Caterpillar original 10R-4761 Fuel Injector Nozzle for C7 C9 Excavator Engine, Replacement for OEM Diesel Pump Injector 20R-1260 328-2586 original new injector

Engineered for demanding fuel delivery duty cycles, the 10R-4761 Common Rail Fuel Injector is a precision electronic unit injector designed to restore factory-grade combustion performance on C7, C7 ACERT, and C7.1 diesel engines. Fully cross-referenced with 236-3273, 317-4891, 236-3267, 236-3269, and 236-3275, this brand-new assembly is a direct-fit replacement for excavators including 320D, 321D, 323D, 324D, 325D, 329D, 330D, and 336D, as well as industrial generator sets, marine propulsion units, and stationary power stations.

Manufactured from high-strength alloy steel with precision-ground valve assemblies and hardened nozzle technology, the 10R-4761 delivers exact spray geometry, atomization, and injection timing. Every unit undergoes 100% fuel flow testing, leakage testing, spray pattern verification, response testing, and calibration to guarantee consistent performance across the operating range. Field benefits include improved fuel economy, reduced black smoke, enhanced engine power, faster throttle response, stable idle, lower emissions, longer service life, and reduced maintenance cost.

For optimal reliability, replace injector seals during installation, clean the injector bore, verify ECM calibration, apply the recommended torque values, and complete injector coding where required. Use ultra-clean diesel, replace fuel filters on schedule, avoid water contamination, and maintain proper rail pressure. Supplied in export-standard packaging with a 12-month warranty, this injector is ideal for construction, mining, oilfield, agricultural, and fleet applications worldwide.
