Nobimmer 694 Report post Posted February 28, 2010 Ok, rounded the little allan key that holds the rotor onto the hub. Struts had been sitting for 4 years in a paddock, I should have lubed it.mmm lube. Anyways, what do I do, I just undid the big nut holding the wheel bearing on to get it off so I could get the coilovers made but now need to get it off to put the new discs on. Should I try weld a bolt to it and take it off? Or would it be easier to just buy a new hub? Cheers Ashkan Quote Share this post Link to post Share on other sites
Docile 64 Report post Posted February 28, 2010 almost had the same problem removing my rotors which was last bolted on 1995.. i ended up buying a impact driver. oh that saved my butt from head scratching. started hammering at it and it loosened LOL love that tool!! if it did no loosen i doubt it will fly off so probably safe?. but in the long run you still wont be able to take it out. better to get another hub?

dubman 39 Report post Posted February 28, 2010 Does that allen key round bolt thing do anything other than hold the rotor? It just makes it easier to re attach my wheel back on, or does it serve another function? Quote Share this post Link to post Share on other sites
Docile 64 Report post Posted February 28, 2010 (edited) from memory it just holds / aligns the rotor holes with the wheel bolts to the hub... wheel bolts does most of the keeping it together part. well that's how i see it. the allen bolt thing is shallow. prob different for the e30?

Nobimmer 694 Report post Posted February 28, 2010 I need to take it off to take the rotor off... Whats a new hub/wheel bearing assy worth? Raaaay!? Quote Share this post Link to post Share on other sites
e30ftw 410 Report post Posted February 28, 2010 Would be pretty easy to just weld a bolt to it and take it out. But I guess if a new hub is cheap enough then why not.. Quote Share this post Link to post Share on other sites
dubman 39 Report post Posted February 28, 2010 can you drill the bolt out? or is that a bad thing to do.... Quote Share this post Link to post Share on other sites
Forrest 35 Report post Posted February 28, 2010 I have drilled a couple out in my time. Also used a chisel on the head of the bolt to cut a slot in it and hit to spin the bolt anticlockwise and undo. CRC Penetrate will/would have helped. Quote Share this post Link to post Share on other sites
Nobimmer 694 Report post Posted February 28, 2010 Yeah, will ring Ray and reevaluate tommorow. Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted February 28, 2010 Drill it out - only takes 5 mins. Last time I had to do it, the head came off leaving enough bolt sticking out to undo with a pair of pliers. Quote Share this post Link to post Share on other sites
bmpower 3 Report post Posted February 28, 2010 Drill it out - only takes 5 mins. Last time I had to do it, the head came off leaving enough bolt sticking out to undo with a pair of pliers. +1 takes no time at all. Did this on mine originally and just did it again on a friends e30 3days ago! You'll just need a new bolt/screw! Quote Share this post Link to post Share on other sites
djs325 0 Report post Posted February 28, 2010 This happens a lot with old rotor bolts. Get a small cold chisel and/or a centre punch, and carve a slot into the bolt head, then rotate it gently with some penetrating lubricant (WD40, Penetrene etc) to assist. Go and get some new ones from the dealer - if you don't, the rotor will rotate slightly around the wheel bearing face and grind against the wheel bolts/studs. This will cause problems down the track that are easily avoided with a couple of $2 parts. Quote Share this post Link to post Share on other sites
tibbs.james 1 Report post Posted February 28, 2010 Sometimes you can smash a male torx bit in there and wind it out if you have to drill it out you can usually just drill just the head off and remove the rest of the threaded part with some good vice grips once the rotor is removed Quote Share this post Link to post Share on other sites
DRTDVL 0 Report post Posted March 1, 2010 Drill the head of the bolt/screw off then slide the disc over the now headless bolt/screw and then remove with pilers as above... done it on the 205, 306, and a few other cars... stupid soft screws... they arn't anything special just a countersunk screw, most hardware places\engineering bolt shops will have them.
