8. Move driveshaft up and down to determine end
play. Total up and down movement should be
0.00″ to 0.001″ (0.025mm). There should be no
preload on the bearing and the driveshaft must
rotate freely.
NOTE: DO NOT change shims under upper bearing
cup or pinion height will be changed.
9. Maintain the shims as previously set under the
upper driveshaft bearing cup.
10. Remove the upper bearing cup retainer with tool
91-43506, and remove cup [leave upper cup
shim(s) in place].
NOTE: A 0.001
″
(.025mm) change of shims under
the lower bearing cup will result in a 0.001
″
(0.025mm) change in driveshaft end play.
11. Place driveshaft end play shim(s), determined
from step 8, into gear housing and reinstall the
lower bearing cup.

12. Clean threads of driveshaft and apply Loctite
#271.
13. Apply gear oil to all bearing surfaces and install
driveshaft assembly, upper bearing cup and
retainer into the gear case. Tighten upper cup
retainer to a torque of 100 lb. ft. (135.5 N·m).
NOTE: If forward gear backlash has not yet been
determined, do not use a new pinion nut until final
assembly.
14. Apply #271 Loctite to a NEW pinion nut and install
the pinion gear, washer and nut using procedures
detailed earlier in this section. Tighten pinion nut
to a torque of 85 lb. ft. (115 N
.
m).
15. Rotate driveshaft a few turns to verify that it turns
freely and recheck driveshaft end play.
Clutch Actuator Rod
REASSEMBLY/SHIMMING (STD. GEAR CASE)
NOTE: V-6 models 135 thru 200 SN 0D044293 and
ABOVE gear cases will have only ONE compression
spring.
NOTE: High Performance (CLE) gearcases have 2
compression springs in clutch actuator. See
reassembly/shimming procedure for those gear
cases.
1. Place a small amount of Quicksilver 2-4-C
w/Teflon Lubricant on locating pin.

2. Position pin in cross-hole in end of clutch actuator
rod with flat side of pin toward shim washer.
3. Insert Cross Pin Tool (91-86642) between
compression spring in elongated slot in clutch
actuator rod.
4. Compress spring by forcing cross pin tool
back-and-forth in elongated slot. This will release
any initial set from spring.
NOTE: Single spring actuators DO NOT require
shimming the spring to center the clutch cross pin.
