  1. Sleeve and block damage

    Hey guys some questions for those of you who may have seen or run into this. I had all cracked sleeves on my 450D (i assume starting fluid use as the culprit) so i pulled them all and as i expected there was a mark on the block everywhere the sleeves were cracked, most are so minor you cant even catch with a finger nail and appear to be more discoloration then an actual mark. Those actually appeared to come out with some light scotch bright and oil. There is one however that you can just barely catch with your finger nail, and 1 that is even more significant. The worst one was where the sleeve cracked in a U and created a "tongue" so to speak that was relatively free to travel in and out horizontally with pressure change in the bore. The ridge left is roughly .002-.003 (Ill get a hold of a dial bore gauge and check for sure). I know the "right way" is the hard way and requires pulling the motor and having it bored and use a custom sleeve replacement or a repair sleeve and a stock sleeve. But for those of you that have seen this can you scotch bright/emery the ridge out and get away with putting in new sleeves? I would assume if you just left it as it is, it would really mess with the heat transfer as well as create a pressure ridge along the sleeve leading to cracking again, so i figured if you at least smoothed it out it would probably hold. I think the motor was ran with cracked sleeves for quite a while considering the blow by the previous owner described and with what i witnessed before tearing into it. Its not a high HP motor nor is it throwing on a 4 or 5 bottom plow going all day, but it does do a fair bit of cutting, raking and once in a while baling. I also have thought of a cracked block, i have talked to a few other gas start engine owners and they have run into the same problem and when looked at by a machinist it was not cracked. I never had any oil water mixing either so i think (hoping) i'm safe. Thanks in advance.

  3. Farmall 450 diesel

    Hello some quick questions from those out there with some more wisdom then myself. I am in the process of possibly purchasing an old farmall 450 diesel. A short story long, as a young boy riding the bus to school I passed this farmall 450 sitting by a neighboring farms barn everyday and dreamed of someday owning my own. It was certainly the highlight of the ride to school. That was just under 25 years ago. Just the other day I finaly decided to stop in and try to find out the story of the old 450 and if it would be for sale. Surprisingly the owner was more than happy to tell it's tale and said he would part with it for 1k, due to the fact of when he parked it he had just put thst or more than that in fresh tires on. He said it used oil when it was parked and is probably due for a rebuild but still ran strong, the TA worked and that he parked it due to coming across a few good deals on newer larger (green) tractors. He said that he would be more then happy to help get it fired back up again prior to hualing away. A few questions for you all.. What would be considered a fair price? What all must I check before trying to fire her back up? Lastly looking for overhual parts they are far and few between, any experience here in the best sources for parts vs price? Anything in particular to look for on these tractors when buying? ThanksThanks in advance! Sean
