21564394 Volvo FM13 D13C Clutch Master Cylinder

This clutch master cylinder functions as a critical component in the hydraulic clutch control line. It is engineered to convert the mechanical force applied to the clutch pedal into precise hydraulic pressure, which is then transmitted via the hydraulic line to the slave cylinder to facilitate smooth gear engagement.

This specific unit is designed for Volvo FM13 trucks featuring D13C engines. It is built using high-strength components to withstand the demanding operating conditions of heavy commercial vehicles, ensuring long-term durability and consistent performance under high pressure.

For proper maintenance, technicians should inspect the hydraulic lines and seals regularly to prevent pressure loss. When replacing this unit, ensure that the mounting and connections are tightened to specification to maintain system integrity. Consult your authorized distributor.

The right part is identified by matching the OE reference number on the housing together with piston bore, stroke, port thread and mounting-hole spacing.
