http://www.edlfast.co.nz/LinkClick.aspx?fileticket=eviojPE4z88%3d&tabid=3343try this link which might whet your appetite. shows twelve cornered bolts at the top of page 12. seems my supposition on high torque was close. "home" in on the link to make contact with this fastenings outlet.hope it leads to success.specialist tool shops will solve your problems for $$$$$$, but I suspect a switched on fastener man might offer economical equivalents (suitable for normal tools?) if originality is no issue.if a job is done correctly, anything can be re-done for a $. rivets (permanent fasteners) in planes, boiler bolts (PRECISION fastenings) etc, get replaced by learned people. surely the forum can turn up with a member who could help, or do that type not compute?good [luck] management!

Looks like it could be a goer.  Many thanks for the heads up, I've actually been to their site but completely missed that page.  I'll keep you posted.

Yes Gerard, I had a reply tonight when I got home from out monthly meeting: hi malcolm,,,how deep are those corrosion craters???,,often times road salts will eat under the anodizing,,,we can strip the old anodizing,,,re-anodizing will reveal every nook n cranny,,,not aesthetically pleasing at all,,,normally we then bondo the offendin gstuff and powder-coat them...we do these three piece units routinely,,i'm not at work ,,will get $$$ when i get in woodySeems he thinks I'm after getting them to do it for me but I'll wait and see what he comes up with when he gets to work.  I have also emailed BBS.COM in the hope they will come up with something.  Thanks for all of your help guys, the saga continues.....

typical BMW with nice stainless fasteners. they can be re-used with confidence. just need the correct tools and some skills.a guy with a torque wrench would fractionally over tighten all examples of the fastenings involved, to establish the torque that they are set to. this would not cause undue stress. do not use penetrating oils or lube as most reliable torque sttings are done dry. internal/binding corrosion between stainless and alloy should be minor and consistency of readings, or lack of, should allow a reliable average  replacement setting to be established.as to making good the cosmetics, modern highly adhesive bogs would do (cost effectiveness), but you would then need to cover them in typically powder coat for appearance sakes. as you know, "kerbed" alloy wheels get filled with weld and remachined and finished (polished, clear lacquer, anodised, chromed) then rebalanced. finish is mainly aesthetic, but affects future ease of cleaning and . rough/ porous is hard to keep clean. all relative.all this discussion is very academic/hypothetical. the  principles are fundamental and technology basic (not rocket level, though life is dependant upon it). we could talk of asymmetric heads/nuts on the fastenings, bog density compared to alloy etc all causing change in two plane wheel balancing or even aerodynamic resistance. comes down to $$$$$$. back to better than new or OK to ride safely. fear of the unknown is greater than need be. rumour mills talk of wheels etc flying apart, but only negligent trades practices have resulted in such (bus wheels not being tightened up). rarely has original materials failed unless HIGHLY/WRONGLY MODIFIED. close to std will be OK.

Thanks again ARTY.  I recieved an anwer from Woody's Wheels in Denver last night:G'day malcolm ,,we have the special tools for the bolts/nuts ,,got em from Snap-On if my memory serves me,,,we just put a little identifying punch on both sides of the wheels  so that everything goes to the exact spot it was before,,,,do all your work and reassemble using silicone II between and systematicallly and evenly tightening the bolts to their proper torque...we clean all th ethreads as part of the prep and use loctite blue on  the threads when re-assemblingFYI we also hav ethe ability to heliarc the deep holes and then grind/blend everytthing smooth...FYI ,,there is a special filler for use with powdercoating...This would seem to confirm all you have said, not that I needed confirmation  🙂  I managed to source a a supply for a 12 point key from the Bolt Shop yesterday and will buy one today along with a suitable socket.  They were very useful and suggestd the fastenings could be Titanium and from looking at the BBS web site it would seem that they often use those on similar car wheels.  I have emailed BBS.com but as yet no reply.Thanks again guys for all your help and advice.  I will keep you all posted.

