Description

What does a clutch master cylinder do?

This clutch master cylinder is a critical hydraulic component that converts the mechanical force applied to the clutch pedal into hydraulic pressure. This pressure is then transmitted through the hydraulic line to the slave cylinder to facilitate smooth gear engagement. Built with high-strength components, this unit is designed to withstand the rigorous operating conditions of heavy commercial vehicles.

Vehicle and engine compatibility

This specific unit is compatible with Scania 4-series trucks, including models such as the 114 C/340, 114 L/340, T 114 L/340, T 114 G/340, T 114 C/340, and 114 G/340. It is specifically engineered for applications utilizing the DSC 11 engine. The part is provided as a complete assembly, including the housing, piston, and sealing group to ensure seamless integration into the vehicle's clutch system.

Installation and maintenance guidance

For workshop technicians and fleet managers, replacing the unit as a single complete part is recommended over using repair kits when internal seals or the housing show signs of wear. When performing installation, ensure that all hydraulic lines are free of air and that mounting-hole spacing aligns perfectly with the existing assembly to prevent leaks or uneven pressure distribution.

Troubleshooting and replacement

Regular inspection of the hydraulic lines and fluid levels can help prevent premature failure of the clutch system. If a spongy pedal feel or difficulty shifting occurs, this master cylinder may require replacement to restore optimal hydraulic performance in heavy commercial vehicle fleets.

OE cross-reference

306.01.0003 (Master Cylinder) is the equivalent of the Scania OE number. This part directly replaces Scania OE number 1421186.
