alternator bolt from hell broken off in head

[moparstuart]

coming home from a car show saturday I had an alternator bolt shear off in the head
, we heard a rattle and stopped and duct taped (200 mile an hour tape ) it to keep the alternator on so we could get the 30 miles home .

we tried to drill it out with three different bits and then went to a diamond tipped bit but it was so hard it was not coming out

 

[moparstuart]

:jester: we made a hole but the bolt tip is still in there

 

[moparstuart]

we found a alternator mounting bracket off another motor that mounts to the other bolt holes in the head and has a pre threaded nut welded to it to mount the alternator

 

[moparstuart]

:jester: alternator mounted back on fine but now it wont charger ???
I thought it might be a ground problem , but now i have scraped off paint and re grounded everything well
still no charge ?
charged voltage reg also just to make sure ?

:cheers: so tonight i pulled the alternator back off ,it has a life time warranty , will have it tested tomorrow

It will jump the gauge every once in a while but if you turn the lights on or put any load on it the gauge never moves ? gauge never move but once every minute or so with out a load then goes right back to discharge ?

That was one hell of a pickle! Were you able to use an extractor bit?

only could get a really small hole drilled , the easy out would bite for a second and then just eat the metal away around it so no hole to bit into again , was very frustrating. this bracket worked great but now it just wont charge ?

Hmmmmm. Did the alternator fry a bearing and cook itself and that's what caused the bolt to shear off???

Best bet for something like that is a left hand drill.

new alternator installed and it charges great

this one is solid state with a circuit board but not for full race like the blue one
