Usage:
Disassemble Torque Proportioning Differential
1. Fasten a hoist and remove the differential from the carrier. The weight of the differential is:
- 920-65 lb. (29 kg)930-95 lb. (43 kg)
2. Remove the lockwire and bolts (2) from each end of the differential to remove covers (3). Remove bearings (1) from the covers only when replacement parts are needed.
3. Remove discs (4) and springs (5) from each end of the differential case. Make a note of the position of the springs for assembly purposes.
4. Remove gears (6) from each end of the differential case.
5. Remove rings (7) from each end of the differential case.
6. Remove pins (8) from the differential case.
7. Use a 1/4"-20 NC forged eyebolt to remove the twelve shafts (9).
8. Remove the twelve pinion gears and eight wear plates (for the center pinion gears) from the differential case.
Assemble Torque Proportioning Differential
NOTE: There are eight drive pinions (1) with the same part number. There are four idler pinions with the same part number.
NOTICE |
---|
Install the pinions so the end of the pinions that have the identification mark is toward the inside of the differential case. |
1. Install four idler pinions (2) in the center of case (3). Install wear plates (4) in the case. Install the four shafts (5) for the idler pinions.
2. Install four drive pinions (1) in the end of the case opposite the flange. Install shafts (5) for the drive pinions.
3. Install four drive pinions (1) in the end of the case with the flange. Install shafts (5) for the drive pinions.
4. Put the holes in the shafts in alignment with the holes in the case and install pins (6) to hold the shafts.
5. Install ring (7) in the grooves in the differential case.
6. Install gears (8) in each end of the differential case.
7. Put oil on both sides of springs (10) and install them so that the outside diameters make contact with the gear first.
8. Heat the bearings to a maximum temperature of 275°F (135°C) and install them on covers (11).
9. Put 5P960 Multipurpose Type Grease on both sides of discs (9) and install the discs on covers (11).
10. Put covers (11) in position and install the bolts and lockwire to hold the covers.
11. Fasten a hoist and install the differential in the carrier.
