Dump Trailers - Owner's Manual

Maintenance And Service


Collision hazard.

Worn, damaged or under-inflated tires can cause loss of control, injury and damage.

Check tires before towing trailer.

9.3 WHEELS Whenever tires/wheels are removed, check the condition of the wheel, wheel lugs, hubs and studs. Replace any damaged, corroded or worn parts. Use the correct wheel lugs and wedges (if equipped) for your trailer.


Wheel Failure Hazard.

• Never weld on wheel or hub for any reason • Never install aluminum wheels on an axle designed for steel wheels. The stud length is greater for aluminum wheels than steel wheels. • Always use the correct lugs and wedges (if equipped).

9.3.1 SPOKE WHEELS Lug nuts are prone to loosen right after a wheel is mounted to a hub. When driving on a remounted wheel, check to see if the lug nuts are tight after the first 50-100 miles of driving and weekly thereafter.

When removing a wheel from a trailer equipped with spoke wheels, care must be taken to avoid injury.


Flying Projectile Hazard.

Wedges can fly out with force when removing wheel.

Partially loosen wheel lugs and relieve tension on wedges before removing wheel lugs.

Loosen the wheel lugs but do not remove at this time. With the wheel lugs loose, strike the wedges with a hammer to free tension on wedges. Now the wheel lugs and wedges can be removed.

Install wheel, wedges and lugs. Rotate the wheel and set runout to a maximum of 1/8 inch. Evenly tighten lugs to 200-250 lb/ft of torque.


Wheel Failure Hazard.

Lug nuts are prone to loosen after being first assembled. Death or serious injury can result.

Check lug nuts for tightness on a new trailer, and after re-mounting a wheel after the first 50-100 miles and weekly thereafter.
