Do the job right the first time -no shortcuts; they always come back to bite you later anyway. DO NOT BUY ANY PARTS until you get the engine torn down. Then you'll know what size pistons and bearings to buy. Once torn down a good machine shop will need to boil the block. they will remove liners, if there are any, and check cylinder bore sizes. They will also check for cracks and any other defects. If you never did a rebuild before, I suggest you leave it to a good shop. They will check the block, check the head, turn the crank and purchase the correct kit for you. the original N engines had steel cylinder sleeves until early 1950. Then they were cast iron. Unless you know the history of the tractor, who knows what, if any, sleeves are in it now. The steel sleeves are a moot point anyway as they don't make them anymore. You can only get cast iron liners. Steel was a poor choice to begin with and Ford knew that. Why else would they mark the s/n with a star symbol to designate it as such. What is the tractor serial number? You do know that all 9N and 2N models, 39- 47 had the serial number prefix of 9N; there is no such thing as a 2N stamped s/n? If indeed a '39, is it an aluminum hood model? Are you restoring it? 6V or 12V? Can you post pictures? Where are you located? A word of advice: A decent rebuild will cost $1500 - $2500 using an experienced shop/mechanic.
