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 as-
semblies 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 addi-
tional blocks next to the tires as necessary to pre-
vent 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 Mainte-
nance manual listed in the General section of this
manual for the procedures to put the lift truck on
blocks.
NOTE:
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 bot-
tom of the frame at the rear of the lift truck.
2.
Disconnect hydraulic lines at steering cylinder.
Install plug fittings in cylinder and put caps on
hydraulic lines. Plug fittings will prevent spin-
dles from turning as axle is removed from un-
der the lift truck. See Figure 3.
3.
Slide floor jack or forks of another lift truck un-
der steering axle. Raise lifting device until it
holds the weight of the axle assembly.
4.
Remove four capscrews and washers from two
mounting plates on bottom of steering axle and
lift truck frame. See Figure 3.
5.
Remove mounting plates and slowly lower
steering axle assembly onto wheels. Carefully
roll steering axle assembly away from lift truck.
DISASSEMBLE
NOTE:
If the spindle, bearings or tie rods need to
be repaired, go to Spindles, Bearings, and Tie Rods
Repair section for repair procedures.
1.
Remove ring seal, shims, flange, stub shaft and
bushing from steering axle assembly. See Fig-
ure 4.
2.
Put axle on blocks so the wheels just touch the
floor. Remove hub cap. Remove cotter pin,
washer, and castle nut. Remove bearing cone
and discard cotter pin.
NOTE:
Identify and tag the outer and inner bear-
ing cones so they can be reassembled in their origi-
nal locations.
3.
Slide wheel from spindle. Remove inner bearing
cone, wear ring, and oil seal from spindle. See
Figure 3.
NOTE:
If the bearing is replaced, then the associ-
ated bearing cup must be replaced also.
4.
If the bearings must be replaced, use a brass
drift pin to remove the bearing cups and wear
ring.
5.
Repeat Step 1 through Step 4 for other wheel.
