Description
Overview:
The Makita Ring Spring is a small but vital service part used in the hammer/anvil assembly of Makita impact wrenches to maintain correct tension and component alignment. Made from hardened spring steel for resilience under repeated load, it helps ensure consistent torque delivery and smooth operation. This Genuine Makita part, MPN 231907-1, is designed as a like-for-like replacement for worn or fatigued springs in a wide range of models, including 6911HD and 6918D. Suitable for both corded and cordless impact wrenches, the ring spring supports reliable engagement of the striking mechanism, helping to restore performance and extend tool life. It is ideal for routine maintenance or repairs where power output has become inconsistent due to spring wear.
Key Features:
- Genuine Makita part for fit, function, and durability
- Hardened spring steel construction to withstand heavy-duty use
- Maintains correct preload in the hammer/anvil mechanism for consistent torque
- Direct replacement to restore performance and reliability
- Designed to fit a wide range of Makita impact wrenches
- Compact form for straightforward installation with basic hand tools
- Helps reduce rattle, backlash, and premature wear in the drive assembly
- Supports smooth, efficient operation under repeated impact cycles
Typical Applications:
Used during service or repair of Makita impact wrenches where the striking mechanism shows reduced drive, excess play, or irregular torque. Ideal for workshop maintenance, on-site tool servicing, and fleet upkeep across automotive, construction, fabrication, and plant hire environments. Replacing a tired ring spring helps recover fastening performance and prolongs the life of mating parts.
