7421965253 S2 Clutch Servo Repair Kit for Renault Trucks KERAX

What does a clutch servo repair kit do?

This clutch servo repair kit is designed to renew the essential sealing elements within the clutch hydraulic circuit, ensuring reliable gear shifting and actuation. By replacing worn O-rings, seals, and dust boots, this kit provides an economical solution for maintaining the clutch slave cylinder without replacing the entire unit.

Vehicle and engine compatibility

This specific service kit is compatible with Renault Trucks KERAX models, including various configurations such as the 410.18, 460.32, 500.32, and others utilizing the DXi engine. It also fits a wide range of Renault Trucks K series vehicles, including the 380T, 460P, 430T, and 520P variants across medium and heavy-duty applications.

Installation and maintenance guidance

During installation, technicians should verify the cylinder bore diameter and ensure the use of the correct hydraulic fluid class to prevent elastomer swelling. It is recommended to inspect the piston surface for scoring; if the bore or piston is damaged, a complete cylinder replacement may be required instead of a seal-only kit.

Troubleshooting and selection

Maintaining the clutch actuation system helps prevent sudden gear engagement issues and ensures smooth operation of heavy commercial vehicle drivetrains.
