Caterpillar original Replacement Fuel Injector 10R-1288 for Caterpillar 3508 3512 3516 Engines, Cross Reference 386-1758, 392-0206, 20R-1270, for PM3508B PM3516B Machinery original new injector

The Genuine CAT 10R-1288 is an industrial-grade high-pressure direct injection diesel fuel injector engineered as a direct replacement for heavy-duty Caterpillar 3500 Series engines, covering 3508B, 3508C, 3512B, 3512C and 3516B models. Designed to deliver diesel fuel directly into the combustion chamber at 1600–2000 bar operating pressure, it ensures precise fuel metering, optimal atomization and uniform combustion, boosting power output, reducing fuel consumption, cutting harmful emissions, and extending engine service life for demanding working conditions.

This injector supports OEM replacement, aftermarket cross-reference and remanufacturing program needs, with verified reman part numbers 0R8685, 0R9348 and cross-reference codes 126-2081, 127-8216, 392-0201 (plus non-hyphenated variants). It fits a wide range of heavy-duty industrial equipment across core sectors: CAT 3512B generator sets, commercial offshore marine vessels, mining haul trucks and excavators, construction earthmoving machinery, oil and gas drilling and compression equipment, and stationary industrial power facilities.

Built to strict CAT OEM calibration and alignment standards, the 10R-1288 uses a direct-fit design with 40–45 Nm installation torque, requiring pre-installation fuel system cleaning and OEM-recommended fuel rails for reliable performance. Scheduled maintenance follows official CAT specifications: 250-hour fuel filter replacement, 1000-hour injector inspection, regular leak checks and fuel analysis, with performance testing aligned to major overhauls to minimize unplanned industrial downtime.
