What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the sealing elements that wear out most often in the clutch hydraulic circuit, restoring clutch actuation to its original performance at a low cost. These high-strength components ensure the system maintains proper pressure and responsiveness during operation.

Compatible Volvo FH models and engines

This kit is specifically fitted to Volvo FH (FH4/FH5) trucks, including variants such as the 400, 420, 440, 460, 480, 500, 520, and 540 models equipped with D13K engines. It serves as a precise replacement for original components to maintain heavy-duty performance.

Installation and maintenance guidance

For successful installation, workshop technicians should verify the cylinder type and seal orientation against the removed part. It is essential to ensure proper lubrication and bleeding of the hydraulic circuit during the assembly process to prevent air pockets. If the cylinder bore shows signs of excessive wear, a complete unit replacement might be necessary.

Troubleshooting and selection
