Yanmar 3TNV Series – water-cooled three-cylinder diesel engines of the register: 3TNV74F, 3TNV80F and 3TNV88F from Yanmar's industrial engine production
The Yanmar 3TNV Series brings together on this collective page three water-cooled three-cylinder diesel engines: 3TNV74F, 3TNV80F and 3TNV88F. The figure 3 in the type designation denotes the cylinder count; the TNV range is among Yanmar's most widely used compact industrial diesels and drives mini excavators, compact loaders, generator sets and compressors worldwide. Yanmar was founded in 1912 in Osaka and builds its industrial engines partly at its plant by Lake Biwa.

The register lists here 3 versions: 3TNV74F, 3TNV80F and 3TNV88F. Output ranges from 13.7 to 18.2 kW (18.4 to 24.4 hp) at displacements of 993 to 1,642 cm³ and rated speeds between 2,400 and 3,000 rpm; all three are water-cooled naturally aspirated three-cylinder engines meeting the EPA Final Tier 4 emission stage, dry weight lies between 103 and 152 kg.
Water-cooled three-cylinder compact diesels such as the 3TNV range form the heart of many mini and compact construction machines as well as mobile generator sets, because within a small footprint they offer smoother running than single-cylinder engines and meet the emission stages required for mobile use.
When buying used, what counts on these three-cylinder engines is the condition of the radiator and water pump, compression, the condition of the injectors, and the tightness of the cylinder head gasket and oil pan; on engines built into construction machinery, it is also worth checking the engine mounts. Spare parts run through Yanmar's industrial engine distribution and through the makers of the equipment fitted with them.
