STUD-PILOTED MOUNTING
Wheels with the stud-piloted mounting system are called stud mount wheels. Stud mount wheels are
designed to be centered by the nuts on the studs. The seating action of the chamfered nuts in the
chamfered bolt holes centers the wheels (see Figures 10 and 11).

For dual rear wheels, slide the inner dual wheel over studs, being careful not to damage the stud
threads. Snug up the inner cap nuts to 50 ft-lbs in sequence shown in Figure 9. Do not tighten them
fully until all have been seated. This procedure will permit the uniform seating of nuts and ensure the
even, fact-to-face contact of wheels, hub and drum. Tighten to 450-500 ft.-Ibs (dry) using the same
criss-cross pattern.
Align the hand holes to allow access to the air valves.
Nuts must be kept tight by retorquing nuts on a
routine basis and using the proper nut torque and tightening sequence.
Loose nuts could result in loose wheels or premature wheel failure. This can
result in an accident or injury.
