21206430 S3 Clutch Servo Repair Kit for Volvo FM Series

What does a clutch servo repair kit do?

This clutch servo repair kit is essential for maintaining the hydraulic or air-assisted actuation of the clutch system. Designed to restore the sealing integrity of the clutch servo, these components help prevent pressure loss and ensure smooth gear transitions in heavy commercial vehicles. Using high-strength components helps extend the service life of the existing cylinder assembly.

Compatible Volvo FM models and engines

This kit is specifically compatible with Volvo FM series trucks, including models such as the FM 460, FM 480, FM 440, and FM 340. It is also fitted to Volvo FM trucks utilizing the D11A engine. This ensures that workshop technicians can perform precise repairs on various heavy-duty configurations within the FM range.

Installation and maintenance guidance

When performing maintenance, technicians should inspect the cylinder bore and piston surface to determine if a sealing kit or a complete kit is required. If the piston surface is scored, a full piston assembly may be necessary. For optimal performance, ensure all surfaces are clean and free of debris during installation to maintain system pressure.

Troubleshooting and selection

Regular inspection of the seals and dust boots can prevent larger system failures. Maintaining these components helps prevent air or fluid contamination within the clutch actuation circuit.
