What do you do if you snap off a stud while splitting open
a cast aluminum tank.. out of the box thinking required
Fasten tank halves together using the other
bolt holes. Make a snug fitting drill sleeve to guide
drill into broken off stud….I used several different
sleeves to drill successively larger holes.
CHECK what drill is doing by taking tank apart
to be sure drill is not wondering.
Do NOT drill into threads.
Tap new thread also using tank to align
tap so it creates a thread straight and true.
I did not attempt to back out the remains
of stud. I had used up my supply of good luck
getting things acceptable…going for perfect
involved risking all I had gained.
