FIGURE 13: CLOCKSPRING INSTALLATION
4. Mount the clockspring in place with 2
screws.
5. Break the paper seal and rotate the center
part of the clockspring about 50° clockwise
(Fig. 14). This step is necessary for the
installation of the steering wheel.

6. Reinstall the steering wheel.
9. TURNING ANGLE ADJUSTMENT
The maximum turning angle is set through two (2)
steering stop screws installed on the axle center.
Steering stop screws are factory adjusted to
accommodate the chassis design, and therefore,
do not require adjustment on new vehicles.
However, these should be checked and adjusted
if necessary, any time a steering system
component is repaired, disassembled or adjusted.
Refer to section 10
"Front Axle" under heading
‘’6.4 ‘’Turning Angle Adjusment".
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”
annexed to this section, 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.
10. 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
NDS Axles Lubrication and Maintenance"
annexed to section 10 "Front Axle".
Drag link ends are provided with grease fittings.
Under normal conditions, these should be
serviced every 6,250 miles (10 000 km). Refer to
section 24
"Lubrication".
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".
