Clutch Master Cylinder 19mm (Seger) (Mercedes-Benz Sprinter / Viano/Vito W638 / W639) is a critical hydraulic component that transmits the driver’s clutch pedal force to the clutch assembly, enabling smooth gear shifts. This particular unit is designed for use with Mercedes-Benz Sprinter, Viano, and Vito models within the W638 and W639 chassis ranges.
The master cylinder features a 19mm bore size and utilizes Seger technology, which ensures appropriate hydraulic pressure is generated to engage or disengage the clutch effectively. When replacing the clutch master cylinder, it is essential to verify the bore size and compatibility with the vehicle model to ensure proper operation and avoid clutch engagement issues.
This part is typically mounted near the clutch pedal inside the engine compartment, connected to the clutch pedal and the clutch slave cylinder via hydraulic lines. Buyers should compare their existing clutch master cylinder for bore size, overall condition, and design to confirm suitability.
Choosing the correct clutch master cylinder helps maintain smooth clutch functionality, preventing issues like pedal sponginess or incomplete disengagement. For any uncertainty about fitment or matching your vehicle’s requirements, consulting the sales desk or submitting a request for assistance through the provided channels is advisable.
