are present, locate ball nut in center of
travel on worm shaft, then install pit-
man so it points straight forward.
Install steering gear assembly, then
turn adjusting screw (7) to adjust
clearance between sector gear and ball
nut so steering wheel free play is 20-30
mm (%-lV8 inches). Install seal washer

POWER STEERING SYSTEM
All Models So Equipped
20.
An integral hydraulic power assist
steering gear is available on some
models. On all models except 2110, a
priority valve is used to divert part of
the flow from the hydraulic lift system
pump to operate the power steering. On
2110 models, a separate hydraulic pump
supplies fluid to steering gear assembly.
The pump is located on left side of en-
gine and driven by the camshaft gear.
On all models, steering wheel free play
can be adjusted externally. Desired free
play is 20-30 mm (^-lVs inches) mea-
sured at outer rim of steering wheel. If
free play is excessive, adjust sector shaft
to ball nut clearance as follows: Start
engine and run at idle speed. Loosen
locknut (39-Fig. 32) and turn adjusting
screw (45) clockwise to reduce free play
to desired setting. Tighten locknut after
adjustment is completed.
