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 suspension.
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 capscrew
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 re-
maining 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 343 ft. lbs. (465 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 sen-
sor.
10. Service the suspension. For instructions, refer to
HYDRAIR

11. Install piston rod shield (2, Figure 3-1) with the
capscrews, flat washers, and lockwashers.
