Makita 231490-8 Spare Part - COMPRESSION SPRING 5 BO6050
Genuine Makita compression spring – part no. 231490-8. This small compression spring (catalogued as “Compression Spring 5”) is the original Makita replacement used in several internal assemblies — for example it appears in the BO6050 150 mm random-orbit sander parts breakdown (under the change‑knob / change‑plate assembly) and is also shown in the AN8300 pneumatic framing nailer parts diagram.
Sold as a single, factory Makita spare, this spring restores the correct preload and tactile return for the change/guide parts it serves, so the knob, plate or related mechanism moves and seats correctly again. It’s a direct fit where the parts diagrams list 231490-8.
Fits (examples): Makita BO6050 (random orbit sander) and Makita AN8300 (pneumatic framing nailer) — referenced in the official parts breakdowns. If your model’s parts diagram shows 231490-8 or “Compression Spring 5,” this is the matching genuine Makita replacement.
