[AT] Farmall C123 block cracks

[Easley, Greg]

I did a water jacket repair on my nephew's Farmall C nine or ten years ago.
Like the guys said, grind a vee along the crack and drill the ends.  Just
doing that will hold it for awhile.  If you want it to last cut a patch out
of 1/8" steel plate 2" longer and wider than the crack.  Drill for 1/4" cap
screws, tap the holes in the block, glom it with red RTV and fasten it down.
Don't forget to JB weld the crack, and let it cure for a day, before you apply
the patch.  Do it right and it's a permanent repair.

My first antique tractor was a Farmall 'A' with a water jacket crack.   My experience was JB Weld holds only up to a certain number of thermal cycles, and then it starts to leak again.   For me, that was about one season of mowing.  Maybe someone better than me at applying it  could get more permanent results, but I couldn't.  

 I know you use your machines too so I suspect you will be applying every winter.  But that is better than running out of water because the leak got ahead of you though.

Good luck!
