Steering Axle Assembly Repair
When the piston reaches the end of the stroke, a re-
lief valve in the steering circuit controls the oil pressure.
The tie rods that connect the spindle arms to the cylin-
der are not adjustable.
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.
The wheels rotate on two tapered roller bearings and
are held on the spindles by a castle nut. The bearing
preload of the wheels is adjusted by the castle nut. The
grease seals protect the bearings from dirt and water.
Wear sleeves protect the hub from wear by the seals.

WARNING
PUTTING THE LIFT TRUCK ON BLOCKS
The lift truck must be put on blocks for some
types of maintenance and repair.
The removal
of the mast, drive axle, battery, or counterweight
assemblies will cause large changes in the center
of gravity. When the lift truck is put on blocks, put
additional blocks in the following positions:
• If the mast and drive axle are removed, put blocks
under the counterweight so the lift truck cannot
fall backward.
• If the counterweight is removed, put blocks under
the mast so that the lift truck cannot fall forward.
Put the lift truck on blocks on a solid, even, and
level surface.
Verify the blocks or stands have
enough capacity to hold the lift truck.
Use ad-
ditional blocks next to the tires as necessary to
prevent movement of the lift truck. Verify the lifting
devices used during repairs can lift the weight of
the parts and assemblies.
See the Operating Manual or Periodic Maintenance
section for your lift truck model, for the procedures
to put the lift truck on blocks.
The steering axle can be removed without removing the
counterweight.
1.
Verify wheels are set for straight travel. Put lift truck
on blocks so the steering axle will have enough
clearance to be removed. The top of the axle frame
must have clearance under the bottom of the frame
at the rear of the lift truck.
2.
Disconnect hydraulic lines at steering cylinder. In-
stall plug fittings in cylinder and put caps on hy-
draulic lines. Plug fittings will prevent spindles from
turning as axle is removed from under the lift truck.
NOTE: Steering Axle Assembly may be mounted to the
frame with brackets or plates.
3.
Slide floor jack or forks of another lift truck under
steering axle. Raise lifting device until it holds the
weight of the axle assembly.
a.
To remove bracket type mounts, remove four
capscrews and nuts that fasten two brackets
under rubber mounts.
