WHAT DOES A LOWER BUSHING DO?
It centers the tool at the front head outlet, absorbs lateral loads and reduces wear on the tool and body. The right bore keeps tool play and lateral loads under control.
Other names used for this part include lower tool bushing, front bush and wear bush.
INSTALLATION AND MAINTENANCE NOTES
- Check the tool's lateral play regularly; increasing play is the first sign of bushing wear.
- If the play exceeds the wear limit in your manual, replace the bushing and the seal kit together; replacing only the seal is a temporary fix.

Frequently Asked Questions
Q: Does this lower bushing fit my Komac KB3000 breaker?
A: It is manufactured for the Komac KB3000. The same model may have been built with different designs in different production years or housing types, so please send us the dimensions of your existing bushing or the OEM part number before ordering.
Q: When should the lower bushing be replaced?
A: When the tool's lateral play exceeds the wear limit in your breaker's manual. If the breaker leaks oil at the tool end, measure the play first: above the limit, replace the bushing and the seal kit together; below the limit, replacing only the seal kit is enough. The limit depends on the model, so check your manual or send us the model code.
