REMOVAL & INSTALLATION
See Figure 1
- Disconnect hoses at gear. When hoses are disconnected, secure ends in raised position to prevent drainage of oil. Cap or tape the ends of the hoses to prevent entrance of dirt.
- Install two plugs in gear fittings to prevent entrance of dirt.
- Remove the flexible coupling to steering shaft flange bolts.
- Mark the relationship of the pitman arm to the pitman shaft. Remove the pitman shaft nut or pitman arm pinch bolt and then remove the pitman arm from the pitman shaft using Puller J-6632.
- Remove the steering gear to frame bolts and remove the gear assembly.
- Remove the flexible coupling pinch bolt and remove the coupling from the steering gear stub shaft.
- Install the flexible coupling onto the steering gear stub shaft, aligning the flat in the coupling with the flat on the shaft. Push the coupling onto the shaft until the stub shaft bottoms on the coupling reinforcement. Install the pinch bolt and torque to specifications.
- Place the steering gear in position, guiding the coupling bolt into the steering shaft flange.
- Install the steering gear to frame bolts and torque to specifications.
- If flexible coupling alignment pin plastic spacers were used, make sure they are bottomed on the pins, tighten the flange bolt nuts to specifications and then remove the plastic spacers.
- If flexible coupling alignment pin plastic spacers were not used, center the pins in the slots in the steering shaft flange and then install and torque the flange bolt nuts to 80 ft. lbs. (110 Nm).
- Install the pitman arm onto the pitman shaft, lining up the marks made at removal. Install the pitman shaft nut or pitman arm pinch bolt and torque to 185 ft. lbs. (240 Nm).
- Remove the plugs and caps from the steering gear and hoses and connect the hoses to the gear. Tighten the hose fittings to 20 ft. lbs. (27 Nm).
