The Lucas CAV Cam Ring 7189-100BQ is a precision-engineered component used in Delphi / Lucas CAV rotary diesel injection pumps, specifically designed to control the movement of internal rollers and plungers within the pump. By converting rotational motion into reciprocating action, the cam ring ensures accurate fuel pressurization and injection timing, which is essential for stable engine performance and efficient combustion.
In terms of applications, the 7189-100BQ cam ring is widely used in Delphi DP210 and DP310 rotary injection pumps, as well as other CAV/Delphi pump systems commonly installed in diesel engines from brands such as Perkins, Ford, Massey Ferguson, and Fiat. These pumps are typically found in agricultural tractors, light commercial vehicles, and industrial diesel engines. The cam ring is also interchangeable with closely related part numbers such as 7189-100CA, 7189-100CE, and 7189-100AA, making it a flexible replacement option across multiple pump configurations.
Additionally, the 7189-100BQ is commonly supplied as part of a cam ring and scroll plate kit, used in diesel injection pump rebuilding and maintenance. Its compatibility with a wide range of Delphi/Lucas systems makes it a popular choice for restoring fuel pump performance in older mechanical diesel engines used in farming equipment, generators, and construction machinery.
Manufactured from high-strength alloy materials with advanced heat treatment, the Lucas CAV Cam Ring 7189-100BQ is built to withstand high mechanical stress and continuous operation. When replacing this component, it is essential to match the correct pump model and part number to ensure proper fuel delivery, accurate injection timing, and long-term reliability of the diesel fuel injection system.
