306.02.0071 Master Cylinder for Volvo and Renault Trucks

What does a clutch master cylinder do?

This clutch master cylinder is a critical component within the hydraulic control line of the clutch system. It functions by converting pedal force into precise hydraulic pressure, which is then transmitted through the hydraulic line to the slave cylinder to facilitate smooth gear changes. Built with high-strength components, it ensures consistent performance even under the demanding operating conditions typical of heavy commercial vehicle use.

Vehicle and engine compatibility

The unit is compatible with a wide range of heavy commercial vehicle models, including Volvo FH12, FH13, FM series, and VNL series engines like D13A and D11B. It also fits Renault Trucks Kerax and Magnum models, as well as Mack Granite and Pinnacle trucks. Additionally, it is fitted to DAF and Iveco vehicles.

Installation and maintenance guidance

For optimal performance, technicians should inspect the Ø28.57 mm port connection during installation to ensure a secure hydraulic seal. Regular maintenance of the hydraulic fluid and inspection of the seals can prevent system failure and ensure predictable clutch engagement. Consult your authorized distributor to confirm exact fitment for your specific engine configuration.

Selection guidance

When selecting a replacement, ensuring compatibility with the specific engine type—such as the Volvo D16 or Renault DXi13—is essential for maintaining system integrity.
