stuck bolt

subby · Post by **subby** » Sun Jun 01, 2008 8:37 pm

any suggestions on getting a piece of bolt from an engine, the harmonic balancer decided to fall off, leaving some of the bolt in there

not having much luck getting it out, dont really want to pull the engine out.

What made your crank pulley (subaru's dont have/need a harmonic balancer) just fall off?

If you dont wanna pull the engine,.. just take out the radiator and the front grill so you can access the end of the crank and you will have to drill the remaining piece of bolt with a reverse drill or an "easy out"

i dont really know what made it fall off, dodgy bolt???

i've taken the radiator out and the grill, wrecked the cog getting to it, but the mechanics drill he has, wont fit in the space we made, he has tried the "easy out" option.

This happened to my eldest son on his RX7. He went to a local hire place and hired a right angle drill for the job. He ended up buying a pneumatic right angle drill later to keep for such jobs.

thats an idea, ill look into that tommorrow,
its just such a small piece of bolt left in there, could i try a shorter bolt and leave the bit in there, *cringe*

Nooooo - ten you may end up with a bigger chunk in there:)

Easy outs are all well and good however break one off and you end up with a high tensile problem as well...

I have a dremel with a carbide tip I use to slot busted studs and astray bolts. It is fiddly work and very very slow however once slotted I can use a screwdriver to remove it.

Good luck with your bolt...

the mobile mechanic guy said he thinks theres a thread lock on it, or its rusted on, lol, when hes tried to turn it, it turns the crank, so its really stuck
