The Perkins 10R-8502 electronic unit injector is engineered as a direct OE replacement for Perkins C15, 3406E, and C16 heavy-duty diesel engines used in trucks, construction, mining, and industrial power applications. Authorised under the primary OE number 10R-8502 / 10R8502, this EUI unit is cross-referenced to an extensive Perkins and Perkins-compatible part range, including 10R-0958, 10R-2780, 0R-4893, 0R-4118, 0R-4668, 0R-9258, 0R-9259, 102-6230, 117-1146, 117-1148, 118-2489, 118-9035, 130-9987, 152-3680, 176-1145, 176-1160, 191-3004, 191-3007, 211-3024, 211-3027, 20R-5809, 1Y-3822, EX630958, R-10R8502, 10R8502R, and 10R8502RFM, supporting replacement across 1995–2003 model-year engine builds.

Manufactured to OE-style specifications, the injector delivers high-pressure fuel atomisation through an electronic unit injector control strategy, helping to maintain smoother engine operation, better combustion efficiency, and reduced downtime. Each unit is built with durable metal construction, may use OEM nozzles and AFM processing, and is available as a remanufactured or replacement option with flow-matched set availability, tested injector response, and leakage testing performed before shipment.

Proper maintenance is critical for long service life: replace the fuel filter on schedule, use clean diesel fuel that meets engine requirements, drain the water separator regularly, and keep the fuel tank free from rust, sediment, and microbial contamination. Monitor engine oil for fuel dilution that may indicate injector leakage, scan ECM fault codes when injector-related symptoms appear, and perform cylinder contribution or cut-out testing during rough-idle diagnostics. For balanced fuel delivery, injectors should be replaced as a matched set. Verify compatibility by engine serial number, engine arrangement number, original injector number, and equipment model before ordering.
