FAQ

Q: Will this nozzle fit my engine if I have a different OEM number like 093400-0860?
A: No. The 093400-0870 (DLLA155S713) is a specific nozzle. The 0860 model often has a different spray angle or flow rate. Always match the exact part number stamped on your old nozzle. Using the wrong nozzle can cause poor performance or engine damage.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. Ensure the injector body is clean and the seating surface is free of carbon. Torque the retaining nut to the manufacturer’s specifications (typically 25-35 Nm). It is critical to replace the copper washer (heat shield) at the same time to prevent blow-by.

Q: How should I store these nozzles before installation?
A: Store the nozzles in a clean, dry environment. Do not remove the protective caps until immediately before installation to prevent contamination of the precision-machined orifice. Exposure to dust or moisture can cause the needle valve to stick.
