FAQ

Q: Is this part a direct replacement for my existing DP200 pump head rotor?
A: Yes, this part (7189-187L) is a direct replacement for the original head rotor in DP200 series fuel injection pumps. It is designed as a drop-in fit. We always recommend comparing your old part’s number with the OEM number (7189-187L) and rotor number (943L) to confirm compatibility.

Q: What is the recommended installation procedure for this head rotor?
A: Installation should be performed by a qualified diesel mechanic. The process involves carefully disassembling the fuel injection pump, cleaning all components, and replacing the old head rotor with the new one. It is critical to lubricate the part with clean diesel fuel during installation and to follow the pump manufacturer’s torque specifications and timing marks.

Q: How can I ensure the longevity of this fuel injection pump component?
A: Longevity is maximized by using clean, high-quality diesel fuel, regularly changing fuel filters, and ensuring the fuel system is free from water and contaminants. Adhering to the engine’s scheduled maintenance intervals will also help prevent premature wear of the head rotor and other pump internals.
