Cummins®

The Cummins 3871442 Slave Piston is a component designed for use in commercial trucks. It plays a role in the clutch system, contributing to the efficient operation of the vehicle. Understanding its purpose and significance is important for maintaining the performance and reliability of commercial trucks.

Basic Concepts of a Slave Piston

A slave piston is a component within the clutch system that facilitates the engagement and disengagement of the clutch. It operates in conjunction with the master cylinder and the clutch release bearing. When the driver presses the clutch pedal, hydraulic fluid from the master cylinder exerts pressure on the slave piston, which then moves the release bearing to disengage the clutch. This allows for smooth gear changes ¹.
