Clutch Release Shaft
Mack

The clutch release shaft is a precision-driven component that translates pedal effort into clutch disengagement within manual or automated transmission systems. Manufactured from hardened alloy steel, it resists wear from repeated contact with the release bearing and actuation fork, ensuring consistent pedal feel and predictable clutch cycling. A well-made shaft minimizes play, reduces chatter during engagement, and extends the life of adjacent components such as the release bearing and pivot points. Its surface finish and straightness are engineered to maintain smooth engagement across a wide temperature range and road conditions typical of long-haul operations. When replacing, confirm compatibility with the transmission model, fork geometry, and bearing size. Proper fitment and lubrication are essential for quiet operation and reliable clutch disengagement. Installation typically involves aligning the shaft with the release fork, securing it with appropriate fasteners, and verifying full travel without binding. Source One Parts Center notes that this part is commonly specified for Mack trucks and emphasizes proper installer checks during service.
