SERVICE OPERATIONS
METRIC LUG NUTS AND WHEEL STUDS
All models use metric lug nuts and wheel studs (size: M12
y
1.25).
WHEEL REMOVAL
1) Loosen wheel nuts by approximately 180
5
(half a rotation).
2) Hoist vehicle.
3) Remove wheel.
CAUTION:
Never use heat to loosen tight wheel because applica-
tion of heat to wheel can shorten life of wheel and
damage wheel bearings.
Wheel nuts must be tightened in sequence and to proper torque to
avoid bending wheel or brake drum or disc.
NOTE:
Before installing wheels, remove any build-up of corrosion on
wheel mounting surface and brake drum or disc mounting
surface by scraping and wire brushing. Installing wheels with-
out good metal-to-metal contact at mounting surfaces can
cause wheel nuts to loosen, which can later allow a wheel to
come off while vehicle is moving.
Tightening Torque
(a): 55 N·m (5.5 kg-m, 40.0 lb-ft)
TIRE MOUNTING AND DEMOUNTING
Use a tire changing machine to mount or demount tires. Follow
equipment manufacturer’s instructions. Do not use hand tools or
tire irons alone to change tires as they may damage tire beads or
wheel rim.
Rim bead seats should be cleaned with a wire brush or coarse steel
wool to remove lubricants, old rubber and light rust. Before mount-
ing or demounting a tire, bead area should be well lubricated with
approved tire lubricant.
