Hub Caps/Wheel Covers
• The hub caps must be removed before raising the vehicle off the ground.
• For single rear-wheel (SRW) models, use the blade on the end of the lug wrenchto pry the hub cap off. Insert the blade end into the pry-off notch and carefully pop
off the hub cap with a back-and-forth motion.
• On models with dual rear wheels (DRW), you must first remove the hub caps. The jack handle driver has a hook at one end that will fit in the pry off notch of the rear
hub caps. Position the hook and pull out on the ratchet firmly. The hub cap should
pop off. The wheel skins can now be removed. For the front hub cap use the blade
on the end of the lug wrench to pry the caps off. The wheel skin can now be
removed.
• You must use the flat end of the lug wrench to pry off the wheel skins. Insert the flat tip completely and using a back-and-forth motion, loosen the wheel skin.
Repeat this procedure around the tire until the skin pops off.
• Replace the wheel skins first using a rubber mallet. When replacing the hub caps, tilt the cap retainer over the lug nut bolt circle and strike the high side down with
a rubber mallet. Be sure that the hub caps and wheel skins are firmly seated
around the wheel.
Wheel Nuts
• All wheel nuts should be tightened occasionally to eliminate the possibility of wheel studs being sheared or the bolt holes in the wheels becoming elongated.
This is especially important during the first few hundred miles/kilometers of
operation to allow the wheel nuts to become properly set. All wheel nuts should
first be firmly seated against the wheel. The wheel nuts should then be tightened
to recommended torque. Tighten the wheel nuts to final torque in increments.
Progress around the bolt circle, tightening the wheel nut opposite to the wheel nut
just previously tightened until final torque is achieved. Recommended torques are
shown in the following chart.
