Easy out is drillling bolt thinner instead of gripping and pulling it out our local mechanics for repco, told me torque settings were 50nm then 100 nm when it broke i rang holden to find out its 18-22nm then 1/4 turn, so id say its snapped at about 30-35nm with 243 applied,
when you run out of other options you could try either - using a small sharp punch and tapping the bolt in an anticlockwise direction. This should slowly rotate the bolt until theres enough stud sticking out to grab with vice grips. Or, drilling out the bolt to just below the diameter of the thread. then you should be able to pull the remaining metal out in pieces.
Is it possible to remove flywheel from engine and attack the remaining stud with flywheel removed.?
yes its possible thats how i have it i have tried tapping anticlockwise, but just seems to bur it off, i cant put helicoil because this is crankshaft that would not be wise, and i dont know whether possible to drill it out and tap threaD IS THERE SOMEONE WHO WILL COME AND DO THAT IF I PAY THEM,??? someone must do that shorely, but i haVE to move in aweek and the car has to go back together and be running, what sort of person taps threads
