85102142 Volvo FH Series Clutch Servo Kit

What does a clutch servo repair kit do?

This clutch servo repair kit is designed to renew the sealing elements that wear out most often in the clutch hydraulic circuit, restoring actuation to its original performance. Utilizing heavy-duty grade materials, this kit ensures durability under the high-pressure conditions typical of heavy commercial vehicle operation.

Vehicle and engine compatibility

This specific kit is compatible with Volvo FH12 models including the 460, 420, and 380 variants, as well as various Volvo FH configurations such as the 400, 500, 420, 440, and 460. It is specifically engineered for use with D12D engines to maintain precise engagement.

Installation and maintenance guidance

For a successful installation, workshop technicians should verify the cylinder type and seal orientation before proceeding. It is essential to ensure proper lubrication and bleeding during the assembly process to prevent air from entering the hydraulic circuit. If the cylinder bore shows signs of scoring or is beyond service limits, a complete unit replacement may be required.

Troubleshooting and selection

Maintaining the clutch servo ensures smooth gear transitions and prevents premature wear on the release bearing and gearbox components. Consult your authorized distributor to ensure exact fitment for your specific vehicle configuration.
