Product Description

The 3M 7100089734 is a repair kit designed to restore a 3M File Belt Arm 28371 to proper working condition. The kit includes a contact wheel, two bearings, a shaft, and a platen pad — all the wear components typically required when the file belt arm loses smooth belt tracking or develops excessive play. This kit is intended for use by maintenance technicians, metalworking professionals, and industrial trades who rely on file belt arms for deburring, grinding, and finishing work in production or repair environments.

This repair kit applies specifically to the 3M File Belt Arm model 28371. It is suited for shops and facilities that run abrasive belt operations and need a reliable source of internal replacement components to minimize tool downtime. The included contact wheel and platen pad address both belt-contact and workpiece-support wear, while the bearings and shaft cover rotational component failure — making this a complete internal rebuild solution for that specific arm model.
