INTRODUCTION
GENERAL
This section has the description and repair procedures
for the steering axle. For information on the steering
control unit, see the section THE STEERING CON-
TROL UNIT, 1600 SRM 54.
DESCRIPTION
The steering axle assembly includes an axle frame,
steering cylinder, tie rods and two spindle and hub as-
semblies. The steering axle is articulated and is con-
nected to the frame with center pivot mounts. The center
pivot mounts permit the steering axle to move in the
frame mount when the lift truck travels over rough sur-
faces.
The center pivots for the axle are installed in rubber
mounts on the following units:
H3.50–5.50XL (H70–110XL)
S/E3.50–5.50XL (S/E70–120XL).
The center pivots for the axle are installed in the frame
of the lift truck and rotate in fiber bearings on the follow-
ing units:
H6.00–7.00XL (H135– 155XL)
H8.00–16.00XL (H165–360XL).

The end caps of the steering cylinder are also the mounts
for the cylinder and are held to the axle by capscrews.
The ends of the piston rod extend from both ends of the
cylinder. A single piston and the seal are at the center of
the piston rod. Oil pressure on one side of the piston
moves the piston in the bore. The piston pushes an equal
amount of oil from the opposite side of the cylinder. The
oil returns to the steering control unit.
When the piston in the steering cylinder reaches the end
of the stroke, a relief valve controls the oil pressure. The
relief valve for the steering system is in the manifold
block that
