Wheel and Tire Replacement 8000 SRM 707
Remove and Install Tire on Wheel
1. The correct tools, equipment, and a press ring
must be used for each size of wheel. Use a press
to push wheel from rim and tire. The capacity of
the press must be approximately 355 to 1770 kN
(80,000 to 400,000 lbf). For the tire sizes, see the
nameplate.
WARNING
Check all wheel nuts after 2 to 5 hours of opera-
tion: when new lift trucks begin operation and
on all lift trucks when the wheels have been
removed and installed. Tighten the nuts in a
cross pattern to the correct torque value shown
in the Maintenance Schedule. When the nuts
stay tight for 8 hours, the interval for checking
the torque can be extended to 250 hours.
NOTE: Make sure tires are installed on wheels so
outside edges of tire and wheel are as shown in Fig-
ure 45. Also check nameplate of lift truck for the cor-
rect tire size and tread width.
2. When the drive wheels are installed on the lift
truck, tighten wheel nuts to the value shown in
the Maintenance Schedule.
3. The steering wheels are fastened to the spindle of
the steering axle with a large castle nut. Make
sure inner and outer bearings are correctly lu-
bricated with grease. Install inner bearing as-
sembly and wheel on spindle. Install outer bear-
ing cone and castle nut. Tighten castle nut up
to 200 N•m (150 lbf ft) while the wheel is ro-
tated. Loosen castle nut until hub turns freely
with no looseness. The torque must be less than
27 N•m (20 lbf ft). Tighten castle nut to 34 N•m
(25 lbf ft). Install cotter pin in castle nut at the
first alignment. Install cap for bearings.
NOTE: OUTSIDE EDGES OF WHEEL AND TIRE RIM ARE EVEN FOR ALL DRIVE AND STEER WHEEL ASSEM-
BLIES.
