Fuel pump flange connection plate 5I-7576 for Caterpillar CAT 3064, 3066 engines and 311, 312, 314C, 318C, 319C, 320B, 320C, 320D, 320N, 321C type excavators.

Product Overview

Core Functions

1. Precise Positioning & Sealing: Provides accurate mechanical mounting positioning for the fuel transfer pump, ensuring perfect alignment between the pump body and the engine drive shaft; meanwhile, it isolates high-pressure fuel through the precision-machined sealing surface, preventing fuel leakage and air mixing, avoiding engine power loss and potential safety hazards.
2. Vibration Buffering & Structural Support: Made of high-strength aluminum alloy, it combines rigidity and shock absorption, effectively buffering high-frequency vibration during engine operation, protecting the fuel pump drive shaft and seals, extending fuel pump service life and reducing system failures.
3. Fuel System Stability Guarantee: Maintains the coaxiality and sealing of the fuel pump installation, ensuring stable fuel supply pressure, avoiding pump wear and insufficient fuel supply caused by installation deviation, ensuring reliable engine start and stable operation under all working conditions.
4. Ready-to-Install: 1:1 reproduction of the original factory size, mounting hole position and sealing groove structure, fully matching the fuel pump mounting position of Caterpillar 3064/3066 engines and corresponding excavators. No modification required, direct replacement of the original part, convenient and efficient maintenance, greatly reducing downtime.
