FAQ

1. How do I verify if this 7185-101L rotor head fits my pump?

Please check the model number on your current fuel injection pump. This rotor head is specifically designed for DP200 series pumps and replaces the OEM number 7185-101L. It is crucial to visually compare the part with your existing rotor head and confirm the pump model. If you are unsure, please provide the pump model and serial number to our sales team for verification.

2. What are the common signs of a failing fuel pump rotor head?

Common symptoms include: engine hard starting or failing to start, irregular idling or surging, loss of engine power under load, black smoke from the exhaust due to incomplete combustion, and internal fuel leakage. Replacing a worn rotor head can resolve these issues and restore pump performance.

3. What is the recommended maintenance or installation procedure for this part?

Installation should be performed by a qualified diesel technician. The work area must be extremely clean to prevent contamination. It is recommended to replace the rotor head along with other wear items like the delivery valves and seals. After installation, the fuel injection pump must be correctly timed and bench-calibrated to ensure proper fuel delivery and engine operation. Always consult the pump’s service manual for specific torque settings and procedures.
