Install Tooling (B) and a suitable lifting device to pinion housing (1). The weight of pinion housing (1) is approximately 132 kg (290 lb).
Install O-ring seal (4) to pinion housing (1). Lubricate O-ring seal (4) with clean oil.
Install pinion housing (1) to carrier (27).

Ensure that backlash is present before pinion housing (1) is secured to carrier (27). Install bolts (2). Tighten bolts (2) to a torque of 210 40 N m (155 30 lb ft) plus an additional 120 degrees 10 degrees.Note: Steps 58 through 69 are for setting the backlash and the pinion depth.

Move adjusting rings (19) and (23) on carrier (27) to a position that maintains gear backlash and slight bearing end play.

Install yoke (10A) to pinion shaft (10). Install Tooling (K) to yoke (10A). Use a torque wrench to slowly turn pinion shaft (10). Check the overall rolling torque with no load on the carrier bearings. Record the measured torque.
Oscillate the bevel gear and advance adjusting ring (19). Continue to advance adjusting ring (19) until there is no backlash. Retract adjusting ring (19) by 1/2 turn.
Advance adjusting ring (23) and check the rolling torque on pinion shaft (10). Continue to advance adjusting ring (23) until the rolling torque increases by 20 percent over the rolling torque that was measured in Step 59. This is the seated position.
Advance adjusting ring (23) by an additional three lugs. Advance adjusting ring (23) to the nearest lock position.

Typical Example
Mount Tooling (J) on carrier (27). Measure the backlash at four places on the bevel gear at 90 degree intervals. Compare the lowest reading to the specifications. The proper backlash setting is 0.40 0.12 mm (0.016 0.005 inch).
If the backlash is not within the specification, retract one adjusting ring and advance the opposite adjusting ring equally. This will maintain the bearing preload.
When proper backlash is obtained, tighten bearing cap bolts (24) to a torque of 1800 200 N m (1330 150 lb ft).
Use a suitable torque wrench and Tooling (F) to measure the overall rolling torque at the pinion shaft. The rolling torque must be 4.5 N m to 6.7 N m (40 lb in to 60 lb in).

After the backlash adjustment and the preload adjustment have been made, the tooth contact between the pinion shaft and the ring gear must be checked. Use the following procedure:
Put a small amount of Prussian blue, red lead or paint on the teeth of the ring gear.
Rotate the pinion in both directions.
The correct area of tooth contact starts near the inside end of the teeth. The contact area should extend to a maximum of 50 percent of the length of the teeth. See Illustration 40 for the correct area of tooth contact.
