FAQ

Q: How do I know if this orifice plate (G4/G10) is the correct replacement for my injector?
A: Please check the part number stamped on your existing injector or valve plate. This item is a direct replacement for parts with the numbers S55013h50, S56013h50, S560-13h50, and S550-13h50. It corresponds to the G4, G04, and G10 control valve specifications. If you are unsure, please contact our 24-hour customer service with your injector’s model number.

Q: What is the function of this orifice plate, and why is it important?
A: The orifice plate is a precision component inside the injector control valve. It meters the flow of fuel, creating the precise pressure needed for injection. A worn or damaged plate can cause poor engine performance, rough idling, increased fuel consumption, and black smoke. Replacing it restores the injector’s hydraulic balance.

Q: Can I install this part myself, or does it require special tools?
A: Replacing the orifice plate is a delicate task that is part of a full injector rebuild. It requires a clean, dust-free environment and specialized tools for disassembly and reassembly to avoid damaging the new plate. We strongly recommend installation by a qualified diesel injection technician to ensure proper torque and cleanliness.
