Power Train Disassembly & Assembly
Remove the Planetary Spider
Assembly
1. With a lifting device, remove the planetary spider
assembly (8) from the wheel hub (24) and set it on
a work bench. Rest the spider on its large flange
end.
2. Remove the capscrews (4) and washers (5) that
mount the cover (3) to the planetary spider (8).
Remove the cover.
3. If the axle shaft thrust button (6) requires
replacement, support the planetary spider cover
(3) in the area immediately adjacent to the thrust
button (6). Press the thrust button out of the cover.
4. If the planetary ring gear (17) did not remain with
the planetary spider assembly during the
assembly’s removal, remove the ring gear from the
planetary ring gear hub (20).
5. Match mark the large ends of the planetary pinion
shafts (10) and the planetary spider (8) to aid in
reassembly if the original pinion shafts are used.
6. Place the planetary spider assembly (8) on blocks
with the large flange end facing UPWARD.
Observe all warnings and cautions provided by
the press manufacturer to avoid damage to
components and serious personal injury.
Use a brass or leather mallet for assembly and
disassembly procedures. Do not hit steel parts
with a steel hammer. Pieces of a part can break off
and cause serious personal injury.
CAUTION : Avoid damage to the pinion shaft when it
falls out of the spider. Provide a soft cushion.
7. Use a press to remove the pinion shafts (10) out of
the spider. If a press is not available, use a brass
drift and mallet to drive out the shaft. Press or
drive the pinion shaft out toward the small end of
the spider which faces DOWNWARD.
8. Remove the planetary pinions (11) and thrust
washers (12) from the planetary spider.
9. Remove the axle shaft (33), planetary sun gear
(14) and snap ring (13) assembly.
NOTE : The sun gear thrust washer (15) may come
out with the axle shaft and sun gear assembly.
10. Remove the snap ring (13) from the axle shaft
(33) to allow for the removal of the sun gear (14)
from the axle shaft.
11. If necessary, remove the sun gear thrust washer
(15) from the axle shaft.
12. If necessary, remove the sun gear thrust washer
from the end of the spindle (30).
13. Remove the two lock plate capscrews (18).
Remove the lock plate (19) from the planetary
ring gear hub (20).
14. Remove the wheel bearing adjusting nut (16).
15. Remove the planetary ring gear hub (20). The
outer wheel bearing cone (21) usually remains on
the ring gear hub. If it needs to be replaced,
remove it from the hub.
16. Remove the wheel hub (24). The hub oil seal (29)
and inner bearing assembly (27, 28) will remain
in the hub.
CAUTION : Do not damage the hub oil seal bore
surface in the wheel hub. Damage to this surface will
result in oil leakage after assembly.
17. Remove the hub oil seal (29).
18. Remove the inner bearing cone (28).
19. If replacement of the wheel bearings is
necessary, press out the outer bearing cup (22)
and inner bearing cup (27).
20. Remove and discard the O-ring (23) from the
wheel hub (24).
