Detailed Product Description

The Luk Clutch Master Cylinder LMC525 is a new replacement part engineered to restore proper clutch function in Mercedes-Benz 300D and 300TD vehicles. This component is critical in the hydraulic clutch system, transferring driver input from the clutch pedal to the clutch slave cylinder. The LMC525 comes with a push rod included, which is necessary for connecting the master cylinder to the clutch pedal assembly. While the product does not include a clutch slave cylinder or heat shield, it is designed to integrate seamlessly with existing components in the vehicle’s manual transmission system. Installation instructions are provided to assist with proper setup, although the system is not pre-filled with fluid nor pre-bled, so bleeding the clutch system after installation is required.

Installation Notes and Tips

When installing the Luk Clutch Master Cylinder LMC525, ensure the hydraulic system is properly bled to remove air and achieve optimal clutch performance. The included push rod should be securely connected to the clutch pedal assembly. Follow the provided installation instructions carefully to avoid damage to the new part or surrounding components. Since the master cylinder is not pre-filled or pre-bled, take extra care during the bleeding process to prevent air pockets in the hydraulic line.
