CENTER THE STEERING GEAR

Rotate the input shaft clockwise until it stops.

While counting the rotations, rotate the input shaft counter clockwise until it stops.

Rotate the input shaft clockwise 1/2 the rotations counted in the previous step.

Mark the input and pitman shaft in relation to the housing.

PITMAN SHAFT ALIGNMENT

1. Center the steering gear. Refer to

Center the Steeing Gear

for information regarding centering

the steering gear.

2. Install the pitman arm parallel with the input shaft orientated as shown in the illustration.

3. Torque the pitman arm nut to 75-100 ft-lbs
