Frequently Asked Questions
What engines and equipment does the 108-2104 plunger fit?
The 108-2104 plunger barrel assembly is designed for 3406B, 3406C, 3412, and 3412C diesel engines. It is widely applied on wheel loaders, bulldozers, motor graders, and industrial generator sets, with interchangeable OEM part number 20R-5289.
Can I replace only the plunger without the barrel assembly?
No. The plunger and barrel are precision-matched paired components. They must be replaced as a complete assembly. Separate replacement will cause fuel metering deviation, unstable injection pressure, engine power loss, and accelerated fuel pump wear.
What fuel pump and injector system matches the 108-2104?
The 108-2104 plunger matches P7100 series rotary injection fuel pumps. It works cooperatively with original 3400 series pencil fuel injectors. The plunger controls internal fuel delivery volume, while injectors complete high-pressure fuel atomization and cylinder injection.
