Frequently Asked Questions
Which engines can the 4W-7020 pencil injector fit?
4W-7020 pencil injector is compatible with Caterpillar 3400-series engines including 3408, 3408B, 3412 and 3412C. It applies to heavy-duty bulldozers and generator set equipment. Its cross-reference part number is 0R-8791 for alternative selection.
Can I change only the nozzle instead of whole 4W-7020 injector assembly?
Not advised. The nozzle is integrated inside the 4W-7020 injector body. Field repair usually replaces the full injector assembly. Separate nozzle replacement may cause poor atomization, fuel leakage and unstable engine performance.
What plunger and fuel pump match 4W-7020 injector?
The supporting inline mechanical fuel pump part number is 7N1220, and the matching pump plunger element number is 7W-0182. The pump provides high-pressure fuel supply, while the 4W-7020 injector controls fuel spray and atomization independently.
