We will need the Model, Specification and Serial Numbers of the engine.

The engine identification numbers appear on a decal or decals, affixed to the engine. The primary location is on the side of the flywheel cover. Other locations where the label may be affixed are the engine shrouding. Placement of the decals may vary due to OEM requirements, specific options involved and also the type of Kohler Engine (AEGIS, TRIAD, COMMAND PRO CS, etc...)
