See Figures 1, 2 and 3
- Mount the gear on a holding fixture in a vise.
- Turn the stub shaft (the shaft that connects with the steering column) several turns in either direction.
- Mount an inch lb. torque wrench on the stub shaft and turn it lock-to-lock, counting the total number of turns. Divide that number by 2 and position the torque wrench and shaft at the mid-point.
- Measure the amount of force needed to turn the shaft past the midpoint in both directions. The force should be 3.5 inch lbs.
- To correct the adjustment, loosen the locknut on the adjusting screw and turn the screw to give the correct torque. Tighten the locknut to 21-25 ft. lbs. (28-34 Nm) on all except 1986-88 models (D21D series) where it should be 25-29 ft. lbs. (34-39 Nm).
REMOVAL & INSTALLATION
See Figure 4
- Matchmark and remove the pitman arm from the sector shaft, using a puller such as special tool 290200001.
- Matchmark and disconnect the steering stub shaft from the gear at the coupling.
- Disconnect the fluid lines from the gear and cap the lines and openings in the gear.
- Unbolt and remove the gear assembly from the frame.
Installation is the reverse of the removal procedure. When installing, observe the following torques:
Gear housing-to-frame: 62-71 ft. lbs. (84-96 Nm).
