FAQ

Q: How do I confirm this head rotor (7189-947K) fits my injection pump?
A: Verify your pump’s rotor number. This part is specifically listed as Rotor No. 004K 4/7L. Cross-reference your existing part number with 7189-947K or OEM 7189947K. Measure the rotor dimensions if possible to ensure compatibility with your pump model.

Q: What is the recommended installation procedure for this head rotor?
A: Installation should be performed by a qualified diesel technician. Ensure the pump housing and all mating surfaces are perfectly clean. Lubricate the rotor with clean diesel fuel or assembly oil before installation. Torque all retaining components to manufacturer specifications and re-calibrate the pump on a test bench for optimal performance.

Q: What maintenance is required for this fuel injection pump head rotor?
