Makita Genuine 151745-4 Tension Roller arm Complete for Makita 9404 Belt Sander

The Makita 151745-4 Tension Roller Arm Complete is a genuine OEM replacement part designed to restore correct belt tensioning and tracking on the Makita 9404 belt sander.

Supplied as a complete assembly, the unit includes the roller fitted to a robust metal arm, allowing straightforward like-for-like replacement of a worn or damaged component. Built to Makita factory specifications, it ensures an accurate fit and reliable operation consistent with original tool performance.

Maintaining proper belt tension is essential to smooth, consistent sanding results. This replacement part helps prevent belt slippage, edge fray, and uneven wear — common issues when the tension roller arm becomes worn through regular site or workshop use. By restoring correct tracking, it also supports more even finishes on timber and other materials.

For carpenters, joiners, and other tradespeople reliant on the Makita 9404, sourcing a genuine replacement rather than an aftermarket alternative ensures compatibility and dependability. The part is equally suitable for scheduled preventative maintenance, helping to avoid unplanned tool downtime on site.
