Turn bearing assembly (14) to make roller fit while tightening nut (13) to a torque of 50 10 lb. ft. (6.9 1.4 mkg)Hold differential and turn gear assembly (12) clockwise two turns and then counterclockwise two turns. Maximum torque needed to turn the gear assembly must be not more than 25 lb. ft. (3.5 mkg)Use the shims (8) as necessary behind the retainer (6) while assemblying to put enough preload on the pinion bearings so the torque needed to turn the bevel pinion shaft (1) is ... 20 5 lb. in.(23.1 5.8 cm.kg)Do not install seal in retainer (6) until after adjustment is complete.Assemble the differential assembly with the center line of the axle in the vertical position and the bearing cone (10) and the cup (9) at the bottom.Turn the adjustment ring (11) to get approximate needed amount of free movement (backlash) between the bevel gear (7) and bevel pinion (1). Make adjustment to the bearing cone (3) and cup (5) to get the maximum preload making so dimension (B) between the bearing cap and the differential assembly does not increase more than ... .007 .002 in.(0.18 0.05 mm)Turn both adjustment rings (2) and (11) the same amount so there is no change of the bearing preload so the amount of free movement (backlash) between the bevel gear (7) and the bevel pinion (1) is ... .014 .002 in.(0.36 0.05 mm)After installing in machine move the stop (4) as necessary to get a clearance (A) between the stop (4) and the right bearing cap to the amount of ... .002 .001 in.(0.05 0.025 mm)(15) Torque for the nuts on the bolts that hold the cases together ... 280 20 lb. ft.(38.7 2.8 mkg) (16) Torque for the nuts that hold the bearing cap to the differential carrier ... 800 100 lb. ft.(110.6 13.8 mkg)(17) Torque for the studs that hold the bearing cap to the differential carrier ... 300 30 lb. ft.(41.5 4.1 mkg)(18) Torque for the nuts that hold the bevel gear to the differential case (with lubricant on the threads) (check by hands) ... 320 10 lb. ft.(44.3 1.4 mkg)
