Section 7.Component Procedures Drive and Brake Drive Unit

Helical Gear/Spiral Pinion Gear Assembly

NOTE: The pinion shaft and bevel gear are a matched set. Their alignment is critical. Do not replace them separately.

Bearing can become extremely hot. Use gloves to protect hands from burns.

1.Preheat the bearing cone with a bearing heater. See Figure7-75 .

NOTE: Steps 2 thru 5 need to be completed before the bearing cools to provide a correct installation.

2.Install the heated bearing cone in the bearing cup in the housing.

3.Place the spacer over the bearing cone, then place the helical gear into the housing.

4.Install the spiral pinion gear shaft up through the helical gear. Push up until the spiral gear bearing is seated against its race. See Figure7-77

6.When the bearing has cooled, spin the helical gear to check for end play. Remove any end play in the bearings between the helical gear and the spiral gear using a nut driver tool (P/N 761-870/T04) and a wedge. Slowly tighten the clamp nut on the end of the spiral gear until there is no end play between the gears. Use a spin and tighten method to tighten clamp nut as the bearings are seating in the races. See Figure7-79.

5.Apply 3 vertical lines of thread-locking compound (P/N 990-669) to the pinion shaft. Place the clamp nut on the end of the spiral pinion gear shaft and hand tighten until the bearing cools. See Figure7-78 .

7.Tighten the clamp nut the distance of a spanner nut space to preload the gears.

8.Back the nut off, then hand tighten.

9.Apply thread-locking compound (P/N1013829) to the screw in the clamp nut. Torque the screw to 128 in. lbs. (14.5Nm). See Figure7-80 .
