4P9827 Fuel Injection Pump Plunger Assembly for 3306 3306B Diesel Engine E325B E330 Excavator Parts

The 4P9827 Fuel Injection Pump Plunger Assembly is a replacement diesel fuel injection pump component offered for compatible 3306 and 3306B diesel engine applications, including selected E325B and E330 excavator configurations.

As an important component of a mechanical diesel fuel injection pump system, the plunger assembly helps generate and regulate fuel pressure through precise mechanical movement within the corresponding pump mechanism.

A correctly matched and functioning fuel pump plunger assembly helps support controlled fuel delivery, stable engine operation, and the designed performance of the diesel fuel injection system.

The 4P9827 assembly features a precision-machined metal body, spring-loaded mechanism, threaded connection end, cylindrical shaft, and gear-shaped drive end.

Designed for diesel engine fuel system maintenance and injection pump repair, this component provides a replacement option for worn, damaged, or malfunctioning fuel pump plunger assemblies.

JISION supplies diesel fuel injection pump components, engine replacement parts, and construction machinery spare parts for excavator owners, diesel engine repair workshops, and international spare parts distributors.
