Cat Diesel Fuel Rebuilt Injectors 350-7555 Wear Resistance For C-10 C-12 Engines

The 350-7555 is a diesel electronically controlled unit fuel injector designed for Cat heavy-duty construction machinery and industrial engines. It is commonly interchangeable with the remanufactured part number 20R-0056.

• High-Precision Control: The injector delivers diesel fuel into the cylinder at precisely timed intervals, under extremely high pressure, and with optimal atomization — ensuring combustion efficiency, power output, and emissions compliance.
• Wear-Resistant Design: Internally equipped with specially coated plungers that provide superior wear resistance, enabling reliable performance with low-sulfur and low-lubricity diesel fuels while extending service life.

This injector is designed for use with several classic high-horsepower Cat engine platforms, primarily the CAT C-10 and CAT C-12 engines. It is widely installed across the following heavy equipment categories:

• CAT 345B, 345B II, 365B, 365B L series

• CAT 16H

• CAT 725, 730

• CAT 972G II

• CAT MT835, MT845, MT855, MT865 series
