General
This section has the description and repair procedures for the steering axle. For information on the steering
control unit, see the section Steering Control Unit.
DescriptionThe steering axle assembly includes an axle frame,
steering cylinder, tie rods, and two spindle and hub
assemblies. The steering axle is articulated and is
connected 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 surfaces. See Figure 1, Figure 2,
Figure 3, and Figure 4.
The center pivots for the axle are installed in rubber
mounts on the following units:
H3.50-5.50XL (H70-110XL) (D004)
S3.50-5.50XL (S70-120XL) (G005)
S3.50-5.50XM (S70-120XM) (E004, F004)
E3.50-5.50XL (E70-120XL, E70-120XL3) (C098)
E3.50-5.50XL, E4.50XLS (E70-120Z, E100ZS)
(D098)
The center pivots for the axle are installed in the
frame of the lift truck and rotate in fiber bushings
on the following units:
H6.00-7.00XL (H135-155XL, H135-155XL2) (F006,
G006)
H8.00-16.00XL (H165-360XL) (D019, E007)H8.00-16.00XM (H170-360HD) (E019, F007, F019,
G007)
The end caps of the steering cylinder are also th
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 th
seal are at the center of the piston rod. Oil pressur
on one side of the piston moves the piston in the bore
The piston pushes an equal amount of oil from th
opposite side of the cylinder. The oil returns to th
steering control unit.
When the piston in the steering cylinder reaches th
end of the stroke, a relief valve controls the oil pressure. The relief valve for the steering system is in
the manifold block that is installed on the steerin
control unit.
Each spindle turns on two tapered roller bearings in
the axle frame. The preload on the bearings is con
trolled by shims at the lower bearing cap. The ti
rods that connect the spindle arms to the cylinder d
not have an adjustment.
The wheel hubs rotate on two tapered roller bear
ings and are held on the spindles by a castle nut
The bearing preload of the wheel hubs is adjusted by
the castle nut. The grease seals protect the bearing
from dirt and water. Wear sleeves prevent the seal
from causing wear on the hub.

WARNING
Put the lift truck on blocks. Follow the proce-
dures for raising the lift truck described in the
Operating Manual for this lift truck. The sur-
face must be solid, even, and level. Make sure
the blocks are solid, one-piece units. Make surethe lifting devices used during repairs can lift
the weight of the parts.
The steering axle can be removed without removing
the counterweight.
1. Make sure wheels are set for straight travel. Put
blocks under frame in front of steer wheels and
under counterweight so steering axle can be re-
moved. The top of the axle frame must have
clearance under the counterweight so that the
steering axle can be removed.
2. It is not required, but it can make removal of the
axle easier if wheels are removed. See Wheels
and Hubs Repair (All Units) for wheel removal.
Disconnect hydraulic lines at steering cylinder.
Install caps on cylinder and put plugs in hy-
draulic lines. Caps will prevent spindles from
turning when axle is removed from the lift truck.
