Wheels & Lug Nuts
Wheel Installation
CAUTION
Retorque wheel studs after 10 hours of operation.
Make sure brakes are not engaged.
Check all parts are free of dirt and grease. Make sure all parts are free of damage. The hub or drum
mounting face must be cleaned and kept
fl

Ensure that the brake drum is on the pilots’ raised step, seated fully against the hub.
Clean the wheel’s center hole as necessary so it will

loosen prematurely.
Position hub with one pilot at 12 o’clock position. Place wheel onto hub carefully so as not to damage stud
threads. Make sure wheel is fully seated against drum.
