A hydraulic breaker rarely gives you a warning before downtime becomes expensive.
A worn bushing.
A damaged retainer.
A tired accumulator membrane.
A seal that has started to fail.
Individually, they may look like small problems.
But inside a hydraulic breaker, small problems rarely stay small.
That’s why the K10088 Tune-Up Kit brings the critical maintenance components together in one complete solution.
The kit includes a lower tool bushing, tool retainer pin(s) or retainer bars, accumulator membrane, and complete sealing kit — giving you the essential components needed to restore and maintain breaker performance.
Instead of waiting for the next component to fail, you can take care of the critical wear points together.
Less searching for individual parts.
Less unnecessary downtime.
More confidence when the breaker goes back to work.
Because preventive maintenance isn’t just about protecting a breaker.
It’s about protecting the work the breaker is there to do.
K10088 Tune-Up Kit
One kit. Critical maintenance covered.
Keep your breaker ready for the next job.
