Here is the story. First I,m no diesel mechanic. And from what i am reading on this site many of you are knowledgeable about these fordsons so this may intrest you and help me a great deal. I,m a machinist and hopefully I will be able to follow youre instuctions and get this old beauty to run again.... Aquired 1956 major engine#1398184. Started up fine, sounded ok but spueed black smoke unbelievable and I mean alot You couldn,t breath around it.It rained diesel.With my limited knowledge and before I found this site. I started to mess with it from data I found in some partial old manual. First I started to adjust the amount of fuel from each injector by moving each adjustment. I did this while it was running by sound and site. It definatly helped. you could see the tractor.By the way the cover and pump had been messed with before I got tractor so I was asumming previous owner couldn,t fix. Next I adjusted control shaft on pump, again by site and sound ,now you could actually sit on tractor when it ran but still smoked. Smoked more at idle. but still alot. After doing this sequence a few times it got a little better. Again no problem starting and didn,t sound to bad. A little backfiring when backing off throttle. Then set timing according to book. Had most of the pages in manual .Didn,t seem to have too much of an effect. Advanced timing a few degress seemed to help .Could drive tractor and breath at the same time now. Could work with backhoe but still not right. Still too much smoke but 50 percent better than it was. Seemed that tractor was lacking power,unless I incresed fuel delevery from main control shaft on pump. But then it would smoke more. Then I checked injectors by removing one at a time and watching them fire. atomization seemed ok (from a distance) and injector tips looked ok. reinstalled. After all this it still was not right but it was useable and it wasn,t raining diesel fuel upon you when driving tractor. Next Used tractor over the next couple of weeks. Drove 16 miles to property we bought to dig percs. Spent the day digging and drove it home again. Tractor set for about a week. Started tractor again and let idle while I was getting stuff ready in the garage. Tractor ran for about 20 minutes then came to a screeching stop.Wouldn,t turn over untill cooled, but then would not start again. Well by now you know what happened but at that time I wasn,t sure what happened but I kmew it wasn,t good. So I tore down tractor.. Water in oil pan,quite a bit, Two rods spun Crank bearings wipped out and crank .030 under.. Even worse Block broken away just beneath oring groove for sleeve seal on three cylinders, for an area of about 2inches circumfentially.This had been this way7 for a long time. I think over the years it was patched up with some kind of putty as I found some in the pan. So to fix the problem Here is were I stand now.. I made aluminum molds of the oring groove from the good cylinder . Put them in the three that had broken cast pieces gone held in place with jack bolt and silver soldered(braced) up against the aluminum to reform the oring groove.. ( I had the block baked and proffesinally cleaned to help in this repair process) This worked suprisingly well. The sleeves slip in nice and soon will be ready to start rebuilding. I am waiting on new crankshaft. And I can,t find sleeve seal or oring which ever they are yet. But after I get her running again I still have the smoke issue. I now alot of stuff I did was probally not right so your help would be greatly appreciated. Here is just a few of the things I am assuming... I don,t think the governor works. Its vacume with two pipes from intake. The injector pum[p is a simms.. I could use a ring gear if anybody knows where to get one and a throw out bearing... I will need some guidance I,m sure when I start to reinstall motor and get running . I will post for help... Thanking you in advance ... Mark
