DLN

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.

Tighten to drive pinion lock nut, while adjust total preload torque.

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.

Set a dial indicator (A) vertically to the tip of the drive pinion.

Rotate drive pinion to check for runout.

• If the runout value is still outside of the limit after the phase

has been changed, possible cause will be an assembly mal-
function of drive pinion and pinion bearing and malfunction of
pinion bearing. Check for these items and repair if necessary.

Make a stamping for identification of front oil seal replacement frequency. Refer to “Identification stamp of
replacement frequency of front oil seal”.

CAUTION:

Never make a stamping after replacing front oil seal.

Install propeller shaft. Refer to

DLN-93, "Removal and Installation"

10. Install side flange with the following procedure.

Attach the protector [SST: KV38107900 (J-39352)] to side oil
seal.

After the side flange is inserted and the serrated part of side
gear has engaged the serrated part of flange, remove the pro-
tector.

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 which seems to affect the whole final drive.

A: Preload gauge [SST: ST3127S000 (J-25765-A)]

Total preload torque

: Total preload torque
should equal the measure-
ment taken during removal
plus an additional 0.1 – 0.4
N·m (0.01 – 0.04 kg-m, 1 – 3
in-lb).
