5. Install outer race of pinion bearing (front) to the transfer case
with the drift (A) [SST: ST37830000 (
—
)].
CAUTION:
• Never reuse pinion bearing.
• Apply gear oil to the pinion bearing.
6. Install outer race of pinion bearing (rear) to transfer case with
the drift (A) [SST: ST33230000 (J-25805-01)].
CAUTION:
• Never reuse pinion bearing.
• Apply gear oil to the pinion bearing.
7. Install drive pinion assembly to transfer case. Refer to
.
8. Install ring gear shaft assembly to transfer case. Refer to
.
9. Set the drifts (A and B) to right and left side spacers individually.
Compress ring gear shaft assembly with ring gear bearing to
install transfer cover to transfer case.
CAUTION:
• Never apply gasket fluid on the mounting surface.
• Clean the mounting surface of transfer case and transfer
cover to degrease sufficiently.
• The drift shall be placed on the center of the spacers.
• The pressure shall be as low as to install ring gear shaft
assembly into transfer case. The maximum pressure shall be 10 kN (1 ton, 1.0 Imp ton).
• If the adjusting shims and spacers are installed by tapping, the transfer cover may be damaged.
Avoid tapping.
10. Check backlash, tooth contact, and total preload. Refer to
CAUTION:
Measure the total preload without the transfer case oil seals.
11. Remove transfer cover. Refer to
.
12. Apply liquid gasket (1) to mating surface of transfer cover.
• Use Genuine Silicone RTV or equivalent. Refer to
"Recommended Chemical Products and Sealants"
