FAQ

Q1: How do I verify that this 7183-113L rotor is the correct part for my CAV DPA pump?
A: First, visually check the existing rotor in your pump. The part number (7183-113L) and the rotor number (436L) should be stamped or laser-etched on the component. Critically, confirm the specification “4/7R” is correct for your application. The “4” indicates it is for a 4-cylinder pump, and “7R” indicates the rotor diameter and type. If these numbers match your current part, it is a direct replacement.

Q2: What are the common signs of a failing DPA head rotor that would require replacement?
A: A worn or damaged head rotor typically causes hard starting, unstable idling, reduced engine power, black smoke from the exhaust, and fuel starvation under load. You may also notice fuel leakage from the pump body. If you experience these symptoms and have ruled out other fuel system issues (like clogged filters or air in the lines), the head rotor is a likely culprit.

Q3: Can this rotor be installed by a general mechanic, or does it require a specialist?
A: Replacing the head rotor is an intermediate-level repair. It requires disassembly of the DPA pump, which involves precise timing marks and cleanliness. While a skilled diesel mechanic with the correct service manual can perform the replacement, we recommend it be done by a specialist fuel injection service center. They will have the necessary tools (e.g., a pump test bench) to calibrate the pump after assembly to ensure optimal performance and timing.
