>>So I just got this 1950 Super A white demo. And I also have a late '39
>>Farmall A (some books call it an early '40) that I have been working on. 
>>The
>>crankshaft, sleeves, and pistons have been installed, the rods just have to
>>be bolted to the crankshaft. Main bearings have been torqued to spec.
>>
>>I never had intentions of keeping this A once it was done. Figured I would
>>sell it. Also figured since it was just a straight A, no hydraulics, no
>>nothin, I probably wouldn't make back what I have spent on it. It has no
>>hole in the bell housing for the starter, but the bad thing is it 
>>apparently
>>got a "service engine" from IH at some point--block is a '42 by the casting
>>code and there is no serial number on it. Either way, the engine is not
>>"original."
>>
>>So I have started thinking, the white demo is a "bucket list" tractor for
>>me. And, I'm on a serious budget these days. So why couldn't I take the
>>overhaul kit I have for the A, and use it for the Super A? Only sticking
>>point is the crankshaft has a totally different part number according to 
>>the
>>caseIH website. I haven't had time to check my first edition Super A parts
>>book against that to see if the early Super A's might be the same. But what
>>in the world would be different between the crankshafts between these two
>>tractors? Regardless, I am thinking I can use everything in the overhaul
>>kit--provided the crankshaft journals are turned to the same measurement as
>>in the A. The kit came from the local parts store, it's a Tisco kit but
>>according to their website it works for all the A/B/C series tractors. Only
>>thing I would need is new o-rings for the sleeves, and transfer the pistons
>>over to the Super A rods.
>>
>>If I did this, I see myself parting the A. It has a nice .20" ground crank,
>>(assuming it won't work in the Super A)overhauled cylinder head, and fairly
>>nice sheet metal. The block has been through the machine shop--cleaned and
>>fluxed--so it would be nice. The grille is not correct for the early dzus
>>fasteners, so I would probably keep that for my Super A. I have always 
>>heard
>>that "the sum of the parts is worth more than the whole," and I feel like
>>early A parts would be worth a little more, but who knows?
>>
>>Am I missing something? Doing a overhaul kit swap seems way too simple. I
>>hope I'm not talking out of turn.....I am hoping maybe to get her running
>>this weekend, and maybe the engine will be in real good shape and won't 
>>need
>>overhauling more than maybe rings.  Usually that's not how my luck runs
>>though!
