Frequently Asked Questions
1. What engine does 4P9830 fit?
The 4P9830 plunger & barrel assembly is designed for Cater-pillar 3306, 3306B, and 3306C diesel engines.
It also fits Cat construction/industrial equipment such as the 330, 330B, 330C excavators, 814B/814F wheel dozers, 12H/14H motor graders, and 572R pipelayers.
It serves as a direct replacement for fuel injection pumps in these engines, ensuring precise fuel metering and stable high-pressure delivery.
2. Is 4P9830 compatible with CAT 3412?
No, the 4P9830 is not compatible with the CAT 3412 engine. The 3412 requires a different plunger model, such as the 1086631 (or 2W3414), which is specifically engineered for the 3412, 3406B, and 3406C engines. Using 4P9830 in a 3412 will result in improper fit, fuel pressure issues, and potential engine damage.
3.Does 4P9830 reduce smoke?
Yes, installing a new, high-quality 4P9830 plunger and barrel assembly can effectively reduce black or white smoke from the engine.
This part controls fuel pressure and injection volume. A worn plunger causes poor fuel atomization, incomplete combustion, and excessive smoke. By restoring precise fuel metering and stable high-pressure delivery, the 4P9830 improves combustion efficiency, lowers exhaust smoke, and helps restore normal engine performance.
