FAQ

Q1: What is the function of this G4 orifice plate in the injector?
A: The orifice plate is a critical component of the injector’s control valve. It precisely regulates the flow of fuel into the control chamber. A worn or damaged orifice plate can cause starting issues, rough idling, poor fuel economy, and reduced engine power. Replacing this plate during an injector rebuild restores the control valve’s ability to manage injection timing and fuel quantity accurately.

Q2: How do I know if this orifice plate (295040-9440) is the correct part for my injector?
A: This part is commonly used in specific Toyota and Hyundai diesel injectors. To confirm compatibility, you should first check the part number stamped on your injector body. If the injector number is 295040-9440, or if the internal control valve assembly uses an OEM “G4” plate, this is the correct replacement. We recommend consulting your injector’s service manual to verify the internal parts.

Q3: What is the recommended installation procedure for this part?
A: Installation requires precision and a clean environment. The new orifice plate should be handled with clean, lint-free gloves. Ensure the mating surfaces inside the injector body are perfectly clean and free of debris. The plate must be positioned correctly within the control valve assembly, often requiring a specific orientation. It is highly recommended that this replacement be performed by a qualified diesel technician using the proper tools and torque specifications to avoid damage to the new part or the injector.
