finding parts or am I screwed

BTW, the F46D 3T95 engine is also in the prestigious YM5000 and YM5000D. That is one beastly machine!

Yes, the JD 1250 has the same engine more or less. The JD 1450 has the sibling engine, 4T95. Just a 4-cly, but uses many of the same engine parts like pistons, rings, etc. In the JD circles, the 3T95 can use the 4T95 turbo if the waste gate is adjusted accordingly. This puts the engine up and over 54Hp.

I would concur with California about the availability of parts. Even though this is a Yanmar JD 1250, not so many were made for JD. About 5,785 of them. There isn't a total production that I'm aware of for the YM5000 series from 1980 to 1990.

Not certain if the 3T95 was derived from the 3T90 aka JD 950 model. Only JD and Yanmar parts manuals could cross reference those parts. Also it would take some time doing this since JD keeps obsoleting parts and using newer part numbers are replacements. That bugs me totally.

But for now, getting the engine to run is the task at hand.

A local machine shop can get the crank welded and brought to spects, Hes quite sure he can get the parts also, this will cost about $1,400 , I will keep you posted PS the clutch was at the rivets so once I get the motor back I get on that

Up date Machine shop hit the same road block with parts, plan is see if they can weld it up and be able to use .010 over bearings that I located in Michigan, taking a while but I will check in as things go one way or the other.
