21206430 S2 Clutch Servo Repair Kit for Volvo FM13

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to restore the efficiency of the clutch actuation system by renewing the sealing elements that undergo frequent wear. By replacing worn O-rings and seals, technicians can return the clutch servo to its original performance levels, ensuring smooth gear transitions and consistent pedal feel under heavy loads.

Compatible Volvo FM series vehicles

This component is specifically fitted to Volvo FM series trucks, including various models such as the FM 300, FM 340, FM 360, FM 370, FM 380, FM 390, FM 400, FM 410, FM 420, FM 430, FM 440, FM 450, FM 460, FM 480, and the FM 500. It is designed for compatibility with Volvo FM13 trucks equipped with D13A engines.

Installation and maintenance guidance

During installation, workshop technicians should verify the cylinder type and ensure that the bore surface is free of scoring. It is essential to follow correct lubrication and bleeding procedures to prevent air from entering the hydraulic circuit. Proper seal orientation is critical to prevent pressure loss during gear shifts.

Troubleshooting and selection

If the cylinder bore shows significant wear or damage beyond service limits, replacing the complete servo unit may be a more durable long-term solution than a seal kit alone.
