Caterpillar original  20R-8056 Fuel Injector Nozzle for C7 Diesel Engine Excavator Construction Machinery Replacement for OEM new injector original new injector

Engineered as a direct original-type replacement for the . C7 platform, this HEUI diesel fuel injector carries the primary OE reference 20R-8056 and cross-references 10R-4762, 10R-7225, 20R-1260, 20R-8057, 20R-8058, 20R-8059, 387-9430, 387-9429, 387-9428, 295-1408, 295-1409, and 295-1410. It is purpose-built for C7, C7 ACERT, and C7.2 engines rated 225–300 bhp / 168–224 bkW at 1800–2200 rpm, operating in the inline 6-cylinder, turbocharged and air-to-air aftercooled configuration with firing order 1-5-3-6-2-4.

The injector integrates with ECM-controlled Hydraulic Electronic Unit Injector architecture, delivering precision fuel metering, high-pressure oil actuation, and stable atomization across the full load range. A heavy-duty body construction supports demanding duty cycles in excavators, wheel loaders, track loaders, motor graders, vocational trucks, buses, coaches, generator sets, marine auxiliary units, and agricultural or irrigation power packs. Correct spray geometry helps restore rated engine power, support fuel economy, promote cleaner combustion, improve cylinder balance, and reduce repair downtime for fleet operators and rebuilders.

Each unit is packaged in sealed protective materials to guard against dust, moisture, and impact during transit and storage. Recommended service practice includes clean diesel fuel, correct oil grade for HEUI actuation, timely filter replacement, water separator draining, and ECM fault-code scanning. HEUI injectors are not internally serviceable, making this replacement ideal for workshops, parts distributors, and OEM-level engine rebuild programs.
