[Farmall] Manifold Studs

[Larry L Hardesty]

John,  Thanks,  I got the nut off the one stud by heating it up and 
letting it cool.  The real challenge is getting the stud out that is 
broken.  It broke off far enough up that I can get a nut on it.   I 
probably will take the tractor to my nephew and weld the nut on and work 
from there...hoping I do not break the stud off further down.  It probably 
has only been a in the tractor for 61 years....you would think they would 
make them to last!  : )

Larry, try heating the stuck nut to red hot and then let it cool 
down--maybe a couple times....applying a good penetrating oil before and 
after.  It should break loose enough to work it back and forth with 
penetrating oil.  Usually best not to try to turn off a red hot nut 
because 
it will often gaul (weld itself) to the stud.  With the broken stud, grind 

down the broken face of the stud so you can center punch it exactly in the 

center and drill it with a small bit, followed by a tap-size bit.  Use 
good 
quality bits that can withstand the hard steel of the stud.  If retapping 
is not successful you can drill and tap it to the next larger size--or use 

a heli-coil.  Good luck with the nasty things!  John W.
