20.Position the solenoid (7) over the plunger assembly. Install the bolts (9) and tighten the bolts to a torque of 12.2 ± 2.7 N·m (108 ± 24 lb in). Tighten the clamp.
21.Install the contact assembly (6). Install the insulator, the lockwashers, the washers, the nuts and the gasket onto the terminal assembly. Tighten the small nuts to a torque of 2.25 ± 0.25 N·m (20 ± 2.2 lb in). Tighten the larger nuts to a torque of 30 ± 3 N·m (22 ± 2 lb ft).
22.Connect the leads (5) to the back of the terminal assembly (2). Install the terminal assembly, the bolts and the nuts onto the solenoid. Tighten the nuts to a torque of 2.25 ± 0.25 N·m (20 ± 2.2 lb in). Connect the negative wire assembly to the ground terminal. Tighten the nut to a torque of 30 ± 3 N·m (22 ± 2 lb ft).Categories: 3126 | Tags: 3116, 3126, Delco 50-MT, starting motor | Leave a comment
