13.Install bushing (10) into rear of the housing with tool group (B) .


Illustration 13 g00810478


Illustration 14 g00810222

14.Install the O-ring seal on the back of the starting motor housing. Put washer (9) on the back of the armature. Put rear housing (6) in position on the starting motor housing. Install bolts (7) and tighten the bolts to a torque of 5.7 ± 1.1 N·m (50.4 ± 9.7 lb in).


Illustration 15 g00810493

15.Put the O-ring seal on the shift lever housing. Put solenoid (1) in position on the shift housing. Make sure that the end of the plunger is inserted into the shift lever.


Illustration 16 g00810179

16.Install the three bolts and tighten the bolts to a torque of 14.1 N·m (124.8 lb in) to 21.5 N·m (190.3 lb in).

17.Connect motor terminal “MTR” (3) to the starter motor housing. Hold the terminal with a T40 TORX wrench. Tighten the nut on the solenoid motor terminal to a torque of 14.7 ± 3.4 N·m (130.1 ± 30.1 lb in). Tighten the motor terminal bolt to 9.6 ± 1.1 N·m (85.0 ± 9.7 lb in).

18.Connect the shunt wire assembly (4) to the solenoid (1) and to the starting motor. Tighten the nuts for the shunt wire assembly to a torque of 2.6 ± 0.8 N·m (23.0 ± 7.1 lb in).


Illustration 17 g00810580

19.Install the nut (6) for the plunger finger tight. The plunger must be adjusted for the correct pinion clearance.

20.Check pinion clearance. Refer to Testing and Adjusting, “Pinion Clearance Adjustment” for the proper adjustment procedure.
