(1) Torque for the nuts that hold the bearing caps to the carrier ... 640 80 lb ft(865 110 N m)(2) Torque for the studs that hold the bearing caps to the carrier ... 240 20 lb ft(320 25 N m)(3) Torque for the nuts that hold the bevel gear to the differential case (with lubricant on threads and tightened by hand) ... 265 10 lb ft(360 14 N m)(9) Torque for the nuts that hold the cases together ... 220 10 lb ft(295 14 N m)Adjustment For The Differential And Bevel Gear:
1. Install the bearings on pinion (4) and install pinion (4) in the carrier.2. Use shims (12) as necessary behind retainer (10) to put enough preload on the pinion bearings so the torque needed to turn pinion (4) is ... 20 5 lb in(2.3 .06 N m) Do not install the seal in retainer (10) until after the adjustment is made. Turn the pinion slowly while making the adjustment.3. Install gears (5) in the differential case. Turn the gears. The torque needed to turn gears (5) must not be more than ... 25 lb ft(35 N m)4. Install the differential assembly in the carrier. Put the carrier in a position so the centerline for the axle is vertical and adjustment ring (6) is down. FOR TORQUE VALUES NOT GIVEN, SEE THE FIRST PAGE OF SPECIFICATIONS FOR GENERAL TIGHTENING TORQUES. 5. Install the bearing caps.6. Turn adjustment ring (6) to get approximate amount of free movement (backlash) between bevel gear (11) and pinion (4).7. Using a dial indicator, measure the amount of change in dimension (B). Turn adjustment ring (13) to get the maximum preload on carrier bearings until dimension (B) has an increase of ... .007 .002 in(0.18 0.05 mm).8. Using a dial indicator, measure the backlash between bevel gear (11) and pinion (4). Turn adjustment rings (6) and (13) the same amount and in the same direction until the backlash is ... .014 .005 in(0.36 0.13 mm). If the adjustment rings are turned like this, there will be no change in the preload of the bearings.9. After installing the differential in the machine, remove the cover from the top of the differential housing. Loosen nut (8) and turn stop (7) so clearance (A) between stop (7) and the bearing cap is ... .002 .001 in(0.05 0.03 mm)10. Tighten nut (8) and install the cover.
