FAQ

Q1: What is the function of the head rotor in the injection pump, and how do I know if mine is failing?
A: The head rotor is the central rotating component that distributes high-pressure fuel to each injector line in the correct firing order. Common signs of a failing head rotor include hard starting, engine misfiring, rough idling, a significant loss of power, and black smoke from the exhaust due to incomplete combustion. If you experience these issues, inspecting the injection pump head rotor is a critical step.

Q2: Is this head rotor a direct bolt-on replacement for my 4BE1 engine pump?
A: Yes, this part (146402-1420 / 9 461 613 791) is specifically manufactured as a direct replacement for the 4BE1 engine’s fuel injection pump. However, installation of a head rotor is a precision task that requires experience with diesel fuel injection systems. It involves careful disassembly, cleaning, and precise reassembly to ensure correct timing and sealing. We highly recommend installation by a qualified diesel mechanic.

Q3: What is your MOQ and typical lead time for international orders?
A: The minimum order quantity (MOQ) is 6 pieces. For stock items, orders are typically dispatched within 3-7 business days after payment confirmation.
