ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
5. 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.

After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.

If measured value is out of the specification, remove final
drive assembly and disassemble drive pinion parts to check
and adjust each part. Refer to FFD-13, "

If the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.
Refer to FFD-36, "
Pinion Height Adjusting Washer" .

If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.
Refer to FFD-36, "
Pinion Height Adjusting Washer" .
Backlash
1. Remove carrier cover. Refer to FFD-20, "Differential Assembly" .
2. Fit a dial indicator to the drive gear face to measure the back-
lash.

If the backlash is outside of the specified value, change the
thickness of side bearing adjusting washer.
Companion Flange Runout
1. Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate companion flange to check for runout.
3. Fit a test indicator to the inner side of companion flange (socket
diameter).
4. Rotate companion flange to check for runout.
5. If the runout value is outside the runout limit, follow the proce-
dure below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion by 90° step, and
search for the position where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, possible cause will be an
assembly malfunction of drive pinion and pinion bearing and malfunction of pinion bearing. Check for
these items and repair if necessary.
