K-4677CL Heavy-Duty Vocational Diaphragm Spring Clutch Kit, New

Product Overview

K-4677CL Heavy-Duty Vocational Diaphragm Spring Clutch Kit is designed for selected Endurant HD Vocational; Cummins L9 / PX9 applications. The diaphragm spring applies clamp load across the friction assembly, the driven disc transfers torque into the transmission, and the release system controls disengagement during automated shifts. Replacement may be considered when inspection finds lining wear, heat damage, release noise, contamination, excessive travel, or engagement problems.

This new independent aftermarket kit supports planned clutch service without changing the vehicle’s original powertrain design. Release-bearing style, damper dimensions, bore size, flywheel configuration, and control-system setup must all agree with the application.
