20553587 Compatible Clutch Master Cylinder — Volvo FMX

What does a clutch master cylinder do?

This clutch master cylinder serves as a critical component within the hydraulic clutch system, converting the mechanical force from the pedal into hydraulic pressure. This pressure is then transmitted through the line to the slave cylinder to facilitate smooth gear engagement. Built with high-strength components, it ensures durability under the demanding operating conditions of heavy commercial vehicles.

Vehicle and engine compatibility

This unit is engineered for fitment in Volvo FMX trucks powered by the D13C engine. It is also compatible with various other heavy-duty vehicle applications requiring similar hydraulic specifications. For precise selection, ensure the port size and mounting dimensions align with the existing system requirements.

Installation and maintenance

Technicians should inspect the Ø28.57 mm port and the sealing group during installation to prevent pressure loss. To ensure proper function, check the push rod and housing for any signs of wear or fluid leakage during routine maintenance intervals.

Troubleshooting and selection

When replacing a faulty unit, it is recommended to verify all mounting dimensions and port sizes to ensure seamless integration into the vehicle's clutch system.
