See Figure 4. Install the sprocket (F) onto differential (C), sliding it over the (4) threaded studs. Start the (4) retaining nuts by hand.
Using a wrench, check to make sure that the screw heads on the opposite side of the differential case are tight. Continuing to hold
a wrench on the screw head, tighten each nut to 10 ft/lbs. torque to retain the sprocket. Again holding each screw head, tighten
all nuts to 15 ft/lbs. torque.
