ADJUSTMENTS



Meshload

See Figure 1

  1. As required, raise and support the vehicle using jackstands.
  2.  
  3. Disconnect the pitman arm from the sector shaft using tool T64P-3590-F or equivalent.
  4.  
  5. Disconnect and cap the fluid return line at the reservoir return line pipe.
  6.  
  7. Place the end of the return line in a clean container and turn the steering wheel from stop to stop several times to discharge the fluid from the gear. Discard the used fluid.
  8.  
  9. Turn the steering gear 45° from the right stop.
  10.  
  11. Remove the steering wheel hub cover. Attach an inch lb. torque wrench to the steering wheel nut and determine the torque required to rotate the shaft slowly about 1 / 8 turn from the 45° position toward center.
  12.  
  13. Turn the steering wheel back to center and determine the torque required to rotate the shaft back and forth across the center position.
  14.  
  15. Specification for vehicles under 5000 miles is 12-24 inch lbs. If the vehicle has over 5000 miles, reset the meshload measured while rocking the input shaft over center is less than 10 inch lbs. greater than torque 45° from the right stop.
  16.  
  17. If reset is required loosen the adjuster locknut and turn the sector shaft adjuster screw until the reading is the specified value greater than the torque at 45° from the stop. Hold the sector shaft screw in place and tighten the locknut.

  1. Disconnect the pressure and return lines from the steering gear. Plug the lines and the ports in the gear to prevent entry of dirt.
  2.  
  3. Remove the upper and lower steering gear shaft U-joint shield from the flex coupling. Remove the bolts that secure the flex coupling to the steering gear and to the column steering shaft assembly.
  4.  
  5. Raise the vehicle and remove the pitman arm attaching nut and washer.
  6.  
  7. Remove the pitman arm from the sector shaft using tool T64P-3590-F. Remove the tool from the pitman arm. Do not damage the seals.
  8.  
  9. Support the steering gear, and remove the steering gear attaching bolts.
  10.  
  11. Work the steering gear free of the flex coupling. Remove the steering gear from the vehicle.
  12.  

To install:
  1. Install the lower U-joint shield onto the steering gear lugs. Slide the upper U-joint shield into place on the steering shaft assembly.
  2.  
  3. Slide the flex coupling into place on the steering shaft assembly. Turn the steering wheel so that the spokes are in the horizontal position. Center the steering gear input shaft.
  4.  
  5. Slide the steering gear input shaft into the flex coupling and into place on the frame side rail. Install the attaching bolts and tighten to 50-62 ft. lbs. (68-84 Nm). Tighten the flex coupling bolt 30-40 ft. lbs. (41-54 Nm).
  6.  
  7. Be sure the wheels are in the straight ahead position, then install the pitman arm on the sector shaft. Install the pitman arm attaching washer and nut. Tighten nut to 170-228 ft. lbs. (230-310 Nm).
  8.  
  9. Connect and tighten the pressure and the return lines to the steering gear.
  10.  
  11. Disconnect the coil wire. Fill the reservoir. Turn on the ignition and turn the steering wheel from left to right to distribute the fluid.
  12.  
  13. Recheck fluid level and add fluid, if necessary. Connect the coil wire, start the engine and turn the steering wheel from side to side. Inspect for fluid leaks.
