Infill Preload
Adjustment
(1) Tighten worm bearing adjuster until it bottoms,
then back off adjuster 1/4 turn.
(2) Install socket and Torque Wrench J-7754 on
splined end of wormshaft.
(3) Rotate wormshaft clockwise to stop; then back
off shaft 1/2 turn.
(4) Tighten worm bearing adjuster until torque re-
quired to rotate wormshaft is 5 to 8 inch-pounds (0.60 to
0.90 N*m).
CAUTION: The preload adjustment must be made
with the wormshaft turned back no more than 1/2 turn
from either the right or left turn stop positions.
(5) Tighten worm bearing adjuster locknut to 90
foot-pounds (122 N # m ) torque. Recheck wormshaft ro-
tating torque and readjust if necessary.
(6) Record worm bearing preload torque reading.
?\\mm %M\ Overcenter Dray Torque Adjustment
(1) Rotate wormshaft from stop-to-stop and count
total number of turns.
(2) Turn wormshaft back 1/2 total number of turns
to place ball nut and pitman shaft in centered position..
(3) Install socket and Torque Wrench J-7754 on pit-
man shaft splines (fig. 2K-18).
(4) Tighten pitman shaft adjuster screw (while ro-
tating shaft back and forth over center) until torque
required to rotate shaft over center equals worm bear-
ing preload setting.
(5) Rotate shaft over center and continue tightening
adjuster screw until drag torque is increased by addi-
tional 4 to 10 inch-pounds (0.45 to 1.13 N®m) but do not
exceed total of 16 inch-pounds (1.81 N*m).
CAUTION: The total amount of over center drag
torque (worm bearing preload setting plus additional 4-

10 inch-pounds) must not exceed combined total of 16
inch-pounds (1.81
N 9 m).
(6) Hold adjuster screw in position using screw-
driver and tighten adjuster screw locknut to 23 foot-
pounds (31 N*m) torque. Do not allow screw to turn
when tightening locknut.
N O T E : If the adjuster screw is allowed to turn when
the locknut is tightened, the entire drag torque adjust-
ment procedure will have to be performed once again.
(7) Recheck overcenter drag torque and readjust if
necessary.
