306.01.0007.02 Clutch Servo Repair Kit compatible with Mercedes-Benz

What does a clutch servo repair kit do?

A clutch servo repair kit is a service set that brings together the wear components—such as seals, O-rings, and dust boots—of the clutch servo found in a heavy commercial vehicle's hydraulic circuit. The clutch servo converts hydraulic pressure into mechanical motion to engage the clutch fork or release bearing. Replacing these components is an economical way to maintain the system when the cylinder bore remains in good condition.

Compatible Mercedes-Benz and Ford models

This kit is compatible with several Mercedes-Benz models including the NG series (1622 L, 2228, 1633, etc.), ATEGO 2 (1728 S, 2422), and OH series (1622 L, 1519). It also fits Ford Trucks models like the Cargo 2517, 2520, and 3227, as well as various Volkswagen Truck and DAF applications. The kit ensures compatibility with systems requiring precise sealing to prevent pressure loss during gear shifts.

Maintenance and installation guidance

When performing maintenance, technicians should verify the cylinder bore diameter and ensure the new seals are compatible with the hydraulic fluid used in the vehicle. It is critical to inspect the piston surface; if scoring or corrosion is present, a complete replacement of the servo unit is recommended over a repair kit to prevent future leaks. For optimal results, ensure all air is bled from the hydraulic circuit after installation.

Troubleshooting and selection

Maintaining the clutch actuation system is vital for preventing downtime in fleet operations. Regular inspection of the dust boot and seal integrity can prevent moisture ingress and premature component failure.
