23108445 S1 Clutch Master Cylinder for Volvo FM13

What does a clutch master cylinder do?

This clutch master cylinder serves as a critical component in the hydraulic control line, converting the mechanical force from 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 demanding operating conditions of heavy commercial vehicles.

Compatible vehicles and engines

This specific unit is compatible with Volvo FM13 models equipped with D13C engines. It functions as a complete assembly, ensuring that the housing, piston, and sealing group work in unison to maintain consistent hydraulic performance throughout the life of the component.

Installation and maintenance

When performing installation or maintenance, technicians should verify the Ø28.57 mm port specification and ensure all connections to the hydraulic lines are secure. Proper installation prevents air ingress into the system, which is vital for maintaining correct pedal feel and engagement depth.

Troubleshooting and selection

Regular inspection of the hydraulic lines and seals can help prevent pressure loss in the clutch system. If pedal travel changes or engagement becomes inconsistent, checking this unit is a recommended step for workshop technicians.
