6-15.
TRANSMISSION REPAIR (Continued).
(n) Working through the front of carrier
assembly (277), remove snapring (281).
Tap the shaft assembly (278) rearward,
and remove it from the carrier assembly.
(o) Press the shaft assembly (278) from ball
bearing (279).
(p) Remove spring pin (280), needle roller
bearing (282), and cup plug (283) from
shaft (270) only if parts replacement is
necessary.
(2) Planetary carrier repair.
NOTE
The procedures for all planetary carrier
assemblies differ only in the proper tool
selection for the specific application.
The special tool chart details the tool
number
required
for
a
specific
application and identifies the carrier
involved (front, center and rear). If the
tool is common to all of the planetary
carrier assemblies, its number will not
be listed in the test. If the tool is not
common, the test will refer to the chart.
(a) Visually inspect planetary carrier assembly
for evidence of excessive wear, overheat
indication,
damage
or
heavy
metal
contamination.
(b) Check end play of planetary carrier
pinions. With washer held flat, insert feeler
gauge between carrier and thrust washer.
End play must be within 0.008-0.031 inch
(0.20-0.79 mm).
CAUTION
Do not disassemble carrier assembly unless parts
replacement is necessary. Failure of one pinion
requires replacement of the entire pinion gear set
because they are selectively matched.
NOTE
Complete replacement of the assembly may be
warranted, depending on the amount of labor, time,
parts replacement and extent of repair.
(c) Fabricate six dummy pins (284) for front
carrier
which
are
0.5117/0.5114
inch
(12.99/12.98 mm) diameter by 2.50 inch
(63.5 mm) long.
(d) Place the front carrier on a work table, rear
downward.
(e) Press the bushing (284) (front carrier only)
from the carrier. Do not scratch or score
the bushing bore.
(f) Place
the
carrier
in
a
press,
rear
downward.
(g) Apply loctite (Appendix D, Item 27) to the
outer diameter of a new bushing (285).
Using bushing installer tool, install the new
bushing into the bore of the front planetary
carrier. Press the bushing 0.265-0.275 inch
(6.73-6.99 mm) below its adjacent surface.
