Check the bore and available mounting space

Measure the shaft on your machine and check the adapter requirements in its manual. A Coats brand name alone does not confirm the shaft size or the correct backing plate.

The product's center-hole dimension graphic conflicts with the listed 28 mm shaft application. Confirm the actual bore before ordering rather than relying on that graphic. Plate outside diameter, recess depth and overall thickness are also unverified.

Compare the recessed face and outer rim with the mounting arrangement for your wheel. Check clearance for the selected cone and the space remaining on the shaft for secure clamping. The plate does not replace the centering cone or provide a wheel center-bore range by itself.

Use the mounting procedure for your balancer

Coats describes back-cone spacers as accessories that extend the faceplate for larger cones. Its catalog is guidance on the component's role, not a fitment or manufacturing specification for this replacement.

Use the cones and clamping parts required by your machine's instructions. Material grade, load capacity, machining tolerance and a verified balancer model list have not been supplied for this plate.
