Nate, Here are my thoughts on your question. I would think that there should not be a problem with shortening the cam shaft and replacing the side cover with one that doesn't have the hole for the pto. However, the length of your camshaft after it is shortened will have to be within a thousandth or two of the length of a standard camshaft. Secondly, the cutoff end will have to be done on a lathe and the end chamfered and polished. Otherwise you are going to get excessive end play (horizontal movement) of the camshaft and if it has a rough end (because it was cut with a hacksaw) it is going to chew the bushing in the side cover and you are going to have problems. That's my two cents worth. Ogy
