6.
Install attachment (A) [SST: KV40104100 (
—
)] to side
flange, and then pull out the side flange with the sliding hammer
(B) [SST: ST36230000 (J-25840-A)].
NOTE:
Circular clip installation position: Final drive side
7.
Remove propeller shaft. Refer to
8.
Measure the total preload with the preload gauge (A) [SST:
ST3127S000 (J-25765-A)].
NOTE:
Record the preload measurement.
9.
Put matching mark (B) on the end of the drive pinion. The
matching mark (B) should be in line with the matching mark (A)
on companion flange (1).
CAUTION:
For matching mark, use paint. Never damage companion
flange and drive pinion.
NOTE:
The matching mark (A) on the final drive companion flange (1)
indicates the maximum vertical runout position.
10. Remove drive pinion lock nut using the flange wrench.
11. Remove companion flange using pullers.

4.
Apply anti-corrosion oil to the thread and seat of new drive pin-
ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Never reuse drive pinion lock nut.
5.
Tighten drive pinion lock nut within the limits of specified torque
so as to keep the pinion bearing preload within a standard val-
ues.
CAUTION:
• Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
• If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
6.
Set a dial indicator (A) vertically to the tip of the drive pinion.
7.
Rotate drive pinion to check for runout.
• If the runout value is still outside of the limit after the phase
has been changed, possible causes are be an assembly mal-
function of drive pinion and pinion bearing and malfunction of
pinion bearing. Check for these items and repair if necessary.
8.
Make a stamping for identification of front oil seal replacement frequency. Refer to “Identification stamp of
replacement frequency of front oil seal”.
CAUTION:
Make a stamping after replacing front oil seal.
9.
Install propeller shaft. Refer to
10. Install side flange with the following procedure.
a.
Attach the protector [SST: KV38107900 (J-39352)] to side oil
seal.
b.
After the side flange is inserted and the serrated part of side
gear has engaged the serrated part of flange, remove the pro-
tector.
c.
Put a suitable drift on the center of side flange, then drive it until sound changes.
NOTE:
When installation is completed, driving sound of the side flange turns into a sound that seems to affect the
whole final drive.
A: Preload gauge [SST: ST3127S000 (J-25765-A)]
Total preload torque
: A value that add 0.1 –
0.4N·m (0.01– 0.04 kg-m) to
the measured value when
removing.
