306.01.0011.02 Mercedes-Benz Compatible Clutch Servo Repair Kit

What is a clutch servo repair kit?

A clutch servo repair kit is a set of sealing elements used to refurbish clutch slave cylinders when the internal bore remains in good condition. These kits typically include high-strength seals, O-rings, and dust boots to restore the hydraulic integrity of the actuation system.

Compatible Mercedes-Benz models and engines

This kit is compatible with various Mercedes-Benz models including the Actros MP2 / MP3 (fitted with OM 501 LA and OM 502 LA engines), Axor and Axor 2 series (utilizing OM 457 LA), and Unimog vehicles (including OM 934 LA and OM 936 engines). It is also fitted to PACCAR trucks. For optimal results, verify that the kit's seal diameter matches the cylinder bore before installation.

Installation and maintenance guidance

During installation, technicians should ensure the cylinder bore is free of scoring or corrosion. If the piston surface shows signs of wear or the rod fails to return, a complete unit may be required instead. Always use the correct hydraulic fluid class as specified by the manufacturer to prevent elastomer swelling.

Troubleshooting and selection

Maintaining the clutch servo through regular seal replacement helps prevent pressure loss in the hydraulic circuit, ensuring smooth gear changes and consistent pedal feel for fleet managers and workshop technicians alike.
