er when properly installed. With a center punch, stake
the carrier next to the pin hole as shown. This will dis-
tort the hole and prevent the pin from backing out in
operation. Repeat these steps for each of the three
planet gears.

1. Follow steps 1 and 2 of the Primary Planet Carrier dis-
assembly procedure to remove the roll pins from the
planet gear shafts.
2. Now you can remove the planet shafts, bearings, spac-
ers, thrust washers and gears. Thoroughly clean all
parts and inspect for damage and wear. The bearing
rollers should not exhibit any irregularities. If the roll-
ers show any sign of spalling, corrosion, discoloration,
material displacement or abnormal wear, they should
be replaced. The thrust washer contact areas should
be free from any surface irregularities that may cause
abrasions or friction. Inspect gears and shafts for ab-
normal wear or pitting and replace if necessary.

Assembly
1. Place the output carrier on a clean work surface with
the drive pins down. Install the output thrust plate (Item
102) into the center of the carrier.
2. Apply a liberal coat of oil soluble grease to a thrust
washer and center it on one side of a planet gear.
Place the planet gear on a clean work surface with the
thrust washer down. Apply a liberal coat of oil soluble
grease to the bore of the gear. Stack a row of loose
roller bearings into the planet gear, using the grease to
hold them in position. There are 22 rollers in each row.
Install a bearing spacer. Stack a second row of loose
roller bearings on top of the bearing spacer. Place a
second thrust washer on the planet gear. Carefully
slide the planet gear, bearings and thrust washers into
the carrier. Install a planet gear shaft into the carrier
and through the planet gear bearings.
3. Follow steps 2 and 3 of the Primary Planet Carrier as-
sembly procedure to install and stake a NEW roll pin in
the carrier.
Repeat this procedure for each of the planet gears.
