Frequently Asked Questions
What engines does the Yanmar 129004-18010 injector fit?
The 129004-18010 is a fuel injector nozzle designed for Yanmar TNV series engines, primarily the 3TNV88 and 4TNV98. It may also fit other TNV variants — confirm your engine serial number before ordering.
How do I know if my injector needs replacing?
Symptoms include hard starting, rough idling, black or white exhaust smoke, reduced power, increased fuel consumption, and fuel knock. A professional injector test bench can confirm spray pattern and opening pressure.
Should I replace all injectors at once?
Yes — it is strongly recommended to replace all injectors as a set. Mixing old and new injectors leads to uneven fuel delivery, cylinder imbalance, and poor engine performance. Always replace the entire set.
Do you supply genuine Yanmar or aftermarket injectors?
We supply both genuine Yanmar OEM 129004-18010 injectors and high-quality aftermarket alternatives from trusted manufacturers. Genuine is recommended for newer engines under warranty; aftermarket is cost-effective for older models.
Can you ship the 129004-18010 to Sabah or Sarawak?
Yes. We ship to all Malaysian states including Sabah and Sarawak. East Malaysia deliveries typically take 3–5 working days. We also arrange air freight for urgent orders.
