Torque Procedures
1. Start all bolts or nuts by hand to prevent cross threading.
2. Tighten bolts or nuts in the sequence shown below for Wheel Torque
Requirements. (See Figure 1.)
3. The tightening of the fasteners should be done in stages. Following the
recommended sequence, tighten fasteners per Wheel Torque Requirements
shown below.
4. Wheel nuts/bolts should be torqued before first road use and after each
wheel removal.
IMPORTANT!
Check and re-torque after the
fi
rst 10 miles, 25 miles and
again at 50 miles. Check periodically thereafter.
Torque Requirement DO’s:
• DO remove all oil and grease from threaded fasteners (studs and lugs).
• DO mask or shield (cover) all fastener contact surfaces (mounting surfaces
and studs) before painting axles, whether for improved cosmetics or for
corrosion protection.
Wheel Mounting and Application for Utility and Enclosed Trailers
Guidelines
1. Surfaces of contact on an aluminum wheel (the nut seat and the
mounting surface) must be free of paint, contamination and damage.
Smooth, clean surfaces provide the most uniform clamping pressure
and best retain torque.
2. Surfaces of contact on a steel wheel (the nut seat and the mount-
ing surface) must be free of excessive paint, contamination and
damage. Smooth, clean surfaces provide the most uniform clamping
pressure and best retain torque.
3. Surfaces ot contact on the axle (the flat hub surface and the
threaded studs) must be free of excessive paint, oils, grease,
contamination and physical damage.
4. Lug nut geometry must match that of the wheel nut seat. The
threads and nut seat must be free of paint, oils, grease, and other
contamination.
5. Stud length must be sufficient that after mounting the wheel to the
hub, the lug nut is engaged to a depth at least equivalent to the
diameter of the stud. For example, a lug nut threaded on a 1/2 inch
diameter stud should thread on for a depth of at least 1/2 inch.