Update on the BBS wheels.  Finally took the plunge and after buying a couple of 12 point tools (thanks Gerard) I undid the fasteners holding the hub to the rim.  Didn't want to separate easily but after a little warming with the hair drier (sorry Jean) and a tap with the mallet the hub dropped out.  All looks well and the rim is with the polisher.  The fastenings look straightforward with the nuts possibly having some sort of restriction at the end as when fitting them together they are quite loose until the very end when they tighten up quickly.  My good friend and neighbour Rob will oversee the refitting at the weekend.  Then it's a new tyre and back on the bike for a test ride.  If all goes well the back one will be next.

Received a reply from BBS Wheels last night, it's about what I expected: Dear Malcolm, thank you for your email. Am I right that we are talking about original BMW motorbike wheels? If yes, I need to ask you to contact BMW directly.We need to inform you that it is not allowed to disassemble multipiece wheels which are produced by BBS. A disassembly of the parts is not allowed and will terminate the approval for road use. For that reason and for reasons of safety and product liability we neither inform any third party about technical details of our wheels such as the torque setting of the connecting bolts nor about any other technical data concerning the assembly or disassmbly of BBS wheels. We kindly ask you for your understanding.  Since the wheels are original BMW wheels your local BMW might give you technical support.I am sorry for not being able to give you a more favorable reply.If you have any further questions please do not hesitate to get in touch with us again.

Yeah I had the same response when I was playing with the abs unit I wanted a new computer and tracked down the oem manufacturer and got told the same story. They must have a pretty tight contract with them.boGSer

This is Germany you are talking about, they don't do No.8 wire. Maybe that's why the have fewer leaky buildings as well. But it's understandable that they don't want to be involved, as they have no control over the quality of workmanship. The TUV wouldn't even let you polish the wheels. But hey, you pays your money and you takes your chances.

If their workmanship was good there wouldn't be a problem Alex.

Yes, you'd expect the surface coating to stick better than it does. However, I've heard that some of these problems relate to their efforts of trying to use environmentally sound methods. Some of these just aren't up to it. The also seem to have or have had problems with the black dye used on jackets and pants, as that stuff fades. I guess you've seen some of the chromed wheels on the cruisers, they are even worse. They seem to be competing with $1500 Chinese scooters. Of course it's also possible that the company is now being run by accountants instead of engineers, like it used to be. I've been very happy with my 1150 and the only finish that's come of are the bits that where in occasional contact with the ground. I hope your wheels will turn out well, you seemed to have done all the sensible research. Getting second person to check everything is also a sensible decision. I guess seeing how true they'll run on the balancing machine will also be a good indication of how well everything went together. I guess you're not likely to hoon past the Autobahn.....Cafe doing a 180km/H :-).

I guess you're not likely to hoon past the Autobahn…..Cafe doing a 180km/H :-).You're dead right Alex but one doesn't want ones wheels to disintegrate at any speed eh.  :-  The thing about them (BBS) not giving any specs for their product is really over the top and I wonder if it's just to force owners in to buying replacement parts.  Surely they could cover themselves with a well written waiver then sell the fastenings or give torque figures to those who felt inclined to do repairs themselves.  Clearly there are some who have done repairs or customized these wheels quite successfully.  Ah well let's hope I don't regret this.  My headstone could be a nice shiny BBS wheel  ;D

When I run into that kind of stone wall I always wonder if it is because they built them to somebody else's specs, with which they were not completely happy?  Helluva lot of builders knew the houses they were putting up for developers/architects/keep-up-with-the-Jones's-nouveau-riche knew the places were gonna leak, but everybody that could afford to splash out on the latest fashion wanted one.  Were they meant to turn them away and go broke because they didn't like the specs?

Yes, of course. It's called ethics and morals. If you know better, you've got to tell the client. But I suspect a hell of a lot of people who called themselves builders weren't really, more a case of the one-eyed leading the blind. I think BBS just doesn't want people to mess with their wheels and potentially get hurt. At the end of the day their name will be mud. It's probably fair to assume that the wheels can be rebuilt by a competent person, but they have no control over who does it. Wouldn't you do the same?
