7123-304T Diesel Injection Pump Head Rotor for Lucas CAV DPA Systems

The 7123-304T Diesel Injection Pump Head Rotor is the hydraulic heart of the distributor-type fuel injection pump. Designed specifically for Lucas CAV DPA series rotary pumps, this component is responsible for distributing high-pressure fuel to the engine cylinders in the exact firing sequence.

Manufactured from premium bearing-grade steel, the 7123-304T undergoes rigorous heat treatment and precision grinding processes. This ensures an extremely tight clearance fit between the rotor and the hydraulic head, which is essential for maintaining high injection pressure and preventing internal fuel leakage.

This head rotor is widely compatible with various agricultural and industrial diesel engines (such as Perkins, Massey Ferguson, and Ford) that utilize the DPA injection system. Replacing a worn or seized head rotor with the 7123-304T effectively resolves issues such as hard starting when hot, uneven engine idling, and loss of power, restoring the pump to its original factory specifications.

• OEM Precision: Manufactured to exact factory tolerances to ensure perfect hydraulic sealing and fuel metering accuracy.

• Wear Resistance: Constructed from high-hardness alloy steel to withstand the friction of constant rotation and high fuel pressure.

• Enhanced Performance: Resolves common "hot start" failure issues caused by wear in the original hydraulic head.

• Wide Application: Compatible with a broad range of classic diesel engines using the DPA rotary pump system.

• Cost-Effective Repair: Provides a high-quality solution for pump rebuilding without the need to replace the entire injection pump assembly.
