Vibration is part of the job with an air body saw, and over time the small hardware that holds key assemblies together can wear, loosen, or get damaged during servicing. A worn bushing can introduce unwanted play, while a tired or damaged cap screw can compromise clamping force—leading to misalignment, rattles, and reduced cutting control.

It’s the practical fix when you want the tool to feel tight and solid again, and it’s also a smart kit to keep on hand for workshop repairs where fast turnaround matters.

This kit focuses on the bushing and fastening components that support correct assembly and alignment—helping reduce movement and maintain reliable operation under vibration.
