85102142 Volvo NH12 D12C Clutch Servo Repair 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 clutch actuation to its original performance at low cost.

Compatible vehicles and engines

Specifically fitted for Volvo NH12 trucks equipped with D12C engines, this kit serves as a precise replacement for worn components. Using high-strength components ensures the system maintains pressure and prevents leaks during heavy-duty operation.

Installation and maintenance

For successful installation, technicians should verify the cylinder type and seal orientation before assembly. It is essential to ensure proper lubrication and follow correct bleeding steps to prevent air from remaining in the hydraulic circuit.

Troubleshooting and selection

If the cylinder bore shows signs of scoring or damage beyond service limits, replacing the complete unit is recommended over a seal kit to ensure long-term reliability.
