original C7 Engine Injector 295-1408 20R8057 10R4761 2413238 Replacement for OEM Excavator Spare Part new injector original new injector

The C7 HEUI diesel fuel injector 295-1408 is engineered as a direct engine-specific replacement for the C7 diesel platform, delivering matched fitment with the HEUI-type fuel injection system used across the inline six-cylinder configuration. Built with a heavy-duty structure and precision-machined internal components, this injector supports accurate fuel atomization and consistent injection pressure required by the C7 engine architecture. The part is cross-referenced with 20R-8057, 10R-4761, CA2951408, 295-1410, 241-3400, 387-9428, 222-5961, 233-3536, 236-0973, 241-3238, 243-4502, and 328-2583, allowing repair teams and distributors to consolidate sourcing through a single C7 injector line.
Designed for global aftermarket and industrial engine rebuild supply, this C7 injector is suitable for excavators such as the 324D, 325D, and 328D, the 120K2 motor grader, generator sets, pump units, mining equipment, road construction machinery, agricultural machinery service, marine auxiliary equipment, and broader commercial diesel applications. Each unit is supplied in sealed packaging to maintain cleanliness during storage and export logistics, supporting part-number-based sourcing, fast cross-reference identification, and six-cylinder set replacement options when injector balance is poor across the engine.
Correct HEUI operation depends on clean diesel fuel, proper fuel pressure, and correct engine oil pressure for actuation. Before replacement, technicians should perform diagnostic scanning, fuel pressure testing, oil pressure testing, cylinder cut-out testing, injector leakage testing, and fuel quality inspection to confirm root cause. Common symptoms such as hard starting, rough idle, black or white smoke, misfire, power loss, high fuel consumption, knocking noise, high exhaust temperature, fuel in oil, diagnostic trouble codes, and uneven cylinder temperature often indicate injector-related faults including poor atomization, injector leakage, wiring problems, fuel contamination, low fuel pressure, incorrect oil pressure, or cylinder imbalance. A full set replacement is recommended when cylinder contribution is uneven.
