General
This section has the description and repair
procedures for the steering axle.
The steering axle assembly includes an axle frame,
steering cylinder, and two spindle and hub
assemblies. See Figure 1. The steering axle is
articulated and is connected to the frame with two
mounting plates and four capscrews and washers.
See Figure 2.
The end caps of the steering cylinder are also the
mounts for the cylinder and are held to the shell by
the mount capscrews. There are O-rings, seals, and
wipers in the end caps to seal the caps to the shell
and rod. 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 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.
When the piston reaches the end of the stroke, a
relief valve in the steering circuit controls the oil
pressure. The tie rods that connect the spindle
arms to the cylinder are not adjustable. See
Figure 1.
Each spindle turns on two tapered roller bearings
in mounts in the axle frame. The preload on the
bearings is controlled by shims at the lower bearing
cap.
