FAQ

Q: Is this rotor head a direct replacement for my DPS pump?
A: Yes, this part (7183-125L / 528L) is designed as a direct replacement for DPS pump heads. However, we recommend comparing the part number and physical dimensions (7mm diameter) with your existing rotor to confirm fitment for your specific engine model.

Q: What is the installation procedure for this part?
A: Installation should be performed by a qualified diesel mechanic. It involves disassembling the injection pump, removing the old rotor head, and installing the new one with proper torque specifications. Ensure the pump housing is clean to avoid contamination. Professional service is recommended.

Q: How do I maintain the rotor head for long service life?
A: Use clean, high-quality diesel fuel and replace fuel filters regularly. Ensure the injection pump is properly timed and lubricated. Avoid running the engine with contaminated fuel, as this can cause premature wear to the rotor head and other pump components.
