FRONT INSULATORS
NOTE: If a new rear insulator is also to be in-
stalled, it should be installed first since the engine
locates from the rear insulator.
1. Raise hood and, using J 22603 engine lifting
tool, (Fig. 6-74), take weight of engine off front

fore raising engine. When engine is raised, the
starting motor solenoid terminals may contact the
steering gear which could energize the starting
motor if ground cable is not disconnected.

engine.

4. Raise engine just clear of insulator.
5. Remove insulator.

stall attaching screws and washers. Tighten to 70
lb. ft. torque.
7. Lower engine.

and plain washer and tighten to 50 lb. ft.
weight from rear insulator, using suitable lifting
equipment.

sulator lower retainer cross member support nut
and raise transmission until retainer stud is dis-
engaged from lower cross member support.

retainer bolts from transmission extension.

tension and cross member support.
