@ Make sure tifts, iacks, and satety stands
are placed properly (see section 1).
L Raise the front of the vehicle, and support it with
safety stands (see section 1).
2. Set the parking brake, and block both rear wheels
securely.
3. Shift to neutral oosition.
4. Make a reference mark across the DroDeller shaft

1.lf the measurement is out of specification, remove
the transfer assembly and adjust transfer gear back-
lash (see page 13-44 thru '13-61).
Check the transfer oil seal for damage and fluid
teaKs.
lf oil seal replacement is required, remove the trans-
fer assembly, replace the oil seal, and adjust the
total starting torque (see page 13-44 thru 13-61).
NOTE: Do not replace the oil seal when the transfer
assembly is installed on the transmission.

Tapered Roller Bearing Preload Adiustment
lf any oJ the items listed below were replaced, the tapered
roller bearing preload must be adjusted.
. Transmission housing
. Clutch housing
. Differential carrier
o Tapered roller bearing and bearing outer race
. Thrust shim
. 75 mm sham
1. Remove the bearing outer race and thrust shim
from the transmission housing (see page 13-40)'
NOTE:
. Do not reuse the thrust shim if the bearing outer
race was driven out.
. Let the transmission cool to room temperature il
the bearing outer race was removed by heating
the clutch housing.
2. Do not use more than one thrust shim to adjust the
tapered bearing preload. First try the same size
thrust shim that was removed. There are no shims
used on the clutch housing side
SHIMTHRUST
/A
After installing the thrust shim, install the bearing
outer race in the transmission housing (see page
13-40).
With the mainshaft and countershaft removed,
install the differential assembly, and torque the
clutch housing and transmission housing.
NOTE: lt is not necessary to use sealing agent be-
tween the housings.

of the differential assembly in both directions with
the special tool and a torque wrench.

Transfer Assembly
Reassembly
Note these items during reassembly:. While reassembling the transfer assembly:- Check and adjust the transfer gear tooth contact.- Measure and adjust the transfer gear backlash.- Check and adjust the tapered roller bearing start-Ing rorque.
. Coat all parts with MTF during reassembly.. Replace the tapered roller bearing and the bearingouter race as a set if either part is replaced.. Replace the transfer drive gear and the transfer dri-ven gear shaft as a set if either part is replaced,
Outline of Assembly
1.Select the 35 mm thrust shim.
Perform this procedure if the transler driven gear
shaft or the tapered roller bearing on the transferdriven gear shaft is replaced.
Preassemble the parts to check and adjust transfergear backlash and transfer gear tooth contact.
Disassemble the parts, then assemble the transferdriven gear shaft and its related parts.
4. Measure and adjust the staning torque of the trans-fer driven gear shaft tapered roller bearing.
5. Assemble the transfer shaft and jts related parts.
6. Measure and adjust the total starting torque.
35 mm Thrust Shim Seleqtion
1. Select the 35 mm thrust shim if the transfer drivengear shaft or the tapered roller bearing on the trans-fer driven gear shaft is replaced.
Calculate the thickness of the 35 mm thrust shimusing the formula below.

7.Secure the transfer housing in a bench vise with
soft jaws, then install the special tool on the com-
panion flange. To prevent damage to the transfer
housing, always use soft jaws or equivalent materi-
als between the transfer housing and the vise.

8. Tighten the locknut while measuring the starting
torque so the starting torque is within 0.98 - 1.39

NOTE:
. Coat the threads of the locknut, and the shaft
with MTF before installing the locknut.
. Do not stake the locknut in this step.
