steering arm.
For additional details please refer to ZF

and
Lemförder

11.1 FINE
ADJUSTMENT
The drag link fore end is provided with an
adjusting sleeve which has internal and external
left and right threads. Turning this sleeve allows
fine adjustments to the length of the drag link.
Apply a small amount anti-seize compound on
the threads for corrosion protection. Be sure to
avoid smearing the ball joint boot.

12. STEERING SYSTEM MAINTENANCE
The power steering system requires little
maintenance. However, the system should be
kept clean to ensure maximum operating
performance and trouble-free service. Periodic
inspections should also be made to check for
leakage and all parts for damage or distortion.
Insure all fasteners are tight (see
"14.
Specifications"
for recommended tightening
torques.
When the slightest evidence of dirt, sludge or
water is discovered in the system, disconnect fluid
lines at the power steering gear to drain the
system. Drain and refill the system.
Air in the hydraulic system will cause spongy
action and noisy operation. When a hose has
been disconnected or when fluid has been lost for
any reason, the system must be bled. Bleed
system as outlined under heading 3
: "Bleeding
Power Steering Hydraulic System".
CAUTION
Do not operate the pump without fluid in the
power steering fluid reservoir.
If the steering linkage between the steering gear
and the two front wheels is not properly adjusted,
or if it is bent, twisted or worn, the steering of the
vehicle will be seriously impaired. Whenever a
steering linkage part is repaired, replaced or
adjusted, steering geometry and front wheel
alignment must be checked and necessary
corrections made. Refer to section 10
"Front
Axle"
under heading 6:
"Front Wheel Alignment"
.
