PLANET CARRIER SERVICE
PRIMARY PLANET CARRIER
CH210 ONLY
Disassembly
1. Remove the planet gears by first driving the roll pins
(Item 31) into the center of the planet gear shafts (Item
28).
2. Use a punch to drive the roll pins from the planet gear
shafts.
DO NOT
reuse the roll pins.
3. Now you can remove the planet shafts, bearings,
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 proper-
ly, the bearing should be replaced. The thrust washer
contact areas should be free from any surface irregu-
larities that may cause abrasions or friction. The gears
and shafts should be inspected for abnormal wear or
pitting. Replace if necessary
Assembly
1. Install a bearing into a planet gear and place a thrust
washer on each side of the gear. Position this assem-
bly into an opening in the carrier. Slide a planet gear
shaft through the carrier, thrust washer, bearing and
remaining thrust washer.
2. Carefully align the pin hole in the carrier with the hole
in the shaft and drive a new roll pin into place.
