Engineered for demanding industrial duty cycles, the 0R-8682 high-pressure diesel fuel injector delivers OEM-level fitment and precision atomization for 3116, 3114, and 3126 mid-range diesel engines. Manufactured from hardened steel with a corrosion-resistant coating, this injector is validated against a broad cross-reference catalog — including 127-8216, 127-8222, 107-7733, 127-8205, 127-8213, CA0R8682, CA1278216, CA1278205, CA1278213, 114-4508, and 196-1401 — ensuring reliable interchange across OEM, remanufactured, and aftermarket sourcing channels.

Each unit is bench-tested for flow rate, sealing integrity, and spray pattern uniformity to support stable combustion, lower emissions, and consistent power output under high-load operation at pressures ≥1500 bar. Typical applications include loaders (924F), backhoes (446B), excavators (320B), graders (120H), track tractors (D6M), pavers (AP-1055B), compactors (CP-563 / CS-573C), and heavy industrial generator sets. The design also serves mining/quarry machinery, on-highway diesel trucks, and agriculture and forestry equipment where injector durability is critical.

Installation requires clean seat surfaces, factory-specified sealing washers, and hold-down clamp torque of 25–30 Nm. For maximum service life, inspect spray quality every 500 hours, perform full flow and pressure tests within 750–1000 hours, and replace fuel filters per engine schedule. Packaged in OEM or neutral cartons, this injector is ready for global B2B fleet, workshop, and distributor supply programs.
