• Reverse the assembly in the vise so that the worm
end is down. Use an inch pound torque wrench on
the input shaft, note the torque required to rotate
the input shaft 360 degrees in each direction (fig
ure 9). Tighten the bearing adjuster to increase the
maximum torque at the input shaft 0.56 to 1.13
N-m (5 to 10 in. lbs.).
• Rotate the assembly in the vise.

Tighten
• Jam nut to 154 N-m (112 ft. lbs.) using J 37070
and J 37464 (figure 10).
• Recheck the input shaft torque and repeat above
procedure as necessary. Stake the valve housing
into the clockwise most corner of the two opposing
slots in the jam nut. Stake the jam nut into the
adjuster in one place at threaded area using a suit-,
able punch. Choose areas that have not been pre
viously staked.

• Torque required to rotate the input shaft must be
between 0.56 to 1/T3 N m (5 to 10 in. lbs.) rnore
that the original torque that was noted.
•T h e torque.required to rotate the input shaft must
not be more than 2.5 N-m (22 in. lbs.). Unstake
. and adjust as necessary.
