TRANSFER ASSEMBLY
●When installing the transfer to the transaxle, install the mounting
bolts following the standard below.
CAUTION:
When installing the transfer to the transaxle, be careful not
to damage the oil seals.
●When installing transfer gusset, tighten mounting bolts to the following torque (vehicles with YD22ET
engine only):
●After the installation, check the oil level and oil leakage.

3. Using a preload gauge, measure the preload torque of the pin-
ion bearing.
CAUTION:
Every rotational part shall rotate smoothly with the speci-
fied gear oil.
●If outside the standard, disassemble the pinion sleeve assem-
bly to check and adjust each part.
Overall preload torque
1. Measure pinion bearing preload torque (P1 ).
2. Install the pinion sleeve shims and pinion sleeve assembly.
3. Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
4. Using a preload gauge, measure the overall preload torque.
●If outside of the standard, disassemble it to check and adjust
each part. If measuring the overall preload torque after the disassembly, measure it with the transfer
case oil seals and gear ring oil seals removed, then install the oil seals.
COMPANION FLANGE RUNOUT
1. Fit a dial gauge onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate the companion flange to check for runout.
3. Fit a test indicator to the inner side of the companion flange
(socket diameter).
4. Rotate the companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. While changing the phase between companion flange and drive pinion gear by 90° at a time, check runout
and determine which phase angle minimizes the runout.
b. If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c. If the runout is outside the standard after the companion flange is replaced, adjust the assembly status of
the pinion bearings and drive pinion gear, or replace the pinion bearings. Preload torque

INSPECTION AFTER DISASSEMBLY
Gears
●Check the gear faces and shaft for wear, cracks, damage, and seizure.
CAUTION:
If a malfunction is detected on the drive gear or drive pinion gear, replace the drive gear and drive pin-
ion gear as a set.
Bearings
●Check for seizure, peeling, wear, corrosion, sticking/abnormal noise/roughness in hand turning, and other
damage.
CAUTION:
When replacing the bearing, always replace the inner race and outer race as a pair.
Washers and shims
●Check for seizure, damage, and abnormal wear.
Oil seals
●Discard old oil seals; replace with new ones.
●If wear, deterioration of adherence (sealing force of lips), or damage is detected on the lips, replace them.
