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. By replacing worn components, it helps restore smooth and precise clutch actuation, ensuring the vehicle maintains its original performance levels under heavy-duty service conditions.

Vehicle and engine compatibility

This specific kit is compatible with Volvo FH (FH4/FH5) models, including various engine configurations such as the D13K. It is specifically designed to fit Volvo FH series trucks with 400, 420, 440, 460, 480, 500, 520, and 540 specifications.

Installation and maintenance guidance

When performing installation, technicians should verify the cylinder type and seal orientation to ensure a proper fit. It is recommended to check for any scoring on the piston surface before installation; if the bore or piston is damaged, a complete unit replacement may be necessary for a lasting fix.

Regular maintenance of the clutch servo system helps prevent unexpected downtime in heavy commercial vehicles. Always ensure the hydraulic system is properly bled after the repair to prevent air pockets from affecting engagement quality.
