With the steering gear mounted in a vise, and the Pitman are positioned
in a ``wheels straight ahead'' position, attach a spring scale and adapter
49 0180 510B to the wormshaft.
Check the rotating torque of the wormshaft. Rotating torque should be 2.2
lbs. or less and at least 1⁄2 to
1 lb. higher than what the rotating torque is at a point 360°from straight
ahead.
If preload is not correct, hold the adjusting screw on top of the gear with
a screwdriver and loosen the locknut. Turn the adjusting screw to obtain the
correct preload.
When preload is correct, hold the adjusting screw and tighten the locknut
to 35 ft. lbs. Make sure that the adjusting screw does not move while the
locknut is being tightened.
