1.

Select drive pinion adjusting shim. Refer to 

DLN-91, "CVT : Adjustment"

.

2.

Install selected drive pinion adjusting shim to drive pinion.

3.

Install inner race of drive pinion bearing (front side) to drive pin-
ion with a drift (A) (SST: ST23860000).

CAUTION:

• Never reuse drive pinion bearing (front side).
• Apply gear oil to the drive pinion bearing (front side).

4.

Assemble the inner race of drive pinion bearing (rear side) into
the transfer case.

CAUTION:

• Never reuse drive pinion bearing (rear side).
• Apply gear oil to the drive pinion bearing (rear side).

5.

Install drive pinion oil seal to transfer case with drifts so that it
becomes flush with case end surface.

CAUTION:

• Never reuse oil seal.
• Apply multi-purpose grease onto oil seal lips, and gear oil

onto the circumference.

6.

Assemble a collapsible spacer onto the drive pinion.

CAUTION:

Never reuse the collapsible spacer.

7.

Assemble drive pinion assembly into the transfer case, and then
install companion flange (1) to drive pinion.
NOTE:

8.

Tap the companion flange with a plastic hammer as far as the
lock nut can be tightened.

CAUTION:

Never damage drive pinion oil seal.

9.

Apply anti-corrosive oil to the thread and seat of the lock nut,
and temporarily tighten lock nut to the drive pinion.

CAUTION:

Never reuse lock nut.

10. Tighten lock nut within the specified torque range with a preload

gauge (A) (SST: ST3127S000) so that the drive pinion bearing
preload is within standard.

CAUTION:

• Start the tightening of lock nut from lower limit of the

specified torque. Check the preload every 5

°

 to 10

°

 while

tightening the lock nut.

• Replace the collapsible spacer and tighten it again to adjust if preload exceeds the specified

value. Never loosen lock nut to adjust preload.

• After adjustment, rotate the drive pinion back and forth from 2 to 3 times to check for unusual

noise, sticking, binding, and so on.

11. Install ring gear shaft assembly. Refer to 

DLN-73, "CVT : Assembly"

.

12. Install adapter case. Refer to 

DLN-65, "CVT : Assembly"

.

13. Check backlash, tooth contact, total preload and companion flange runout. Refer to 

DLN-91, "CVT :

Adjustment"

.

CAUTION:

Measure the total preload without the adapter case oil seal.
