I"d like to restore this farmall A this winter. Will JB do ok on a rough restore? Crack is on the LH side on the front. Typical area. Should I replace the block (kinda costly), weld it (kinda tricky), or JB it and grind it smooth?
 
If the crack is on the side of the block, behind the carburator, and the block is OK otherwise, I would JB Weld it and grind it smooth. There are a lot of tractors out there with that crack.
 
Depends on how bad the crack is. I have a block from a B that is so bad that I would not trust it. Or should I say I parted the tractor out because of it and now that I have opened up the engine I am happy I did it that way because it was cracked so bad that the JB weld that was on it only hide the real problem and the crack is so bad it would not have lasted very long it used much if any
 
If the crack isnt realy bad so the block is cracked between the cycls there are different stuff that will last forevr. I have one that they welded and realy made a mess. I ground it down got rid of the mess and then used ruvver cement that they use when installing a new windshield. Let it set in the sun so it got nice and warm then spread the stuff on. That was 10 yrs ago and has been on several rides and other uses no sign of any leak.If tou will rough it some after appling to look like cast it should last forever and you cant even tell its been fixed. The JB will want to run when setting up but you could use a couple of treatments. I have also patched with fiberglass and that works also. Have the one i mow with thats been that way for many yrs and will hold up.
