12. Install rear carrier (4) front bearing cone.
Check output bearing preload.Output bearing pre-
load must be checked and/or adjusted if any of the
following items have been replaced:
Output shaft (rear carrier assembly)
Output shaft bearings
Transmission case
13.PRELOAD CHECK/SHIM SELECTION:Install
rear output shaft bearing cone and Support Plate
6618A (1).
Page 2954 of 5267
14. Install Support Plate 6618A (1). Lightly tighten
retaining screws. Screws should be below the
plate surface, but do not snug screws.
15. Turn case over on arbor press so that the plate is
resting on the press base.CAUTION: The output
shaft will extend through the hole of Support
Plate 6618A. Ensure your press table has
clearance for the output shaft.
16. Install shim (1) on output shaft (2). Apply small
amount of petrolatum onto the shim to hold it in
place. Use the original shim as a starting point. If
original shim is not available, use the thickest
shim available.

17. Install output shaft/rear carrier into rear bearing.
The shaft must be pressed into position. Use Disc
MD-998911 (2), Universal Handle C- 4171 and
Handle Extension C-4171-2 (Handle) (1) to press
shaft into rear bearing.
CAUTION: Do not re-use old output shaft nut
because the removed stake weakens the nut
flange. Using Wrenches 6497 and 6498-A, install
new output shaft nut. Tighten new output shaft nut
to 271 Nꞏm (200 ft. lbs.).
18. Check the turning torque (1) of the output shaft.
The shaft should have 1 to 8 in. lbs. of turning
torque. If the turning torque ishigher than8in.
lbs., install a thicker shim. If turning torque isless
than1 in. lb., install a thinner shim. Make sure
there is no end play.

CAUTION: Failure to stake nut could allow the nut
to back-off during use.
19. The new nut (3) must be staked after the correct
turning torque is obtained. Use Staking Tool 6639
(2) to stake output shaft nut.
20. Verify that the nut has been properly staked to the
output shaft.

21. Install low/reverse clutch pack (1, 2). Leave
uppermost disc out to facilitate snap ring
installation.
22. Install low/reverse reaction plate snap ring (2).
23. Install one low/reverse clutch disc (1).
Page 2958 of 5267
24. Install low/reverse reaction plate (1) with flat side
up.
25. Install a new tapered snap ring (2) (tapered side
out).
26. Make sure that the snap ring ends are oriented as
shown.

27. Measure low/reverse clutch pack. Set up Dial Indi-
cator C-3339 (1) as shown. Press down clutch
pack with finger and zero dial indicator. Record
measurement in four (4) places and take average
reading.Low/Reverse clutch pack clearance is
0.84 to 1.60 mm (0.033 to 0.063 inch).
28. Select the proper low/reverse reaction plate to
achieve specifications.
29. Install 2/4 clutch pack (1, 2).
NOTE: The 2/4 Clutch Piston has bonded seals
which are not individually serviceable. Seal
replacement requires replacement of the piston
assembly.
30. Install 2/4 clutch belleville spring (1).
Page 2960 of 5267
31. Verify the proper orientation of the return spring
(2) to the 2/4 retainer (3).
32. Install 2/4 clutch retainer (1).
NOTE: Verify that Compressor 5058A (1) is cen-
tered properly over the 2/4 clutch retainer (4)
before compressing. If necessary, fasten the
5058A bar to the bellhousing flange with any com-
bination of locking pliers and bolts to center the
tool properly.
33. Set up Compressor 5058A (1) as shown. Com-
press 2/4 clutch just enough to facilitate snap ring
installation.
