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 an assembly malfunc-
tion of drive pinion and pinion bearing and malfunction of pin-
ion 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 – 0.4
N·m (0.01 – 0.04 kg-m) to
the measured value when
removing.
