NOTE
Pins must be a tight, to moderately tight,
press fit (when parts are at normal
temperatures).
(5) Install the remaining pinion groups and pins in
the manner described above.
(6) Support each pinion pin on a 1/2inch (12.
7 mm)
(approx.) anvil.
Using a suitable punch, swage
the pins firmly against the carrier to form the
pattern shown in figure 6-68.
Pinions must
rotate freely after swaging.

CENTER PLANETARY CARRIER ASSEMBLY
NOTE
Refer to paragraph 6-26 for removal
from gear unit.
Disassemble the
planetary assembly only if there is
evidence of undue wear or damage.
Failure
of
one
pinion
requires
replacement of the entire set because
the pinions are selectively matched.
a. Disassembly (A foldout 13)
(1) Using a31/32-inch drill, centered accurately, drill
into one end of each pinion pin 17 until the swaged end
is sufficiently weakened.
CAUTION
Do not drill into metal of carrier 18.
(2) Place carrier assembly 16 in a press, and press
four pins 17 from carrier 18, shearing the drilled ends of
pins 17.
(3) Remove as a unit, each of the four pinion groups
consisting of pinions 20, thrust washers 19 and 22, and
needle roller bearings 21.
Remove bearings from pinion
bores.
NOTE
Refer to paragraph 6-2, above.
b. Assembly ( A foldout 13)
NOTE
To facilitate assembly, it is permissible
to freeze pinion pin 17 or heat carrier 18
before pinion pin installation.
(1) Install two bearings 21 into the bore of each
pinion 20.
Place a steel thrust washer 22 (first) and a
bronze thrust washer 19 (second) onto each face of
pinions 20.
(2) Position carrier 18 in a press, and place a pinion
group (as assembled in (1), above) into the carrier.
Align
the parts of the pinion group with the pinion pin holes in
the carrier.
(3) Install pinion pin 17 and press it through the
carrier and pinion group to the dimension shown in figure
6-69.
NOTE
Pins must be a tight, to moderately tight,
press fit (when parts a r e at normal
temperatures).
(4) Install the remaining pinion groups and pins in
the manner described above.
(5) Support each pinion pin on an 0.812-inch (20.62
mm) (approx.) anvil.
Using a suitable punch, swage the
pin firmly against the carrier to form the pattern shown in
figure 6-69.
After swaging, each pinion must rotate
freely.
