21008344 S3 Compatible Volvo FH16 D16K Clutch Servo Repair Kit

What does a clutch servo repair kit do?

This clutch servo repair kit is designed to restore the efficiency of the clutch actuation system by renewing the critical sealing elements that experience wear over time. By replacing the internal seals and O-rings, technicians can restore hydraulic pressure and smooth engagement without replacing the entire unit, provided the cylinder bore remains within service limits.

Compatible Volvo trucks and engines

This specific kit is compatible with Volvo FH series trucks, including models 400, 420, 440, 460, 480, 500, 520, and 540. It is also specifically fitted to Volvo FH16 trucks equipped with D16K engines. These components are essential for maintaining the reliability of the clutch system in heavy-duty operation.

Installation and maintenance guidance

During installation, workshop technicians should verify the cylinder type and seal orientation to ensure a proper fit. It is recommended to check for bore scoring before assembly; if the piston surface is damaged, a complete unit replacement may be more effective. Always follow standard lubrication and bleeding procedures to prevent air from entering the hydraulic circuit.

Troubleshooting and selection

Maintaining the clutch servo through regular inspection helps prevent unexpected downtime in heavy commercial vehicles. Consult your authorized distributor for further information.
