• When lifting parts or assemblies, make sure all slings, chains, or cables are correctly fas-
tened, and that the load being lifted is balanced. Make sure the crane, cables, and chains
have the capacity to support the weight of the load.
• Do not lift heavy parts by hand, use a lifting mechanism.
• Wear safety glasses.
• DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair on
electric lift trucks. Disconnect the battery ground cable on internal combustion lift trucks.
• Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT THE
LIFT TRUCK ON BLOCKS in the Operating Manual or the Periodic Maintenance section.
• Keep the unit clean and the working area clean and orderly.
• Use the correct tools for the job.
• Keep the tools clean and in good condition.
• Always use YALE APPROVED parts when making repairs. Replacement parts must meet
or exceed the specifications of the original equipment manufacturer.
• Make sure all nuts, bolts, snap rings, and other fastening devices are removed before using
force to remove parts.
• Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs, or
if the unit needs repairs.
• Be sure to follow the WARNING and CAUTION notes in the instructions.
• Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel are
flammable. Be sure to follow the necessary safety precautions when handling these fuels
and when working on these fuel systems.
• Batteries generate flammable gas when they are being charged. Keep fire and sparks away
from the area. Make sure the area is well ventilated.

Description
The steering axle assembly includes an axle weldment,
steering cylinder, and two spindle and hub assemblies.
See Figure 1. The steering axle assembly is connected
to the frame by rubber mounts. The rubber mounts per-
mit the steering axle to move in the lift truck frame when
the lift truck travels over rough surfaces.
The steering cylinder is held into the axle weldment us-
ing four bolts from the bottom of the axle weldment.
There are O-rings, seals, and wipers in the cylinder
guides to seal the guides to the shell and rod. The ends
of the piston rod extend from both ends of the cylinder.
A single piston and 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.
