Caterpillar original 7E-7607 Diesel Fuel Injector Nozzle Replacement for OEM 3116 3114 E322B E322C E325B Excavator, Replaces 107-7734 7E-8952 original new injector

The 7E-7607 unit injector is engineered as an OE-style replacement solution for the CAT 3116 diesel engine platform, including 3116B and 3116C variants with 7.2L displacement. Built to deliver precision fuel metering under continuous heavy-duty operation, this injector supports stable combustion, smoother engine running, improved fuel efficiency, and reduced exhaust smoke in demanding environments. Extensive cross-reference coverage—including 7E-8952, 0R-3389, 0R-4374, 0R-8471, 127-8220, 127-8222, 107-7734, and 4P-2995—allows global distributors, repair shops, reman programs, and fleet maintenance operations to consolidate inventory across multiple CAT 3116 applications.

Designed for use in wheel loaders such as the CAT 950F, excavators, backhoe loaders, industrial generator sets, heavy trucks, mining equipment, agricultural equipment, marine auxiliary power units, and general construction machinery, the 7E-7607 withstands vibration, temperature variation, and prolonged duty cycles. To preserve performance and service life, operators should use clean diesel with high-quality filtration, replace fuel filters on schedule, drain the water separator regularly, and conduct injector testing when symptoms such as hard starting, black smoke, rough idle, misfire, knocking, or elevated fuel consumption appear.

Available in new aftermarket, replacement, remanufactured, rebuildable core, and OEM-type replacement conditions, the 7E-7607 provides flexible supply options for B2B procurement. Each unit is packaged in sealed, anti-rust, moisture- and impact-resistant material to ensure integrity during storage and global shipping, supporting distributors and service networks serving CAT 3116-powered fleets worldwide.
