21710522 S1 Volvo FH Series Clutch Servo Service Kit

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the essential sealing elements within the clutch hydraulic circuit, restoring smooth actuation to the vehicle's clutch system. By replacing worn seals and O-rings, technicians can effectively address leaks and pressure loss without replacing the entire unit, making it a highly efficient maintenance solution for heavy commercial vehicles.

Compatible Volvo truck models

This specific kit is designed for use in Volvo FH and FH16 II models, including variants such as the 440, 480, 520, and 540, as well as FH 16/700 and FH 16/550 series. It ensures compatibility with these specific engine and chassis configurations to maintain optimal gear engagement.

Installation and maintenance guidance

During installation, workshop technicians should verify the cylinder type and seal orientation against the original component. It is critical to ensure proper lubrication and complete bleeding of the hydraulic system to prevent air pockets that could compromise clutch performance. For cylinders showing significant internal scoring, a complete unit replacement may be required.

Maintenance and troubleshooting

Regular inspection of the clutch servo seals helps prevent premature wear on the release bearing and gearbox components. Maintaining the integrity of the hydraulic circuit ensures reliable operation for fleet managers and service providers alike.
