RING-RETAINING 1775241 - Caterpillar

Use Tooling (C) with a dial type torque wrench in order to set the rotating torque. Tighten nut (22) in order to achieve a rotating torque of 1.81 to 2.60 N m (16.0 to 23.0 lb in).
Illustration 11 g01032416
Use a suitable hammer and a punch and stake nut (22) .
Illustration 12 g01032369
Install thrust washer (20) and side gear (21). Install spider (19), gears (18), and thrust washers (17) .
Illustration 13 g01032576
Install planetary shafts (16). Install locking pins (15). Install side gear (14) and thrust washer (13). Install cover (12) .
Illustration 14 g01034446
Raise the temperature of bearing cones (8) and (9). Install bearing cones (8) and (9) .
Illustration 15 g01034447
Install bevel gear (11) onto the differential. Apply Tooling (K) to the threads of bolts (10). Install bolts (10) and tighten bolts (10) to a torque of 70 N m (52 lb ft).
Illustration 16 g01032317
Install bearing cups (6) and (7) and install the differential into the axle housing.
Illustration 17 g01032081
Install caps (5) and install bolts (4). Slightly tighten bolts (4). Do not torque bolts (4) at this time.
Illustration 18 g01034579
Use Tooling (A) and install spanner nuts (3) .
Oscillate the pinion shaft and use Tooling (A) to advance spanner nuts (3) until there is slight backlash and no end play on the bearings.
Illustration 19 g01032416
Use a dial type torque wrench and measure the total rotating torque. Use the following formula in order to calculate the total rotating torque (TRT): P equals the rotating torque that was measured in Step 13. TRT = P + 0.280 N m (2.48 lb in) to P + 0.467 N m (4.13 lb in)
If the total rotating torque (TRT) is less than the specified amount, tighten the spanner nuts. If the total rotating torque (TRT) is greater than the specified amount, loosen the spanner nuts. Be sure to always maintain a slight backlash.
Illustration 20 g01034591
Mount Tooling (L) onto the differential housing, as shown. Measure the backlash between the pinion and the bevel gear. The proper backlash setting is 0.180 to 0.230 mm (0.0071 to 0.0091 inch).
Illustration 21 g01029595
If the backlash is not within the specification, retract one spanner nut and advance the opposite spanner nut equally. This will maintain the bearing preload. If the backlash is less than the specified amount, move the bevel gear in Direction (A). If the backlash is greater than the specified amount, move the bevel gear in Direction (B) .
Illustration 22 g01032077
Install retainers (2) and bolts (1). Tighten bolts (1) to a torque of 13 N m (10 lb ft).
Illustration 23 g01034820
Tighten bolts (4) to a torque of 266 N m (196 lb ft).End By: Install the rear axle differential and bevel gear into the axle housing. Refer to Disassembly and Assembly, "Axle Housing (Differential and Bevel Gear) (Rear) - Install".
