21206430 S3 Compatible Volvo FMX D13K Clutch Servo Kit

What does a clutch servo repair kit do?

This clutch servo repair kit serves as a vital component for maintaining the pneumatic or hydraulic actuation of the clutch system. By replacing worn seals and internal components, it ensures smooth gear engagement and prevents pressure loss within the clutch servo mechanism. This high-strength component helps prevent premature failure of the entire assembly during heavy-duty operations.

Compatible Volvo vehicles and engines

The kit is designed for compatibility with Volvo FMX trucks equipped with D13K engines, as well as various Volvo FM series models including FM 460, FM 480, FM 440, and FM 340. It is also suitable for other FM variants such as FM 450, FM 500, FM 370, FM 300, FM 330, FM 360, FM 410, FM 430, FM 390, FM 400, FM 380, and FM 420.

Installation and maintenance guidance

When performing maintenance, technicians should inspect the cylinder bore and piston surface to determine if a sealing kit is sufficient or if a complete piston assembly is required. For external-type cylinders, ensuring the dust boot and pushrod integrity is essential to prevent contamination. Regular inspection of the seals and O-rings can prevent costly downtime in heavy commercial vehicle fleets.

Troubleshooting and selection

Selecting the correct repair kit ensures that the clutch actuation remains consistent under high pressure. Consult your authorized distributor to confirm specific fitment requirements for your vehicle's engine configuration.
