Engines and motors for construction equipment: gas, diesel, and electric in one section. Honda GX engines from GX100 to GX690, Kohler CH440, Yanmar L70 and Kubota OC95 diesels, electric motors, and the Hatz filters and spark plugs to service them.

Read the spec plate before you order
Every engine here is sold by its full factory spec, not just the family name. On the diesels, the plate carries model and spec together — L70W6E60C8HABS on the Yanmar, OC95-E4-D1-Q-L1 on the Kubota. On gas engines, the suffix after the GX or CH model sets shaft, tank, and controls. Copy the code off your old engine's plate or barcode decal and match it character for character. For filters and pumps, go by the number stamped on the old element, not by eyeballing the size.
Honda makes up most of the gas side here — Honda engine parts carries the model-by-model carburetors, coils, recoils, and gaskets behind these engines.
