Frequently Asked Questions

Yes. Wheel Mounting CompoundWM-10™ is used as an alternative to traditional linseed-oil and lead-containing wheel mounting compounds. WM-10 is actually a safer option:  It poses no hazards of lead exposure, and linseed oil-soaked materials can spontaneously combust.

Wheel Mounting Compound WM-10™ is applied evenly to the axle wheel seat and the inside surface of the wheel bore after the mating surfaces are properly prepared. 

WM-10 may be applied by brush or roller to provide visible, consistent coverage. Always follow applicable AAR requirements and your facility’s approved wheel-mounting procedures.

Chatter can occur when friction between the wheel bore and axle wheel seat prevents them from moving smoothly during the press-fit operation. Wheel Mounting Compound WM-10™ helps reduce inconsistent friction at the interface, allowing the wheel to advance more evenly under pressure.

Smoother movement can help reduce vibration, noise, and sudden changes in resistance that may affect the mounting curve or contribute to alignment difficulties. NOTE:  WM-10 does not correct dimensional, surface-preparation, or equipment problems.

Yes. Wheel Mounting Compound WM-10™ was approved in 1997 and is listed as an approved wheel-mounting compound in the AAR Manual of Standards and Recommended Practices, Section G, Part II—Wheel and Axle Shop Manual.
