Pitman Shaft Overcenter Drag Torque - Jeep 1979 CJ-5 Technical & Service Manual

Pitman Shaft Overcenter Drag Torque
(1) Turn pitman shaft adjuster screw counter-
clockwise until screw is fully extended, then turn screw
back 1/2 turn clockwise.
(2) Rotate stub shaft from stop-to-stop and count
total number of turns.
(3) Starting from either stop, turn stub shaft back
1/2 total number of turns. This is gear center.
NOTE: When the gear is centered, the flat on the stub
shaft should face upward and be parallel with the side
cover (fig. 2L-44). In addition, the master spline on the
pitman shaft should be in line with the adjuster screw
(fig. 2L-J>5).

(4) Install 50 inch-pound (6 N*m) torque wrench
and deep socket on stub shaft and place wrench in verti-
cal position to take reading (fig. 2L-46).
(5) Rotate torque wrench 45 degrees each side of
center and record highest drag torque measured on or
near center (fig. 2L-46). Record drag torque reading.
(6) Adjust drag torque by turning pitman shaft ad-
juster screw clockwise until desired drag torque is ob-
tained. Adjust drag torque to following limits:
On new gears, add 4 to 8 inch-pounds (0.45 to 0.90 N»m)
torque to previously measured wormshaft bearing pre-
load but do not exceed a combined total of 14 inch-
pounds (2 N®m) drag torque.
On used gears (400 or more miles)
f
add 4 to 5 inch-
pounds (0.5 to 0.6 N*m) torque to previously measured
wormshaft bearing preload but do not exceed a com-
bined total of 14 inch-pounds (2 N*m) drag torque.
(7) Tighten pitman shaft adjuster screw locknut af-
ter adjusting overcenter drag torque. Tighten locknut to
35 foot-pounds (47 N*m) torque. Use hex wrench to
prevent adjuster from turning while tightening adjuster
