torque DODGE RAM 2001 Service Repair Manual

(4) Rotate the stud shaft between 180É and 270É to
the left of center and record the left off-center pre-
load. Repeat this to the right of center and record the
right off-center preload. The average of these two
recorded readings is the Preload Rotating Torque.
(5) The Over-Center Rotating Torque should be
0.23-0.68 N´m (2-6 in. lbs.)higherthan the Preload
Rotating Torque.
(6) If an adjustment to the Over-Center Rotating
Torque is necessary, first loosen the adjuster lock
nut. Then turn the pitman shaft adjuster screw back
(COUNTERCLOCKWISE) until fully extended, then
turn back in (CLOCKWISE) one full turn.
(7) Remeasure Over-Center Rotating Torque. If
necessary turn the adjuster screw and repeat mea-
surement until correct Over-Center Rotating Torque
is reached.
NOTE: To increase the Over-Center Rotating Torque
turn the screw CLOCKWISE.
(8) Prevent the adjuster screw from turning while
tightening adjuster lock nut. Tighten the adjuster
lock nut to 49 N´m (36 ft. lbs.).
