Contact Arm Assembly 11287

This Dynabrade contact arm assembly fits model 11X735 tools. It accepts belts that are 5/8 in or 3/4 in wide and 20 1/2 in long. The rubber wheel measures 3/4 in diameter by 5/8 in width. A 3/4 in platen is included with the assembly.

Rubber wheel and included platen

The rubber contact wheel provides a compliant surface for finishing and blending tasks. Its 3/4 in by 5/8 in profile suits contoured workpieces where a rigid wheel would bridge low spots. The supplied platen supports the belt behind the wheel for flat-area sanding without swapping components.

Upgrade for worn 11X735 arms

This assembly replaces a damaged or hardened original arm on the 11X735. The jump is worth it when the existing wheel no longer tracks belts true or the rubber has lost resilience. It is not for tools outside the 11X735 series or for applications needing a steel or serrated wheel.

Questions about this item

Which belts fit the 3/4 in x 5/8 in rubber contact arm?

It accepts belts 5/8 in (16 mm) or 3/4 in (19 mm) wide by 20 1/2 in (521 mm) long.

What mounting hardware is required to attach this arm to the 11X735 tool?

The assembly includes a 3/4 in platen and mounts directly to the 11X735 without extra brackets.

How is the contact arm installed on the 11X735, and what step is often missed?

Remove the old arm, fit the new rubber wheel assembly with the included platen, then tension the belt — forgetting to re-tension after the first run is the common error.
