Cummins®

The Cummins 3871517 Slave Piston is a component designed for use in commercial trucks. It plays a role in the clutch system by facilitating the disengagement and engagement of the clutch, which is vital for smooth gear shifting and overall vehicle operation ³.

Basic Concepts of Slave Pistons

A slave piston is a component within a hydraulic clutch system that transmits force from the clutch master cylinder to the clutch release bearing. When the driver presses the clutch pedal, hydraulic fluid is sent from the master cylinder to the slave piston, causing it to move and apply pressure to the release bearing. This action disengages the clutch, allowing the driver to shift gears ¹.

Purpose and Role of the 3871517 Slave Piston

This Cummins part is specifically engineered for heavy-duty truck applications. It contributes to the efficient disengagement and engagement of the clutch by precisely controlling the movement of the release bearing. This ensures that gear changes are performed without undue stress on the transmission and other components, enhancing the overall performance and longevity of the truck’s drivetrain ³.
