22327063 Volvo FH Clutch Servo

What does a clutch servo do?

This clutch servo plays a critical role in the hydraulic actuation system of the transmission, providing the necessary force to ensure smooth and complete clutch disengagement. Built with high-strength components, it is engineered to withstand the rigorous operating conditions typical of heavy commercial vehicle service.

Vehicle and engine compatibility

This component is specifically fitted to Volvo FH models, including the FH4 and FH5 series powered by the D11K engine. It serves a wide range of variants such as the 400, 420, 440, 460, 480, 500, 520, and 540 models. For correct selection, the vehicle model, chassis number, and whether the clutch system is hydraulic or cable-actuated must be verified; the piston bore and stroke within the complete assembly must be compatible with the master cylinder.

Installation and maintenance guidance

When replacing this unit, technicians should verify that the piston bore match is correct to maintain proper pedal feel and release travel. It is also vital to ensure that the connection interface geometry matches the existing lever or fork to prevent uneven wear or engagement issues.

Troubleshooting clutch actuation

Regular inspection of the hydraulic lines and connection points can prevent premature failure. If pedal travel feels inconsistent or if there is any loss of pressure in the actuation circuit, consulting your authorized distributor is recommended.
