[AT] JD 318 head bolts

[Claudeprintequip at aol.com]

I have used a small hand held propane torch to heat steel bolts in aluminum  
then tap the bolt head with a ball peen.  They seem to free up pretty  well 
after that. How hot should the bolt be?  The guy who taught me  said they need 
to be "Just about right".(??)  I never did try to get one  very hot, just hot. 
It doesn't take a lot of heat to melt aluminum.    Since your bolt heads are 
gone you might try heating the bolt end then peening a  center into the broken 
bolt with a punch.   Then drill a hole in the  bolt and try a bolt extractor. 
Never did this with a JD 318.  Doesn't  look like you'll loose anything but 
some time by giving it a try.
