The ATC 7900 Piston Ring Compressor is a precision-built installation tool designed specifically for the PACCAR MX13 heavy-duty diesel engine.
Engineered for optimal performance in professional rebuild shops and field service operations, this compressor simplifies piston and ring installation by securely compressing the rings and guiding the piston into the liner bore—helping reduce risk of ring breakage, liner scoring or piston damage.
Whether you're installing new pistons or performing a full engine rebuild, the ATC 7900 addresses the unique bore geometry and ring profiles of the MX13 series to deliver accurate and repeatable outcomes.
