Caterpillar original Fuel Injector 20R-1260 241-3238 387-9426 20R-8071 384-9426 C7 C9 324D 325D 329D 336D 584 545C Replacement OEM original new injector

Engineered for demanding off-highway service, this C7 Series diesel fuel injector carries primary OE identification 20R-1260 and is fully cross-referenced with 387-9426 and 20R-8071, along with 328-2586, 295-1412, 268-1836 and 241-3238. Both hyphenated and supplier-indexed forms such as CA3879426, CA20R1260 and CA20R8071 are covered, giving procurement teams and reman exchange programs wide OE coverage and reliable part identification across global aftermarket catalogs.

Designed specifically for C7 diesel engines, the injector is a proven fit for 324D, 325D, 329D, 330D and 336D excavators, E324D / E325D / E329D machines, 545C wheel skidders and 584 / 584HD forwarders, as well as C7-based industrial power units and generator sets. Heavy-duty construction, precision fuel metering, correct atomization and stable injection timing support combustion efficiency, controlled emissions and long service life under continuous load in construction, forestry, mining, agricultural and marine auxiliary applications.

Each unit is functionally tested to verify response, flow and return characteristics before shipment. For best results, confirm the old injector number and engine serial number, replace O-rings, apply correct torque, program trim codes where required, and prime the fuel system. Recommended diagnostics include fault-code scanning, injector balance and cylinder cut-out testing, return-flow measurement and harness inspection to isolate misfire, hard starting, smoke or power-loss symptoms.
