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)

12.00XM-12EC (H360HD-EC) (E019, F019, G019)
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 pres-
sure. The relief valve for the steering system is in
the manifold block that is installed on the steering
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 tie
rods that connect the spindle arms to the cylinder do
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 bearings
from dirt and water. Wear sleeves prevent the seals
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 sure
the 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.
3. Slide a floor jack or forks of another lift truck
under steering axle. Raise lifting device until it
holds the weight of the axle assembly. Remove
four capscrews and nuts that fasten two brack-
ets under rubber mounts. Remove brackets and
slowly lower axle assembly. Carefully remove
axle assembly from under lift truck.
Install
1. Install rubber mounts on axle. Make sure part
number is away from axle frame and tapered
edge of rubber mount is at the top. See Figure 1
and Figure 3.
2. Apply a lubricant that is approved for use with
rubber (tire lubricant) to the rubber mounts.
Lubricant is used where rubber mount fits into
frame brackets.
3. Use a floor jack or another lift truck to put steer-
ing axle into position in the frame. Make sure
rubber mounts fit inside frame brackets for the
mounts. If necessary, lower weight of the lift
truck onto axle to make sure rubber mounts fit
completely in frame brackets.
4. Install bottom brackets for rubber mounts.
H3.50-5.00XL (H70-110XL) (G005) units.
Tighten four bolts for brackets to 88 N•m
(65 lbf ft).
S3.50-5.50XL (S70-120XL) (D004), S3.50-

(D098/E098) units. Tighten four bolts to
110 N•m (81 lbf ft).
5. Remove plugs and caps and connect hydraulic
lines to steering cylinder. Install wheels if they
were removed.
6. Operate steering system to remove air from sys-
tem. Turn steering wheel several times from one
wheel stop to other wheel stop. Check for hy-
draulic leaks.

WARNING
Excessive play in the pivot bushings will result
in increased shock loadings to the pivot pins
and increased movement of the axle, and may
affect steering responsiveness. If movement in

REMOVE AND DISASSEMBLE
WARNING
Completely remove the air from the tire before
removing the tire and wheel from lift truck.
Air pressure in the tires can cause the tire and
wheel parts to explode, causing serious injury
or death.
1. Raise axle to remove weight from tires, but have
tires still touching the floor. Loosen wheel nuts
just enough so they can be easily removed. Raise
axle so tires can be removed. Use a tire jack to
remove tires and wheels.
2. If a tire jack is not available, raise axle only
enough so tires are just touching the floor. Slide
tires from axle while they are still on the floor.
3. Remove hub cap, cotter pin and washer.

CLEAN
WARNING
Cleaning solvents can be flammable and toxic
and can cause skin irritation. When using
cleaning solvents, always follow the recom-
mendations of the manufacturer.
Clean all parts with solvent. Make sure bearings are
clean and dry.
INSPECT
Inspect spindle to ensure it does not have any rough
or sharp areas that would prevent the bearings from
being correctly installed. If necessary, smooth any
rough or sharp areas before installing the bearings.
ASSEMBLE AND INSTALL
1. If bearings in hubs must be replaced, use a press
to install new bearing cups in hub. Install a new
wear sleeve in wheel hub.
CAUTION
Do not damage the seals during installation.
2. Install grease seal on spindle. Lubricate bearing
cones and seal surfaces with grease. Make sure
bearings are filled with grease. Install bearing
cone on spindle.
3. Carefully slide hub onto spindle. On some units,
the hub weighs enough to require a lifting device
during installation. Install outer bearing cone.
