FAQ

Q1: How do I confirm this valve plate 517# is the correct part for my injector?
A: First, verify your injector’s part number (e.g., 095000-1440). This plate is an internal component for those specific injectors. If you are rebuilding an injector, you should visually compare the old plate to the new one. The diameter and hole pattern must match exactly. When in doubt, contact us with your injector model and number for confirmation.

Q2: What is the installation procedure for this valve plate?
A: Installation requires precision and a clean environment. The plate is typically positioned inside the injector body, held in place by the nozzle or control valve assembly. It must be installed with the correct orientation. We recommend installation by a qualified diesel technician using proper torque specifications and tools to avoid damage to the delicate surfaces.

Q3: What maintenance is required for this part?
A: This valve plate is a wear item within the injector. There is no routine maintenance for the part itself. However, to maximize its lifespan, ensure the fuel system is clean and free of contaminants. Always use high-quality diesel fuel and replace fuel filters according to the vehicle manufacturer’s schedule. If injector performance degrades, this plate should be inspected along with other internal components.
