A0005861743 Clutch Servo Repair Kit for Mercedes-Benz NG

What does a clutch servo repair kit do?

This clutch servo repair kit serves as a critical service solution for restoring the hydraulic efficiency of the clutch actuation system. By replacing the internal wear components, this kit helps prevent pressure loss and ensures reliable mechanical motion during gear changes. It is engineered using heavy-duty grade materials to withstand the high-pressure environments found in heavy commercial vehicle hydraulic circuits.

Compatible vehicles and engines

This specific kit is compatible with Mercedes-Benz NG models, including the 2222 L, 1622 L, 2222, 1622, 1422 L, and 1422 variants featuring OM 421 engines. For accurate fitment, technicians should always verify the cylinder type and bore diameter against the original component removed from the vehicle.

Installation and maintenance

When performing installation, ensure the cylinder bore is free of scoring or deep scratches. It is essential to use the correct hydraulic fluid class and to carefully inspect the seal orientation during assembly to prevent immediate leaks. Proper lubrication of the new seals during installation is vital for long-term durability.

Troubleshooting and selection

Regular inspection of the clutch servo is recommended to identify early signs of fluid leakage or irregular pedal feel. If the cylinder body shows significant wear, a complete unit replacement may be more effective than a seal kit.
