Truck wheel balancer backing spacer, listed 40 mm shaft, silver

Truck wheel balancer backing spacer

This silver-colored, cup-shaped spacer is listed for a 40 mm shaft application on Coats wheel balancers. It has a recessed face, a raised circular rim and a central through-hole. The reverse face is flat. The photos show one spacer; a mounting cone, shaft nut and balancer are not included in the pictured set.

Check the center opening before ordering

The shaft application is listed as 40 mm, while the dimension photo labels the center opening as 1.56 inches. Those values are not an exact conversion. Confirm the actual bore and required clearance against your machine's shaft before ordering.

The same photo marks a 6.86-inch span across the recessed opening and a 2.50-inch height. The span does not establish the outside diameter, and the height is not a wall-thickness measurement. Compare the complete spacer profile with the mounting space available on your balancer.

Match the spacer to your mounting setup

Check your balancer's model, faceplate arrangement, cone and shaft clamping space. Coats lists separate back-cone spacer options for different balancer models, so a nominal shaft size alone does not confirm compatibility. This listing does not identify a verified Coats model list or supply a complete truck-cone kit.

This is a wheel-balancer mounting accessory. Its dimensions describe the pictured spacer; no material grade, load rating or balancing-accuracy claim has been confirmed.
