306.01.0041.02 Repair Kit for Clutch Servo compatible with Volvo

What does a clutch servo repair kit do?

A clutch servo repair kit is a specialized set of components used to refurbish the clutch actuation unit. These kits are essential when the cylinder bore remains in good condition but the seals or O-rings have failed. By renewing these high-strength components, workshop technicians can restore hydraulic or air-assisted pressure without replacing the entire assembly.

Compatible vehicles and engines

This kit is compatible with a wide range of heavy commercial vehicles, including Volvo FH (FH4/FH5), FM, FMX, and FE series, as well as Renault Trucks Premium and Magnum models. It is also suitable for various engine configurations such as D13, D11, and DXi11, ensuring precise clutch disengagement across diverse fleet operations.

Installation and maintenance guidance

When performing maintenance, technicians should verify the cylinder type—whether external, concentric, or air-assisted—before selecting the kit. It is critical to ensure that the internal bore surface is free from scoring or corrosion; if the bore is damaged, a complete unit replacement is recommended instead of a kit. Always use the correct hydraulic fluid as specified by the manufacturer to prevent elastomer swelling.

Selection and troubleshooting

Check the compatibility list to ensure this kit matches your specific vehicle model and engine requirements.
