Compatible Dynafile Contact Arm
The Dynabrade 11218 contact arm assembly fits Dynafile models 11X732 and 11X731. It provides a replacement arm for these specific pneumatic belt tools. Builders maintaining these exact machines will find the correct interface and mounting points.
Included Bearings And Shaft
The package supplies two bearings, a shaft, a contact wheel assembly and a soft platen pad. These components arrive pre-assembled so the arm can be fitted without sourcing separate hardware. The crowned rubber wheel and soft pad combine to give a forgiving contact surface on contoured workpieces.
Direct Bolt-On Installation
Installation consists of removing the old arm and bolting this unit to the existing tool body using the supplied shaft and bearings. No special tools are required beyond standard wrenches. The only common issue is overlooking the soft platen density when a firmer backing is needed for flat stock.

Questions about this item
When should the rubber contact wheel and platen pad on the 11218 arm be replaced?
Replace them when the crowned rubber wheel shows flat spots, the 3/8 in wheel width wears unevenly, or the soft platen pad no longer supports the 1/2 in belt evenly.
What stops the 11218 assembly from running continuously on a Dynafile 14000?
Heat buildup in the two included bearings and the rubber wheel limits continuous run time before the arm needs a cool-down period.
How much vibration and heat does the 11218 arm add during all-day use?
The 0.16 weight arm with rubber wheel and soft platen runs cool and transmits minimal vibration through the crowned 5/8 in wheel during extended sanding.
