PINION BEARING PRELOAD

CAUTION:

When measuring preload, the rotating speed must be set to 30 rpm.
1.

Remove ring gear shaft assembly from the transfer case. Refer to

DLN-83, "Disassembly"

Rotate the companion flange back and forth from 2 to 3 times to check for unusual noise, binding, sticking,
and so on.

Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

Measure the pinion bearing preload using Tool (A).

CAUTION:

Each rotational part should rotate smoothly with the speci-
fied transfer oil.
• If outside the standard, disassemble the drive pinion assembly

to check and adjust each part.

TOTAL PRELOAD

CAUTION:

When measuring preload, the rotating speed must be set to 30 rpm.

to the latest parts information.

CAUTION:

If no adjusting shim with the calculated value is available,
select the thicker and closest one.

• Thicken the drive pinion adjusting shim to move the drive pin-

ion closer to the ring gear in case of face contact or heel con-
tact.

CAUTION:

Only one adjusting shim can be selected.

COMPANION FLANGE RUNOUT

Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).

Rotate the companion flange to check for runout.

Fit suitable tool to the inner side of the companion flange (socket
diameter).

Rotate the companion flange to check for runout.

Follow the procedure below to adjust if runout value is outside
the repair limit.

Check for runout while changing the phase between companion
flange and drive pinion in 90

steps. Then search for the mini-

mum point.

Replace companion flange if runout value is still outside the limit
after the phase has been changed.

Adjust assembly status of the pinion bearing and drive pinion, or
replace pinion bearing assembly if runout is outside the standard
after the companion flange is replaced.
