FAQ

Q1: Is this injector a direct replacement for the original Weichai 13074417 part?
A: Yes, this injector (0445120459) is a 100% direct replacement for the OEM Weichai part number 13074417. It matches the original specifications, connector type, and mounting dimensions for a plug-and-play installation.

Q2: What is the recommended installation procedure for this common rail injector?
A: Installation should be performed by a qualified diesel technician. Key steps include: 1) Cleaning the injector bore in the cylinder head. 2) Replacing the copper washer and O-rings. 3) Tightening the injector clamp to the manufacturer’s specified torque (typically 35-45 Nm). 4) Ensuring the high-pressure fuel line connections are clean and tight. It is highly recommended to replace the fuel filter after installation.

Q3: How should I store this injector before installation?
A: Store the injector in its original packaging in a clean, dry environment away from dust and moisture. Avoid removing the protective caps from the fuel inlet and nozzle tip until just before installation to prevent contamination, which is a leading cause of injector failure.
