FAQ

Q1: Is this head rotor a direct replacement for my CAV DPA pump?
A: Yes, the 7180-578M is an OEM number for a standard CAV DPA head rotor. It is a direct replacement designed to fit pumps with a 4/7.5L displacement rating. Please verify your pump’s model and existing part number to ensure compatibility.

Q2: What are the key signs that my head rotor needs replacement?
A: Common symptoms include hard starting, engine misfiring, loss of power, black smoke from the exhaust, or fuel leakage from the pump. A worn head rotor can cause inconsistent fuel pressure and timing, leading to poor engine performance.

Q3: Do I need any special tools to install this part?
A: Installation of a head rotor is a complex task that requires disassembling the injection pump. It is highly recommended that this job be performed by a qualified diesel technician using specialized tools to ensure proper timing and calibration. Incorrect installation can damage the pump or engine.
