Remove pitman arm nut and mark relative position of arm to shaft. Remove arm using suitable tool. Remove horn shroud and spring. 2) Turn steering wheel in one direction until stopped by gear, then turn back half way. CAUTION – Do not turn wheel hard against stops, as damage to ball guides may result. Measure and record ”bearing drag” by applying torque wrench to steering wheel nut and rotate through 90° arc. NOTE – Do not use torque wrench having a maximum reading of more than 50 INCH lbs. 3) Adjust “over—center preload” by turning steering wheel from one stop to the other. Turn wheel back exactly half way, to obtain center position. Turn lash adjuster screw clockwise to eliminate backlash between ball-nut and pitman shaft sector gear. Tighten lock nut. 4) Check torque at steering wheel, taking highest reading as wheel turns through center. To adjust to specifications, loosen lock nut and readjust lash screw to obtain proper torque. Tighten lock nut to specifications and recheck torque on steer-ing wheel. S) if maximum specification is exceeded, turn adjusting screw counterclockwise, then turn adjuster lock nut clockwise. Reassemble pitman arm to shaft, lining up marks made during removal. Tighten pitman shaft nut to specifications.
