FAQ

Q1: How do I confirm this valve plate fits my injector?
A: Please check the OEM number stamped on your existing injector valve plate. This part is a direct replacement for numbers 1465A439, 295050-1760, and 166005X30A. If your part is marked as a “509#” plate, it is likely compatible. If unsure, please contact us with your injector’s brand and model number for verification.

Q2: Is professional installation required for this part?
A: Yes. Replacing the valve plate inside a common rail injector is a precision task that should be performed by a qualified diesel technician. The injector must be disassembled, cleaned, and reassembled with proper torque specifications to avoid fuel system damage. We recommend using a specialized injector service tool for installation.

Q3: What is the expected lifespan of this valve plate?
A: The lifespan depends on fuel quality and operating conditions. Under normal conditions with clean diesel fuel, this high-speed steel plate can provide long-lasting service. However, contaminated fuel can cause premature wear. Regular injector maintenance is recommended to maximize the lifespan of all internal components, including the valve plate.
