Description
Overview:
The Makita Ring Spring (MPN 233940-9) is a genuine replacement part for Makita rotary hammer drills, including popular models such as BHR241 and BHR261. This compact circular spring is made from tough spring steel with a black protective finish, designed to hold critical front-end components in correct tension so the tool runs smoothly. In service, it helps maintain secure seating of parts within the tool holder/hammer mechanism, reducing play and improving consistency under load. If your drill has developed looseness, intermittent operation, or components are not retaining as they should, replacing a fatigued or damaged ring spring can restore performance. Designed to the original Makita specification, it fits like-for-like in compatible tools for a reliable, long-lasting repair.

- Black protective finish to help resist wear and corrosion
- Maintains correct tension in the tool's front-end assembly
- Helps restore smooth operation and reduce unwanted play
