- Select the 35 mm thrust shim if the tapered roller bearing on the transfer output shaft is replaced. Measure the thickness of the replacement bearing and the existing bearing, and calculate the difference of the bearing thickness. Adjust the thickness of the existing 35 mm thrust shim by the amount of the difference in bearing thickness, and select the replacement 35 mm thrust shim from the table.
- Install the 35 mm thrust shim (A) on the transfer output shaft (B), then install the tapered roller bearing (C) with the special tools and a press.
- Place the tapered roller bearing (A) on the bearing outer race of the companion flange side of the transfer housing.

- Install the transfer output shaft (A) in the transfer housing (B). Do not install the transfer spacer on the transfer output shaft.
- Install the companion flange (A), conical spring washer (B), and locknut (C) on the transfer output shaft (D). Do not install the O-ring and back-up ring.
- Secure the transfer housing (A) in a bench vise (B) with soft jaws. To prevent damage to the transfer housing, always use soft jaws or equivalent materials between the transfer housing and the vise.
- Install the special tool on the companion flange.
- Tighten the locknut while measuring the starting torque so the starting torque is within 0.98-1.39 N.m (10.0-14.2 kgf.cm, 8.7-12.3 lbf.in.). Do not stake the locknut in this step.
- Install the transfer shaft (A) in the transfer holder (B), and install the transfer drive gear (C), transfer collar (D), 25 mm thrust shim (E), tapered roller bearing (F), conical spring washer (G), and locknut (H).

- Set a dial indicator (A) on the companion flange (B).
- Measure the transfer gear backlash. Standard: 0.06-0.16 mm (0.02-0.06 in.)
- Remove the transfer holder, and check the transfer drive gear tooth contact pattern.
- If the backlash measurement is out of standard, adjust the backlash with the 35 mm thrust shim and recheck. Do not use more than two 35 mm thrust shims to adjust the backlash.
- If the transfer gear tooth contact is incorrect, adjust the tooth contact with the 25 mm or 35 mm thrust shim. Do not use more than two of each thrust shim to adjust the tooth contact. Toe Contact Use a thicker 35 mm thrust shim to move the transfer output shaft toward the transfer drive gear. Because this movement causes the transfer gear backlash to change, move the transfer drive gear away from the transfer output shaft to adjust the transfer gear backlash as follows: Increase the thickness of the 25 mm thrust shim. Reduce the thickness of the 68 mm thrust shim by the amount you increased the 25 mm thrust shim. Heel Contact Use a thinner 35 mm thrust shim to move the transfer output shaft away from the transfer drive gear. Because this movement causes the transfer gear backlash to change, move the transfer drive gear toward the transfer output shaft to adjust the transfer gear backlash as follows: Reduce the thickness of the 25 mm thrust shim. Increase the thickness of the 68 mm thrust shim by amount you reduced the thickness of the 25 mm thrust shim. Flank Contact Use a thinner thrust shim to move the transfer drive gear toward the transfer output shaft. Flank contact must be adjusted within the limits of the transfer gear backlash. If the backlash exceeds the limits, adjust as described under Heel Contact. Face Contact Use a thicker thrust shim to move the transfer drive gear away from the transfer output shaft. Face contact must be adjusted within the limits of the transfer gear backlash. If the backlash exceeds the limits, adjust as described under Toe Contact.
