axles. Position drag links (Detail 5) into relay arms
(Details 8 and 9), (Figure 8-8) thread nut onto drag links
and torque 135-170 Nm (99.5-125 ft-lb) and install cotter
pin thru nut.
Keep clamps on drag links rotated away from frame to
assure no interference. Adjust drag links (Detail 5),
(Figure 8-8) to fit between the relay arms (Details 8 and
9), (Figure 8-8) and the axle steer arms.
5. Check the position of the pitman arm on the steering
gearbox and adjust if necessary; the timing marks
(arrows) on the gearbox shaft and the letter ‘B’ on the
pitman arm should align, if not make adjustment per
Steering System
, page 8-12. Torque pitman nut to 613
Nm (450 ft-lb) after making adjustment.
6. Attach drag link (Detail 6), (Figure 8-8) to the pitman and
secure with cotter pin. Adjust drag link length as needed
to fit between the pitman arm and the front relay arm
(Detail 9), (Figure 8-8) while keeping the pitman arm
position fixed. Be sure the drag link clamp is turned in
toward the carrier frame with bolt facing down. Secure
drag link to front relay arm (Detail 9), (Figure 8-8) with
cotter pin.
7. Remove the relay arm rig pins and secure all drag links.
8. Check that the rod ends on all drag links are within the
limits shown in the figure.
Air Ride Adjustment
NOTE: This model is equipped with an air ride front and
rear suspension. It is necessary to periodically
inspect the suspension for proper adjustment.
Operating this machine with incorrect ride height
adjustments could result in poor ride quality or
p o s s i b l e d a m a g e t o s u s p e n s i o n a n d a x l e
components.
1. Front Axle Ride Height - 11.75 In (Figure 8-5).
2. Rear Axle Ride Height - 15.25 In (Figure 8-6).
3. Adjust rod to achieve proper ride height setting
(Figure 8-7) and torque P-clamp on P-boot to 10 - 15
in lbs.
NOTE: Over-tightening of the P-clamp will cut through the
P-boot.
Final Adjustments
1. Inflate tires to the pressure specified on the tire inflation
chart located on the carrier cab door.
2. Start the engine and allow both air systems to reach full
system pressure. Make sure that the crane is on a flat
level surface. Make sure the top surface of each saddle
assembly is parallel with the bottom surface of the
carrier frame by measuring the distance at the front and
rear of the saddle assemblies. If necessary, adjust the
height control valves to raise or lower the saddle
assemblies into a parallel position.
3. To ensure proper adjustment, drive the front wheels onto
greased plates or a suitable turntable so that the friction
between the tires and ground is reduced.
4. If greased plates are not available, raise the crane 3.75
cm (1.5 in) from the static height by lowering the
outrigger jack cylinders. This will allow adjustment of the
drag links without damage, but will require rechecking
the alignment after the axles are fully loaded.
