970 051 412 0 S1 WABCO compatible Clutch Servo Repair Kit

What does a clutch servo repair kit do?

This clutch servo repair kit serves as a critical maintenance component for the clutch actuation system. By replacing worn seals and O-rings, it helps maintain the necessary hydraulic or pneumatic pressure required for smooth gear engagement in heavy commercial vehicles.

Compatibility and application

This component is compatible with WABCO systems. It is specifically designed to restore functionality to the clutch servo, ensuring the actuation mechanism operates within standard parameters to prevent pressure loss.

Installation and maintenance guidance

Technicians should inspect the cylinder bore and piston surface before installation. If the piston surface is scored, a complete kit including a piston and pushrod may be required instead of a standard sealing kit. Always ensure all O-rings are properly lubricated during assembly to prevent premature leaks.

Troubleshooting and selection

Regular inspection of the dust boot and seals can prevent air or fluid contamination from entering the cylinder, extending the service life of the entire clutch servo assembly.
