The Yanmar L70V is a model in the L-V Series series. The engine delivers 6.5 hp (4.8 kW), has 1 cylinder. The engine is air-cooled. The fuel is diesel. The L-V Series series covers 3 models. Rated output within it ranges from 4.6 to 9.2 hp; the L70V sits in the middle of that range with 6.5 hp. Its immediate neighbours are the L48V below it with 4.6 hp and the L100V above it with 9.2 hp. 1231 Yanmar models across 70 series are on record.

Yanmar L-V Series – air-cooled single-cylinder diesel engines of the register: L48V, L70V and L100V from Yanmar's industrial engine production

The Yanmar L-V Series brings together on this collective page three air-cooled single-cylinder diesel engines: L48V, L70V and L100V. The power steps 48, 70 and 100 also appear in the L-N range; L-V and L-N thus form two parallel versions of the same displacement classes within Yanmar's industrial engines. Yanmar was founded in 1912 in Osaka and still builds its air-cooled single-cylinders for stationary and mobile industrial use today.

The register lists here 3 versions: L48V, L70V and L100V. Output ranges from 3.4 to 6.8 kW (4.6 to 9.2 hp) at displacements of 219 to 435 cm³ and a rated speed of 3,600 rpm; all three are air-cooled naturally aspirated single-cylinder engines, dry weight lies between 29.5 and 48.5 kg.

Air-cooled single-cylinder diesels such as the L-V range drive pumps, compressors, small construction machines and agricultural equipment; their independence from a coolant circuit makes them especially suited to regions with unreliable water supply or to winter conditions.

When buying used, what counts on these single-cylinder diesels is the condition of the fuel filter and lift pump, play in the crank train, and the condition of the cooling fins; on permanently built-in engines, removing the attached equipment is often the only way to see the true wear condition. Spare parts run through Yanmar's industrial engine distribution.
