Frequently Asked Questions
What engine does the 4W‑7019 unit injector fit for?
The 4W‑7019 unit injector is designed for Caterpillar 3400‑series engines, including 3408, 3408B, 3408C, 3412, 3412B and 3412C, widely used on heavy‑duty construction machines such as D9L, D9N, D10N bulldozers.
Can I only replace the nozzle instead of the full 4W‑7019 injector assembly?
Not recommended. 4W‑7019 is an integrated unit injector. Its nozzle is an internal built‑in component. For reliable performance in field repair, technicians usually replace the complete injector assembly rather than only the nozzle part.
What fuel pump works with 4W‑7019 injector?
The matching inline mechanical fuel pump part number 7N1220. This pump delivers high‑pressure fuel to injectors. The 4W‑7019 unit injector handles injection timing and pressure independently.
