FAQ

Q: How can I confirm this nozzle fits my Yanmar 4TNE92 engine?
A: Please check the number stamped on your old nozzle. If it matches any of the following numbers—DN0PDN158, 105007-1580, or 119717-53010—this is the correct part. If you have a different number, please contact us with your engine serial number for cross-verification.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. Ensure the injector body seat is clean and free of debris. Lubricate the nozzle threads lightly with diesel fuel and tighten to the manufacturer’s specified torque setting (typically 50-70 Nm for these nozzles). Do not overtighten, as this can distort the nozzle body. Always replace the copper sealing washer.

Q: How do I maintain these injector nozzles for longer life?
A: The lifespan of an injector nozzle is heavily dependent on fuel quality. Use clean, high-quality diesel fuel and replace your fuel filters at the recommended intervals. If you notice symptoms like hard starting, excessive smoke, or engine misfiring, inspect the nozzles promptly. We recommend replacing nozzles in sets (all 4 for a 4-cylinder engine) to ensure balanced fuel delivery across all cylinders.
