306.01.0011.05 Compatible Clutch Servo Repair Kit

What does a clutch servo repair kit do?

A clutch servo repair kit restores the performance of the clutch actuation system by renewing worn sealing elements. These kits are essential for maintaining precise pedal feel and ensuring smooth gear engagement in heavy commercial vehicles. Using high-strength components helps prevent pressure loss within the hydraulic or pneumatic circuit.

Compatible vehicles and engines

This kit is specifically designed for Mercedes-Benz ACTROS MP2/MP3, AXOR, and UNIMOG trucks. It is compatible with engines such as the OM 501 LA, OM 502 LA, and OM 457 LA series. Additionally, it is fitted to PACCAR vehicles in certain configurations. Always verify the cylinder bore diameter and type before installation to ensure correct fitment.

Installation and maintenance

When performing maintenance, technicians should inspect the cylinder bore for scoring or corrosion. If the internal surface is damaged, a complete unit replacement is recommended over a repair kit. During installation, ensure correct seal orientation and proper bleeding of the system to prevent air pockets that cause soft pedal feel.

Troubleshooting and selection guidance

For optimal results, compare the kit specifications against the original unit removed from the vehicle. This ensures that the seal diameter and pushrod length match the original requirements of the Mercedes-Benz or PACCAR systems.
