Product Overview
Cross-reference application data shows this injector used much more broadly than the original 120H/446B/446D title. Documented 3114/3116 applications include 320B/322B/322C/325B excavators, 120H/135H graders, 953C/963B/963C track loaders, D5M/D6M tractors, several wheel loaders and integrated toolcarriers.
The injector meters fuel into each cylinder under high pressure. Poor spray pattern or leakage can cause hard starting, smoke, rough running and reduced power, but injection timing, compression and pump condition should also be considered when diagnosing a 3114/3116 engine.

Frequently Asked Questions
Is this injector only for a CAT 120H?
No. The same cross-reference appears across many 3114/3116-powered Caterpillar machines.
Should one injector be replaced or the whole set?
That depends on test results and engine condition. Individual injectors can be replaced, but a diesel shop may recommend testing all injectors when symptoms affect multiple cylinders.
