Installation

1. Inspect mounting bore sleeves (9, Figure 3-3)
and bearing spacers for damage or wear.
Check fit of pins in bores prior to installing sus-
pension.
2. Secure suspension to fork lift and raise into posi-
tion. (Suspension assembly should be retracted
as far as possible prior to installation.)
3. Position top suspension eye with its spherical
bearing, between the ears on the frame as
shown in Figure 3-3. Be certain the upper and
lower mounting eyes are aligned and the vent
plugs are positioned to the rear.
4. Lubricate the pin (1), align the retaining cap-
screw hole with the hole in the mounting bore
and drive in far enough to hold pin in position.
5. Insert the spacer (4) and continue to drive the
pin in through the spherical bearing. Insert the
remaining spacer and continue to drive the pin
in until the retaining capscrew hole is aligned
with the hole in the pin.
6. Install capscrew (2, Figure 3-3) and locknut (3).
Tighten to 310 ft. lbs. (420 N.m) torque.
7. Lower the suspension housing until the lower
mount bearing aligns with the bore in the rear
axle housing and repeat the above procedure to
install the bottom pin. The parts in the top and
bottom joint are identical.
8. Install the nitrogen charging kit and add nitrogen
to raise frame off stands or cribbing, or use a
lifting device if available.
9. Connect lubrication lines. Connect pressure
sensor.
10. Service the suspension. For instructions, refer to
®
HYDRAIR II "Oiling and Charging Procedure",
