21008344 S3 Volvo FH Clutch Servo Repair Kit Equivalent

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the critical sealing elements that experience wear within the clutch hydraulic or pneumatic circuit. By replacing these components, workshop technicians can restore clutch actuation to its original performance levels, providing a cost-effective solution for heavy-duty vehicle maintenance.

Compatible Volvo heavy commercial vehicles

This kit is specifically compatible with Volvo FH models (including 400, 420, 440, 460, 480, 500, 520, 540) and Volvo FH16 II variants (such as FH 16/540, FH 16/550, FH 16/600, and FH 16/700). It ensures the integrity of the servo system in these heavy commercial vehicles.

Installation and maintenance guidance

During installation, technicians should verify the cylinder type and ensure correct seal orientation to prevent leaks. For optimal results, it is essential to follow proper lubrication and bleeding steps. If the internal piston or bore shows significant scoring or exceeds service limits, replacing the complete unit may be necessary for long-term reliability.

Troubleshooting and replacement advice

Maintaining the clutch servo is vital for smooth gear shifting and reducing pedal effort in heavy-duty applications. Consult your authorized distributor for fitment verification.
