BOLT 1990647 - Caterpillar

Illustration 13 g00332261
Install yoke assembly (17).
Illustration 14 g00332260
Install yoke retainer (16) and bolt (15) on the output shaft. The torque for bolt (15) is 240 40 N m (177 30 lb ft).

Lower the temperature of bearing cup (13). Install bearing cup (13) in the output transfer gear housing.
Illustration 16 g00334223
Heat bearing cones (12) to a maximum temperature of 135°C (275°F). Install one bearing cone (12) on each side of input transfer gear (11).
Illustration 17 g00334227
Install input transfer gear (11), as shown.

Lower the temperature of bearing cup (9). Install bearing cup (9) in bearing cage assembly (6). Do not install O-ring seal (10) at this time.
Illustration 19 g00334230Note: The bearing axis must be vertical for correct end play adjustment.
Use a 0.038 mm (0.0015 inch) shim or a standard feeler gauge to ensure that the bearing cups and the bearing cones are seated in the housing.Note: Do not install the O-ring seal or the shims at this time.
Use two cage bolts (5) in order to install bearing cage assembly (6). The cage bolts are separated by 180 degrees.
Tighten two cage bolts (5) to a torque of 1.7 N m (15 lb in).
Turn input transfer gear (11) for at least three revolutions in order to seat the bearings.
Tighten two cage bolts (5) to a torque of 3.4 N m (30 lb in).
Turn input transfer gear (11) for at least three revolutions in order to seat the bearings.
Tighten two cage bolts (5) again to a torque of 3.4 N m (30 lb in).
Measure the gap between the case and bearing cage assembly (6) at two cage bolts (5). Perform the measurement between the outside diameter of the flange and the cage bolts.
Average the two measurements from Step 40. Add 0.23 mm (0.009 inch) to the average. This result is the required thickness of the shims.
Remove bearing cage assembly (6). Install the O-ring seal on bearing cage assembly (5). Apply clean transmission oil to the O-ring seal. Install bearing cage assembly (6) with the required shims from Step 41. Install cage bolts (5). The torque for cage bolts (5) is 60 12 N m (44 9 lb ft).
Use Tooling (B) to measure the bearing end play. If the bearing end play is less than 0.05 mm (0.002 inch), add shims. If the bearing end play is more than 0.15 mm (0.006 inch), remove shims.

Use the following procedure to install speed sensors (1):
Align the gear tooth with the center of the hole for the transmission speed sensor.
Apply 5P-3413 Pipe Sealant to the threads of the sensor. Install the sensor. Screw the sensor inward until the sensor contacts the gear tooth.
Back off the sensor by 1/2 turn. Tighten the adjustment locknut. The torque for the adjustment locknut is 25 5 N m (18 4 lb ft).Note: Do not allow the sensor to turn as the adjustment locknut is tightened.End By:
