Perkins original 10R-8502 Common Rail Fuel Injector for C10 C11 C15 C16 Engine E365C E374D Excavator Replacement for OEM original new injector

The 10R-8502 electronic unit injector is engineered for Perkins C15, 3406E, and C16 heavy-duty diesel engines, covering 1995–2003 production units with common ESN prefixes 1LW, 2WS, 5EK, 6NZ, 6TS, and MBN. Built as a direct OE-style replacement, it supports heavy-duty highway trucks, vocational vehicles, construction machinery, mining equipment, industrial power units, oilfield service rigs, marine auxiliary diesels, power generation sets, and agricultural heavy equipment, giving fleet operators and rebuilders a reliable fitment across multiple Perkins platforms.

Featuring precision fuel delivery and high-pressure electronic unit injector control, this injector promotes finer fuel atomization, more complete combustion, and smoother engine operation. Each unit is flow-matched and tested for response and leakage, with durable metal construction and optional OEM nozzle plus AFM processing to help extend service life. The design helps reduce exhaust smoke, lower fuel consumption, and improve cold-start behavior, while supporting balanced cylinder contribution and dependable repair performance in demanding field conditions.

For long-term reliability, the 10R-8502 should be installed as part of a matched set whenever possible. Operators are advised to replace fuel filters on schedule, drain the water separator regularly, and use clean diesel that meets engine specifications. Monitoring for fuel dilution in the engine oil, scanning ECM fault codes, and performing cylinder cut-out tests can identify injector-related issues early. Always verify fitment using engine serial number, engine arrangement number, original injector number, and equipment model before purchase.
