Yanmar YTG Series

The register lists here 7 versions: YTG10S, YTG12.5T, YTG15T, YTG5.0S, YTG6.5S, YTG6.5T and YTG9.0T. Engine output ranges from 8.5 to 19 hp (continuous to rated) at displacements of 493 to 1,007 cm³ and rated speeds of 3,000 or 3,600 rpm; set apparent power lies between 5 and 15 kVA (prime power 5 to 12 kW) at 220 V or 220/380 V and 50/60 Hz, dry weight ranges from 170 to 388 kg, cooling is via a water radiator.

Diesel-powered generator sets built on compact industrial engines like the YTG range serve as backup power for buildings, building sites and ships, as well as a self-sufficient power source in areas without a continuous grid; alongside makers such as Kubota and Isuzu, Yanmar ranks among the established Japanese suppliers of such generator engines.

When buying used, what counts on these generator engines is operating hours, the condition of the injection pump and cooling system, and the condition of the attached generator end, since engine and generator are usually traded as one unit; corrosion on the fuel tank and exhaust system is a common weak point on stationary-operated sets. Spare parts run through Yanmar's industrial engine distribution.
