85102142 Compatible Clutch Servo Repair Kit — Volvo

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the sealing elements within the clutch hydraulic circuit, helping to restore smooth and reliable actuation. By replacing worn seals and O-rings, technicians can restore performance to the clutch system effectively. This kit is a cost-efficient solution when the cylinder bore and piston remain within service limits.

Compatible Volvo models and engines

This component is specifically fitted to Volvo FM and FMX II trucks, including models such as the FM 410, FM 460, and FMX 460. It also serves various other configurations within the FM series like the FM 370 and FM 450, ensuring compatibility across a wide range of heavy commercial vehicle applications.

Installation and maintenance guidance

During installation, workshop technicians should verify the cylinder type and seal orientation to ensure a correct fit. It is essential to follow proper lubrication and bleeding procedures to maintain system integrity. If the internal cylinder bore shows signs of excessive wear or scoring, replacing the entire unit may be a more durable long-term solution.

Troubleshooting and replacement

Maintaining the clutch servo ensures consistent pressure delivery during gear shifts. Regularly inspecting seals and boots can prevent air ingress and subsequent system failure in heavy-duty operating environments.
