21206430 S2 Clutch Servo Repair Kit for Volvo FH13

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the essential sealing elements within the clutch hydraulic circuit. By replacing worn O-rings and seals, the kit helps restore clutch actuation to its original performance levels, providing an economical solution for maintaining heavy commercial vehicle systems.

Compatible Volvo FH models and engines

This component is specifically designed for Volvo FH series trucks, including models such as the FH460, FH540, and FH440, as well as the FH13 equipped with D13B engines. It ensures precise pressure distribution within the clutch servo assembly to maintain consistent pedal feel and gear engagement.

Installation and maintenance guidance

For optimal results during installation, technicians should verify that the cylinder bore is within service limits before proceeding. It is critical to follow correct seal orientation and lubrication procedures during assembly to prevent premature wear. If the internal piston surface shows significant scoring, a complete unit replacement may be required.

Troubleshooting and selection

Maintaining the clutch servo system through regular seal inspection helps prevent air ingress and hydraulic fluid leaks. This proactive maintenance is vital for the operational reliability of Volvo FH series heavy commercial vehicles.
