CAUTION
To prevent the steering damper from interfering
with the adjustment of turning angles, make
sure its fixing bracket is at correct location on
the axle (refer to "12.2 Steering Stabilizer
Cylinder (Damper)).
Hydraulic Stop
CAUTION
Reduce or shut off the power steering hydraulic
pressure before the boss on the axle touches
the stop screw. If not, the components of the
front axle will be damaged (refer to
"ZF-
SERVOCOM Repair Manual"
and “ZF-
SERVOCOM Operating, Servicing
/Maintenance and Inspection Instructions”,
under heading
"Setting The Steering Limiter").
CAUTION
Never maintain the relief pressure for more
than 5 seconds, since damage to the power
steering pump may occur.
9. STEERING LINKAGE ADJUSTMENT
The steering linkage includes the pitman arm,
drag link, steering arm, tie rod arms and tie rod.
Perform lubrication according to “DANA SPICER
Service Manual NDS Axle Range” found in the
OEM manuals folder.
Steering linkage pivot points should be checked
each time they are lubricated. Looseness can be
visually detected while rotating the steering wheel
in both directions. Replace defective parts.
CAUTION
Front wheel alignment should be checked and
adjusted if necessary, any time a component of
the steering system is repaired, disassembled
or adjusted. Refer to section 10
"Front Axle"
under heading
6. "Front Wheel Alignment".
10. PITMAN ARM
10.1 REMOVAL
1. Remove cotter pin, nut and washers from
drag link ball stud at pitman arm.
2. Disconnect drag link from pitman arm, using
jaw style pullers (pressure screw type).
WARNING
Always wear approved eye protection when
operating pullers.
CAUTION
Do not drive (hammer in) pitman arm on or off
pitman shaft as this can damage the steering
gear.
CAUTION
Heating of components to aid in disassembly is
not allowed because it has a detrimental effect
on axle components and steering linkages.
