FAQ

Q1: What does the “6/7R” in the product title mean, and how do I know it fits my pump?

The “6/7R” designation refers to the internal geometry of the rotor, specifically the number of plungers (6) and the roller configuration (7R). This is a critical specification for the fuel injection pump. To ensure correct fitment, you must verify that your existing pump’s head rotor is marked with the same 9050-412L OEM number and has a 6/7R configuration. We recommend comparing the part visually or consulting your pump’s service manual before purchasing.

Q2: Is this a complete fuel injection pump or just the head and rotor assembly?

This product is the Head Rotor assembly only. It is the internal metering and distribution component of the fuel injection pump. It does not include the pump housing, drive shaft, or other external components. It is intended for use as a repair part to rebuild an existing pump, not as a complete pump replacement.

Q3: What is the recommended procedure for installing this head rotor?

Installation of a fuel injection pump head rotor is a precision task that requires specialized knowledge and tools. It is strongly recommended that this component be installed by a qualified diesel injection technician. The process involves disassembling the pump, cleaning all components to strict standards, carefully aligning the rotor and head, and then recalibrating the pump on a test bench to ensure correct fuel delivery and timing. Attempting installation without proper training can lead to engine damage.
