21008344 S1 Volvo FM D13C Clutch Servo Repair Kit

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the sealing elements that experience frequent wear within the clutch hydraulic circuit. By replacing these critical components, technicians can restore clutch actuation to its original performance levels at an efficient cost. The kit is designed to withstand the rigorous operating conditions typical of heavy commercial vehicle systems.

Compatible Volvo FM models and engines

This specific repair kit is compatible with Volvo FM series trucks, including models such as the FM 480, FM 450, and FM 420, as well as the FM 300 through FM 500 range. It is specifically tailored for applications utilizing the D13C engine. This ensures precise fitment and optimal pressure maintenance within the actuation system.

Installation and maintenance guidance

For successful installation, workshop technicians should verify the cylinder type and seal orientation against the removed part. It is essential to ensure proper lubrication and bleeding of the hydraulic system during assembly to prevent air pockets. Using high-strength components helps maintain consistent engagement and pedal feel.

Troubleshooting and replacement advice

If the cylinder bore shows signs of excessive scoring or damage, replacing the complete servo unit is recommended for a more lasting solution. However, when the piston and bore remain within service limits, this kit provides a robust maintenance option.
