ADJUSTMENTS



Adjustments to the manual steering gear are not necessary during normal service. Adjustments are performed only as part of overhaul.

Worm Bearing Preload
  1. Mount the gear in a vise.
  2.  
  3. Using an inch lbs. torque wrench and spanner KV48101400, or its equivalent, rotate the worm shaft a few turns in each direction to settle the bearing and measure the existing preload.
  4.  
  5. If preload is not 1.7-5.2 inch lbs. on 1989 models or 6.1-7.8 inch lbs. 1990-95 models loosen the locknut and turn the adjusting plug with the spanner, in a clockwise rotation ONLY. Never adjust preload by turning the adjusting plug counterclockwise. If preload cannot be obtained in this manner, rebuild the gear.
  6.  
  7. Apply liquid sealer on the shaft threads and tighten the locknut to 181-231 ft. lbs. (245-314 Nm) on 1989 models, or 166-188 ft. lbs. (226-255 Nm) on 1990-95 models.
