Hey Jerry, I know this is an old post but old stuff can be new stuff when we have a new problem. My engine was sabotaged (sugared or water or both) and all the rings seized and my pistons are scratched. Well, anyway, I ordered a shop manual and kept running across the E3CD engine number for my Iseki engine. My tractor, by the way, is a Massey 1250. However, on my engine block it says E3AD1, which according to your info, is an 1140. Do you think I have the right engine for my tractor? Another question, for anyone out there really, where can a man find a good engine overhaul kit that won't break me up? I'd need gaskets, bearings, pistons and rings. Thanks.
