essary.
ASSEMBLY
1. Place the output planet carrier on workbench with
splined coupling side down. Install output thrust plate
in center of carrier.
