REAR PLANETARY CARRIER
ASSEMBLY
NOTE
Disassemble the planetary assembly
only if there is evidence of undue wear
or damage.
Failure of one pinion
requires the replacement of the entire
set, because the pinions are selectively
matched.
a. Disassembly (A, foldout 13)
(1)
If carrier 40 or bushing 41 is damaged or
otherwise unserviceable, replace with a carrier and
bushing assembly.
Field replacement of the bushing
alone is not recommended.
(2)
Using
a31/32-inch
drill,
centered
accurately, drill into one end of each pinion
pin 46 until the swaged end is sufficiently weakened.
CAUTION
Do not drill into metal of carrier 40.
(3)
Place carrier assembly 38 in a press, and
press four pins 46 from carrier 40, shearing the drilled
ends of pins 46.
(4)
Remove, as a unit, each of the four pinion
groups consisting of pinions 43, thrust washers 42 and
45, and needle roller bearings 44.
NOTE
Refer to paragraph 6-2, above.
b. Assembly (A, foldout 13)
NOTE
To facilitate assembly, it is permissible
to freeze pinion pin 46 or heat carrier 40
before pinion pin installation.
(1)
Install a needle roller bearing 44 into the
bore of each pinion 43.
Place a steel thrust washer 45
(first) and a bronze thrust washer 42 (second) onto each
face of pinions 43.
(2)
Position carrier 40, front downward
(bushing bore upward), in a press.
Place a pinion group
(as assembled in (1), above) into the carrier.
Align the
pinion group with the pinion pin bore in the carrier.
(3)
Install a pinion pin 46, and press it through
the carrier and pinion group, to the dimension shown in
figure 6-72.
NOTE
Pins must be a tight, to moderately tight,
press fit (when parts are at normal
temperatures).
