Split Rim with a sheared bolt

[bony_13]

So I have managed to shear a bolt when torquing up my Style 108's :x has anyone got experience of getting this recovered and who takes on this kind of work? I'm assuming it will be a drill out and re-tap operation.

Also I was using 30NM of torque after a lot of research - is this correct?!

If you take it to any good machine shop they should (hopefully) Be able to drill into it and use an easy out. Or left handed tap. I can send you the tools if you want to have a go your self?? That should save the thread if that fails spark eroding can get the core of the bolt out and it should be able to still save the thread. Re drilling a bigger size and re tapping is the last resort.

Thanks Mat, I'll do a bit of research. My dads place would have done it had he not retired and sold up -selfish!!

I'm worried about having a go myself, becasue as he says, the bolt is tougher than the alloy surrounding it, leaving little margin for error.....

I'll let you know if I need the bits. I might be able to access a pillar drill which would be a massive help. Did you get your pliers back ok?!?!

when you say sheared... do you mean the head came off? or the tool now spins inside the head?
If the head of the bolt came off then you should be able take all the other bolts, pull the star off and then use a stud extractor to get the offending bolt remnants out.

Yep got them all back

I wouldn't want to attempt it without a pilla drill.

Yes the head sheared off, leaving a threaded section sitting in the hole.

I'm running around on an old (grey primered!! 8) ) MV1 alloy now so I could possibly take my time and have a go myself. That would give me time to source new bolts as a few of the heads are quite rounded now.

Stripped and rebuilt many 108's and the above is spot on. Remove the other bolts and use and extractor or even grips on the stud if just the head came off, which is where all the broken one's Ive seen break.

If the stud is spinning you have a bigger issue as they tend to mushroom in the alloy and will need drilling out and the possibly even a helicoil. If that's happened then give in and buy a rim off ebay and rebuild with your star

Thanks for all your help gents.

@cj10jeeper - What torque have you used on your 108's in the past? the most consistant figure i found under research was 22-24lbft which I took to use 30Nm on my wrench.

 

[cj10jeeper]

30 nm sounds ok to me. I use 'feel' for things like this and retorque after 500m

Still stuggling with this, despite all the great advice

I now have a wheel with two sheared bolts and three rounded heads :-( In trying to extract one of the rounded bolts I actually snapped the easy-out tool I was using :?

Got a friend looking at this but half expecting to scrap the wheel. May just ditch the 108's altogether and try and claw back my money where I can

 

[Machine monkey]

O dear!!

What have you got invested in them? Just asking as i might be able to suggest a plan. A machine shop could get them out but is it worth spending the money? A machine shop will be charging at least £50 an hour. And there wont be many wanting to take on a job such as this so they might bump that price up to make it worth there time! Its a tricky one that's for sure. Surly you can just buy another wheel?

 

[bony_13]

Well If we can't sort it in my mates workshop, I'm going to put the wheel on ebay as scrap. Along with another that is making some 'unhappy noises' (thats if I cant re-set those bolts and cure it).

Likely I will be selling one complete set of problem free 108's in need of refurb. The selling a further 2 or 3 refurbished (depending on above).

Looking at some style 32's or BBS reps. It's not just the money that has me annoyed, its the fact I'm not happy with my car and not enjoying driving it at the mo

O dear how come??? I was really unhappy with mine and thought it was not the car i was expecting. And that my previous e46 was much better. Turns out it was just either the track rod ends or more likely the lower control arms. changed them just had the tracking done no alignment yet. It a hole new car. What are the issues you have with it?

 

[bony_13]

Oh no mate, I'm happy with the car overall. It's just at the moment I have on my car.
1) one temporary wheel on the front - which although the same size and tyre size is a different design (MV1) and on a non-runflat tyre
2) one rear wheel wheel that makes a tyre squelching noise outside from the car (which sounds like a rumble inside).
3) Two other wheels that are fine! :lol:

So until I get both these sorted I'm tip-toeing around and not able to push the car and have fun. Just want it sorted
