1. Drive the three (3) spiral pins into the center of the
planet gear shafts.
3. To disassemble the primary planet carrier assembly,
the steps are the same as for the output planet carrier
assembly, except there is only one bearing for each
gear. Also, the primary carrier has a thrust washer
inside that can be removed after the planet gears are
removed.
OUTPUT PLANET CARRIER SERVICE
2. 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. The
CH150A, C2H150A, CH175A and C2H175A also have
a bearing spacer between each pair of bearings that
has to be removed.
5. Use a punch to drive the spiral 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.
4. If the rollers show any sign of spalling, corrosion, dis-
coloration, 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 exces-
sive abrasion or friction. The gears should be inspect-
ed for abnormal wear or pitting. Replace if necessary.
