Genuine Makita replacement pulley (part no. 222147-2) — listed as "Pulley 10-24.1" — designed to restore reliable drive and belt tracking on Makita belt sanders. This precision-machined drive wheel replaces a worn or damaged pulley to stop slippage, reduce vibration and protect the belt and bearings so your sander returns to smooth, consistent sanding performance.
Compatible with Makita 100 mm belt sanders (4" belt width) — commonly found on models such as the 9403 and 9921. If the pulley on your sander is cracked, rounded or has a worn bore, swapping in this genuine Makita part will restore correct belt tension and tracking.
Straightforward to fit with basic hand tools: the part is sold individually, made to Makita fitment standards and is an exact replacement that keeps your Makita parts inventory tidy and your tool working like new again. Installation generally involves removing the belt and the old pulley, fitting the new pulley to the shaft, and reassembling per the tool’s service instructions.
