Farmall H Questions?

Posted by Mike in MI on April 27, 2013 at 19:31:43 from (74.36.237.161):

I'm trying to help friend on his farmall H doing a Major O/H on it. He asked if I would help him and I said I would. Actually in this case it's blind leading the blind as he's not familar with the O/H nor am I. I have a question on the crankshafts? I"m finding out that there are (2) different sizes of crank shafts that put in the H"s? On Rod journals I calipered 2.250 O.D. I think his H is a 1940 and from what I seen of it so far it"s all original from when it was bought new? It has the high dome pistons which stamped std. Rod & Mains brg are coming out std.

What he plans on doing is going with a fire crater piston sleeve kit. I asked him today if I mic the crank for out of round journals he may need to have the crank turned? I must of hit a nerve or something cause he said it won"t need to be turned and just put (std) brg back in again.
Well I guess it"s not my tractor but to me if you was to spend that kind of money on a O/H and only Half A-** it to me you might as well left it alone! Anyways I"m going to ask this question as I don"t have a tolerence book in front of me on what you aloud as far as taper on journals (+ or -) limit.

I done 4 O/H on oliver tractors and only one of them only need the crank polished and gone back to a standard brgings. The others had to be turn.010. I guess I"m more fusey on things more that what he is. I guess I"ll keep my mouth shut and go on what he wants to do right or wrong.

Another Question: He has not taken out the cam yet but I told him it be best to put new cam bearing back in and he said he did"nt think it would need them. Question: How many cam bearings are in a Farmall H?

Thanks for your help on this subject!
Mike
