1. Check to make sure flange of case and contacting surface of gear are clean and free of burrs. 2. Heat the bevel gear to a maximum temperature of 250°F (120°C). Install the bevel gear (4) on differential case (3).3. Put oil on the threads of bolts (1) and on face of washers (2) that hold gear to case. Install the bolts, washers and locks. Tighten all bolts the same amount until they have a torque of 98 9 lb.ft. (134 12 N m). Make a bend in the locks.4. If original bevel gear and cases are being used again, the dowels must fit tight in both the gear and the case. If the dowels do not fit tight, remove them. Install the larger service dowels using procedure in Step 5. 5. If a new bevel gear and/or cases are being installed, install the larger service dowels using following procedure: a) Make the original dowel holes (5) larger by using a .844 in. (21.4 mm) drill or a .875 in. (22.2 mm) core drill.b) Again, make the dowel holes larger by line reaming them to a diameter of .9045 to .9055 in. (22.9743 to 22.9997 mm). Use a standard .906 in. (23.1 mm) reamer to do this. c) Install the three service dowels (6) even with face of differential case (3). 6. Put oil on spider and pinion components. Install the thrust washers and side gear (7) in differential case (3) with the oil groove in thrust washer next to the side gear.
Make a replacement of the thrust washers for the side gears and the thrust washers for the pinions as a set.
7. Install the cup thrust washers (10) and pinions (8) on spider (9).8. Put the spider (9) in position in differential case (3). 9. Install side gear (12) and thrust washer (11) with groove in washer next to the gear. 10. Put differential case (13) into position on case (3) with the marks on each case in alignment with each other. Install bolts (14).
