FAQ

Q1: How do I confirm this head rotor fits my injection pump?
A: Check the tag on your pump for the plunger size. This rotor is a “4/10 R” type, meaning it is for a 4-cylinder pump with a 10mm plunger diameter. The primary reference number on your pump should match 146400-2220 or 9461610167. If you have a different number, please contact us with a photo of your pump’s data plate.

Q2: What is included in the package?
A: The package includes one (1) new head rotor assembly. For a complete pump overhaul, you may also need a delivery valve holder, gasket kit, and timing shims, which are sold separately. Please ensure you have a proper seal kit for reassembly.

Q3: What maintenance is required after installation?
A: After installing the new head rotor, the injection pump must be re-timed and calibrated on a test bench by a qualified diesel technician. Ensure the fuel is clean and free of water to prevent premature wear. We recommend checking the pump timing after the first 50 hours of operation.
