Complete your full 3-cylinder injector service in one order. This 3-piece aftermarket fuel injection nozzle set is precision-matched for the Yanmar 3TNE68C, 3TNA72C, 3TNE74, and 3TNV76 engines — and their Komatsu equivalents, the 3D68E-3 and 3D74E-3. These compact 3-cylinder diesels power a wide range of mini excavators, compact tractors, forklifts, and utility equipment. Replacing all three nozzles simultaneously ensures uniform fuel delivery across every cylinder, eliminates the risk of cascading failures, and maximizes the value of your service interval.
