21008344 S2 Volvo FMX D11K Clutch Servo Service Kit

What does a clutch servo repair kit do?

This clutch servo repair kit is designed to restore the efficiency of the clutch actuation system. By replacing worn seals and O-rings, technicians can maintain the hydraulic or air-assisted pressure required for smooth gear transitions and consistent clutch engagement in heavy-duty applications.

Compatible Volvo truck models

This kit is specifically compatible with Volvo FMX models equipped with D11K engines, as well as a wide range of Volvo FM series trucks including the FM 300, FM 340, FM 360, FM 370, FM 380, FM 390, FM 400, FM 410, FM 420, FM 430, FM 440, FM 450, FM 460, FM 480, and FM 500. It serves as an economical solution for maintaining the clutch servo when the cylinder bore remains in good condition.

Installation and maintenance guidance

For optimal performance, workshop technicians should inspect the cylinder bore and piston surface during installation. Ensuring that all mounting points are clean and that the new seals are properly seated will prevent future pressure leaks. Regular inspection of the dust boot and O-rings is recommended to prevent contaminants from entering the system.

Ensuring system reliability

Using high-strength components helps prevent sudden loss of pressure which can lead to difficult gear shifts or slipping. Check the compatibility list to ensure this kit meets your specific engine requirements.
