PRIMARY PLANET CARRIER SERVICE
DISASSEMBLY
1.
Apply light pressure to the thrust ring (Item 10) and re
-
move the retaining ring (11). Then remove thrust ring,
brake plates, friction discs, and wave springs (7,8,9)
from the carrier.
2.
Remove the planet gear shafts (55) by driving the roll
pins (58) into the center of the shafts. Slide the planet
gear shafts out of the carrier. Use a punch to drive the
roll pins out of the gear shafts. DO NOT reuse the roll
pins; replace with new during reassembly.
3. Remove the planet gears, bearings, and thrust wash-
ers (54,56,57) from the carrier (53).
4. Thoroughly clean and inspect all planetary compo-
nents for abnormal wear or damage. The bearing roll-
ers should not exhibit any irregularities. If rollers show
any sign of spalling, corrosion, discoloration, mate-
rial displacement, or other abnormal wear, replace
bearing(s). Inspect the bearing cage for unusual wear
or deformation, particularly the cage separator bars.
If there is any damage that will impair the ability of
the cage to separate, retain, guide the rollers properly,
the bearing MUST be replaced. The thrust washer
contact areas must be free of serious surface irregu-
larities that may cause abrasion or friction. The gears
and planetary shafts should be inspected for abnormal
wear or pitting. Replace all components as required.
NOTE:
Use care in handling the carrier to prevent damag-
ing the hub on the gear side of the carrier, because this is
a bearing surface.
ASSEMBLY
1.
Install the bearing (57) into a planet gear (54). Place a
thrust washer (56) on each side of the gear and insert
the gear assembly into an opening in the carrier (53).
Slide the planet shaft through the carrier, and into and
through the gear and thrust washers.
2.
Carefully align the pin hole in the carrier (58) with the
hole in the planet shaft, and drive a NEW roll pin into
place. The roll pin should be recessed into the carrier
to a depth of .35 inch (9 mm). Using a center punch,
stake the carrier next to the pin hole. This will distort
the hole so that the roll pin will not back out in service.
3. Repeat for each of the planet gears.
4.
Install the thrust ring (10) into the carrier on top of the
clutch pack.
