Makita STRAP WASHER 9401/9402 - 341079-5
Genuine Makita 341079-5 — Strap washer for Makita 100 mm (4") belt sanders, commonly used on models 9401 and 9402.
A stamped metal strap-style washer with four mounting openings that sits between the steel pressure plate and the fixing screws, holding the cork/rubber platen and frame at the correct spacing for smooth belt tracking — a small, low-cost part for power tools that prevents looseness and premature wear.
As part of genuine Makita parts, 341079-5 is listed in Makita service diagrams and parts price lists simply as “washer” (PN 341079-5); it’s made to original factory tolerances so it fits directly into the 9401 / 9402 assembly and can be refitted with standard hand tools.
If your 100 mm × 610 mm belt sander is showing belt-tracking issues or a loose platen, replacing the 341079-5 strap washer restores the correct spacing and alignment quickly — a straightforward repair to get the tool back to reliable operation.
