25 - 36hp Camshaft

Camshafts were supplied from the factory with gears that had slightly different sizes to fit the specific engine. The only way to know what size your motor used originally is to visually inspect your old camshaft or trial and error. The camshaft gear will be marked with the size. Be careful not to confuse the "0" used to identify the timing mark with the gear size. Generally the gear size is crudely stamped in the face of the gear.
