What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the sealing elements that frequently wear out within the clutch hydraulic circuit. By replacing these critical components, the clutch actuation performance is restored to its original standards, providing a cost-effective solution for heavy commercial vehicle maintenance.

Compatible Volvo vehicles and models

This specific kit is compatible with various Volvo FM series models, including the FM 360, FM 370, FM 380, FM 390, FM 400, FM 410, FM 420, FM 430, FM 440, FM 450, and FM 460. It is also suitable for several Volvo FMX variants such as the 370, 410, 450, and 460 models. These components are essential for maintaining optimal gear shifting and pedal feel in heavy-duty applications.

Installation and maintenance guidance

For a successful installation, workshop technicians should verify the cylinder type and seal orientation against the removed part. It is critical to ensure proper lubrication and bleeding of the hydraulic system during assembly to prevent air pockets. If the cylinder bore shows significant scoring or damage beyond service limits, a complete unit replacement may be required.

Troubleshooting and selection

Maintaining the clutch servo ensures consistent pressure delivery within the actuation system. Using high-strength components helps prevent premature leaks and ensures long-term reliability under heavy load conditions. Check the compatibility list.
