10R-3266 Ca-terpillar C15/C27 Reman Fuel Injector (EUI) – Replaces 253-0617

10R-3266 Ca-terpillar C15/C27 Reman Fuel Injector (EUI) – Replaces 253-0617

This electronic unit injector (EUI) is a direct, OEM-equivalent replacement for Ca-terpillar C15, C16, C18 and C15 ACERT diesel engines. Cross-referenced against OEM part numbers 253-0615, 253-0616, 253-0617 and remanufactured numbers 10R-3264, 10R-3265, 10R-3266 (plus 10R-1273, 10R-9236 for the C15 ACERT group), it is a true bolt-on fit with no core required.

Each unit is flow-matched and 100% bench-tested for injection pressure, spray pattern and delivery volume — delivering consistent firing, faster cold starts, better fuel economy and lower smoke across the full load range. The hard-coated plunger resists wear from today's low-sulfur diesel, extending service life between overhauls.

Proven across the toughest applications: 365C/374D-class excavators, 834H wheel dozers, 990H wheel loaders, D10N/D10R/D10T dozers and AD30/AD55B haul trucks. Always verify fitment by engine serial number (ESN) before ordering.
