This engine has a 3/4" x 2-1/4" main shaft and a 1/2" x 3/4" pto shaft. If you buy an engine without the extra PTO shaft, you can use the side cover and camshaft off of your engine. You will have to make sure that your carburetor and muffler are set up the same as the LH195 series engine which is the muffler on the right side and the carburetor on the left as your looking at the carburetor side of the engine. If your muffler and carburetor are opposite than that which is listed, this engine will not work for you.
