Wheel-Check® is a loose wheel nut indicator that can identify a loose wheel-nut with a simple visual inspection. When the wheel nuts are properly torqued to specs, the Wheel-Checks are then placed on the wheel nuts in a uniform pattern. (see diagram below)
The way the Wheel-Check® system works is once a wheel nut has loosened, the Wheel-Check® will become out of sequence. It will be visible when the driver does his walkaround check and it is the driver’s responsibility to call maintenance and have the wheel thoroughly serviced.
Wheel-Checks are also heat sensitive. If there is a binding brake or seized bearing, the heat is transferred through the stud and nut. If this temperature exceeds 120º C (248º F), the Wheel-Check® will start to blister around the circumference and eventually start to distort. The driver will be required to go to maintenance and have a thorough assessment on the problem wheel.
The use of Wheel-Check® in no way guarantees wheel-offs will not occur.
High temperature Wheel-Checks are available.
Custom sizes and colors are available upon request.
Wheel-Checks are reusable.
