ing the differential case cover to about 212°F (100°C).

NOTE:

• Do not heat the differential case cover in excess

of 212°F (100°C).

• If the bearing outer race was removed by heat-

ing, allow the differential case cover to cool to

room temperature.

• Replace the tapered roller bearing with a new

one whenever the bearing outer race is replaced.

Rocker Arm Assembly

Removal

1. Loosen the adjusting screws, then remove the bolts

and the rocker arm assembly.

NOTE:

• Unscrew the camshaft holder bolts two turns at a

time, in a crisscross pattern, to prevent damaging

the valves or rocker arm assembly.

• When removing the rocker arm assembly, do not

remove the camshaft holder bolts. The bolts will

keep the camshaft holders, the springs and the

rocker arms on the shafts.
