Just bought a B and C to restore.

Both blocks have small cracks between the cylinders. Are these blocks still usable or fixable????

The cracks are very common,the metal is so small there that they all crack.You should be able to still use it,but if you replace the sleeves you may seperate the crack and the top won't be flat anymore.They are repairable,I had mine repaired by someone who drills a series of holes threw the cracks and installs threaded plugs in them.What an incredable job he did,it is perfect and he said it will never crack again.They use this method in industry to repair cast machinery.It cost me about $150.00

Its pretty common to find those,I have been told as long as the crack does not go all the way thru,the block is still good.In the last four tractors that i have broken down for parts ,only one did not have a crack in between the cylinders.

Dave, Those are common cracks,normally they don't leak!If it doesn't need to get resleeved I would use them,If it needs to be resleeved I would not,I would locate a block that is not cracked. My .02woth Justin NY

For what it's worth, I pushed new sleeves in my block and didn't have any problems. The cracks didn't change any, and she seems to run fine. I did put a coating of Permatex on the deck of the block before I put the head gasket on just to help seal the head gasket a little better between the cylinders. Just thought I'd run that by ya before you went out to look for a couple blocks to purchase....

Dave, Both my B and C have small cracks between the cylinders. Doesn't seem to be hurting anything. I am still using them the way they are and haven't had any problems yet. Hope this helps, TractorMike

Seems to be a common occurance from what I learned here on the board. Had a couple small cracks between the cylinders on my B when I got the head off also. Seems to be okay so far though since the rebuild. I think a couple fellows here on the board said if they're real wide, they could be a problem. Dick L. on this board has a fix for the big cracks. Pretty slick how he fixes em'. He installs a bolt right through the block and pulls the block together. He may see your question and toss a couple of his pix over your way for ya. But if they're small hairlines, I wouldn't worry bout' em.... Steve B.
