Removal and InstallationEDS002JK
REMOVAL
1. Remove the drive shaft inside flange bolts to disconnect the rear drive shafts from the rear final drive.
Support the rear drive shafts using suitable wire.
NOTE:
Disconnecting the rear drive shafts is necessary to measure the total preload accurately.
2. Remove the rear propeller shaft. Refer to PR-8, "
Removal and Installation" .
CAUTION:
Do not damage the propeller shaft tube.
3. Check the total preload. Refer to RFD-12, "
TOTAL PRELOAD" .
4. Put a mark on the end of the drive pinion corresponding to the
position mark “B” on the companion flange as shown.
CAUTION:

Use paint to make the matching mark “B” on the drive
pinion. Never damage the drive pinion.

The mark “B” on the companion flange indicates the
maximum vertical runout position.
5. Remove drive pinion nut using Tool as shown.

Discard the drive pinion nut and use a new drive pinion nut for

4. Install drive pinion nut using Tool.

Tighten the drive pinion nut to the minimum specified torque.
Final drive pinion nut torque will be determined when adjust-
ing the total preload. Refer to RFD-12, "
TOTAL PRELOAD" .
CAUTION:
The drive pinion nut is not reusable. Use a new drive pinion
nut for installation.
5. Install the rear propeller shaft. Refer to PR-8, "

REMOVAL
1. Remove the drive shaft inside flange bolts to disconnect the rear drive shafts from the rear final drive.
Support the rear drive shaft using a suitable wire.
2. Remove the side flange using Tools as shown.
a. Install Tool “A” on the side flange.
b. Pull the side flange out using Tool “B” as shown.
3. Remove the side oil seal using a suitable tool as shown.
INSTALLATION
1. Apply multi-purpose grease to the sealing lips of the side oil seal.
2. Press-fit the new side oil seal using Tool, until the front surface
of the side oil seal is level with the end surface of the housing.
CAUTION:

Keep the side oil seal even when installing, do not tilt the
side oil seal when pressing it in.

Discard the old side oil seal, always install a new side oil
seal.
3. Install the side flange using Tool.
a. Attach Tool to the side oil seal as shown.
b. After the side flange is inserted and the serrated part of the side
gear has engaged the serrated part of the flange, remove Tool.
c. Position a suitable drift on the center of the side flange, then
drive it in until the sound changes.
NOTE:
When the installation is complete, the driving sound of the side
flange turns into a sound which seems to affect the whole final
drive.Tool number A: KV40104100 ( — )

Revision: August 20072004 QX56
CAUTION:
Final drive pinion nut torque will be determined when adjusting the total preload. Refer to RFD-12,
"TOTAL PRELOAD" .
Pre-InspectionEDS002JO
Before disassembling the rear final drive, perform the following inspections.
TOTAL PRELOAD
1. Turn the drive pinion in both directions several times to set the
bearing rollers.
2. Check the total preload using Tool.
DRIVE GEAR TO DRIVE PINION BACKLASH
Check the drive gear to drive pinion backlash using a dial gauge at
several points as shown.
DRIVE GEAR RUNOUT
Check the runout of the drive gear using a dial gauge as shown.
