FAQ

Q: What are the signs that my head rotor needs replacing?
A: Common symptoms include difficulty starting the engine, uneven engine running (misfiring), black smoke from the exhaust due to incomplete combustion, and a noticeable loss of power under load. These issues often stem from wear on the rotor’s precision surfaces.

Q: Is this a direct replacement for my Nissan TD27 injection pump?
A: This head rotor is designed for the injection pump used on the Nissan TD27 and AD23 engines. However, there are different pump variants (e.g., Bosch VE, Zexel). We recommend checking your pump’s model number and comparing it with the part numbers (146401-0520 or 9 461 612 068) to ensure a perfect fit.

Q: What is the recommended installation procedure?
A: Installation of a head rotor requires specialized knowledge and tools. It is a critical internal component of the injection pump. We strongly advise that this replacement be carried out by a qualified diesel injection technician on a calibrated test bench to ensure proper timing and pressure settings after installation.
