Construction machinery For 319-0677 3190677 Diesel Pump CAT C7 C9 Excavator engine parts

Specification

Description

This diesel fuel pump with part number 319-0677 (3190677) is specially designed for C7 and C9 series engines of construction machinery, widely applied to excavators and other engineering equipment. Manufactured with original-standard craftsmanship, the pump is matched with the HEUI hydraulic electronic fuel injection system. The complete set includes the main fuel pump body, professional installation manual and independent outer packing box, together with factory warning labels for assembly guidance. The precisely machined gear structure supports direct replacement installation for the engine fuel supply system, perfectly fitting the mounting position of corresponding machinery to meet the fuel delivery demand of construction equipment.

Advantage

Adopts precision gear transmission with factory clearance calibration, featuring stable transmission and accurate positioning, which supports direct installation without secondary modification.
Optimized for the mature HEUI fuel injection system, equipped with a professional system diagnostic manual to simplify equipment installation, commissioning and troubleshooting, effectively reducing maintenance difficulty.
The pump housing is made of high-strength alloy material, with excellent vibration resistance and wide temperature adaptability, capable of stable operation in harsh working environments such as construction sites and mines, avoiding oil leakage and shell deformation during long-term service.
Each pump undergoes strict tests on pressure tightness and fuel supply stability before delivery. Independent packaging effectively prevents collision damage during transportation and guarantees reliable installation performance.
Standard dimensional parameters ensure perfect replacement of the original damaged fuel pump, restoring the rated power output of the engine and solving common failures including weak power, difficult startup and abnormal fuel consumption.

Performance

Stable high-pressure fuel supply ensures even fuel injection for each cylinder of the engine, enabling fast startup, smooth idle speed and eliminating abnormal shaking or sudden flameout.
Dynamic pressure adjustment automatically matches different engine load conditions. It delivers sufficient power under heavy load and optimizes fuel consumption under light working conditions to improve fuel economy of construction machinery.
Multi-channel sealing structure provides outstanding high temperature and high pressure resistance, effectively preventing oil seepage and leakage at oil ports and gear mounting positions during long-time continuous operation.
Standard electronic control interface realizes stable signal interaction with the original engine ECU system, avoiding false fault codes and wrong fuel injection timing.
The surface-hardened transmission gear features high wear resistance and fatigue strength, adapting to frequent start-stop and high-intensity working conditions to greatly extend the service life of the fuel pump.
