Description
319‑0677 (3190677) fuel injection pump serves as the core fuel delivery component for Caterpillar C7 engine powered equipment. It precisely pressurizes and delivers fuel to each cylinder, ensures accurate fuel supply timing, stabilizes engine combustion process, maintains consistent power output, and optimizes fuel consumption for excavators and wheel loaders working under heavy‑load site conditions.
Compatible Models
Fits machines equipped with CAT C7 engine:
Excavator: 324D, 325D, 329D, 330D, 336D
Wheel Loader: 950H, 962H
Key Features & Benefits
Precise fuel delivery performance: Strict manufacturing tolerances guarantee stable fuel pressure and accurate injection timing. Delivers even fuel supply for every cylinder, supports reliable engine ignition, reduces rough idling, power drop and black exhaust smoke caused by unstable fuel supply.
Heavy‑duty structural design: Built to withstand frequent load changes, vibration and temperature fluctuation on construction sites. High wear‑resistant internal components keep steady working performance under long‑time continuous operation.
Strict dimensional consistency: Matches installation dimension requirements of part number 319‑0677. Direct fit during assembly without extra modification. Simplifies on‑site replacement work for equipment maintenance.
Improve engine working efficiency: Optimized internal flow structure helps achieve full fuel combustion. Helps lower excessive fuel burn, reduces exhaust emission, restores original machine power and response performance.
Reduce equipment downtime: Reliable fuel pump performance avoids common failures such as hard starting, engine stalling and power shortage. Great for repair shops, equipment fleets and individual owners to complete engine overhaul and routine maintenance.
