original 0R-8682 Engine Parts Mechanical Fuel Injector Assembly for 3114 3116 3126 320B 325B 325BL M318 Excavator original new injector

Engineered specifically for the 3116 and closely related 3114 and 3126 mid-range diesel platforms, the 0R-8682 fuel injector delivers OEM-level fitment with direct-replacement seat geometry that drops into the cylinder head without modification. A precision-machined nozzle produces a finely atomized spray pattern optimized for combustion stability, supporting consistent power output across the heavy industrial duty cycles demanded by construction, mining, and genset applications. The hardened steel body and corrosion-resistant coating withstand sustained operating pressures of ≥1500 bar while resisting high-temperature wear, ensuring long service life in punishing environments such as loaders, backhoes, excavators, graders, track tractors, pavers, and compactors.

Every unit is tested for flow rate, seal integrity, and spray pattern before shipment, giving fleet operators and rebuild shops predictable performance from the first start. The 0R-8682 is cross-validated against multiple OE and aftermarket references, including 127-8216, 127-8222, 107-7733, 127-8205, 127-8213, 114-4508, and 196-1401, simplifying sourcing across OEM, reman, and aftermarket channels. Standard mounting dimensions and the standard high-pressure inlet configuration ensure seamless integration into existing fuel system plumbing without additional adapters or calibration changes.

For maximum durability, follow a disciplined maintenance schedule: inspect spray quality every 500 hours, perform full flow and pressure tests within the 750–1000 hour window, replace fuel filters on the engine manufacturer schedule, and rebuild or replace the injector whenever power loss, increased fuel consumption, or rough running is detected. This preventive approach keeps 3116/3114/3126 powered equipment operating at rated output while minimizing unplanned downtime in heavy industrial fleets.
