    What do they charge for labor, $300/hour?

    My '05 has cracks at all fastening points. I asked A&S about replacement and got a, "Sure we'll replace it for you. $245.00 for the part plus labor." I asked if a critclal piece such as the flang shouldn't be expected to go more than 60K, I got a shoulder shrug. He did check, and low and behold there wasn't even an advisory from BMW about the issue. Seems a safety thing, but who knows what BMW thinks.
    Another point; I had them replace the output shaft seal and bearing 10k ago. They fucked it up and had to re-do the thing. Probably pissed em off and the mech put a few pounds more torque on than he should have. This last is my assumption and not proven fact, but I use a torque wrench on all critcle tightening.

    are you serious Clark? 245$? I have yet to respond to Battersea BMW here in London about the bike and they have not called me to ask yet. I need to make some phone calls to my shop that i used in Chicago and see what they would have charged me as i trust them.

    This is a great resource thanks to all.

    Sorry, that is hard.

    If I was able to do this any competent mechanic will have an easy time replacing the flange. I&#8217;d skip the dealer and find someone else to do it.:deal

    Directions for R &R on the flange can be found in marchymans thread. Below is a link

    My dealer - replaced it no questions asked...

    "Of course - it is a safety issue" Also - considering BMW are updating them and as noted a steel one is on the way - it is hard for them to say anything.

    The drill at a dealer is - when there is a question - dealer just does it or they call the national cust service rep and "they" make the call... if your dealer doesn't even call - you get nothing.

    I'd call BMW and scream and yell.... tell them you almost fell off on the highway due to vibration...

    The part - if you want to do it at home is very very easy to replace - easier than changing a tire for sure.

    Heat gun or small propane torch - a small cookie sheet to deflect heat if you use the torch and a harbor freight puller set. I got mine from Princess auto for $70 bucks and it can be used for a bunch of other things. Heat it up to 110c I think and it slides off. Put the new one in the freezer (sort of helps) and it slides on easy... Put the clip back on and wheel and you are good.

    Because I was in another city - my shop trusted me and sent me the replacement - and just asked I send them the bad one back.

    Putting the new one in a freezer makes no sense to me at all. Are you sure about that? :huh

    Putting it in a freezer would shrink it and make it harder to get on.

    Did you mean to say to put it in an oven for a little while to get it hot & expanded to make it go on easier?

    I just picked up the new steel flange and spacer today for my '05. Hansen's of Medford, Oregon got it for me at no cost from BMW even though I am the bike's third owner. Eight of ten holes in the original aluminum flange for wheel and disk brake fasteners were cracked at 29K miles--yes, a safety issue!

    Instructions say to heat flange to 130 degrees Celsius for reassembly. Will give it a go tomorrow.

    "Easy Peasy," that is. After lining all my proverbial ducks up in a neat row--heating the new flange for a half hour in a 350 degree oven (three page instruction sheet calls for 130 degrees C.), it slipped right on. All but the last .020". Merde! So I had to go into town and get a T55 to take the FD off the bike so I could nudge it the last microsmidgen with the shop press.

    All carefully torqued and back together now, but instead of a test ride I'm having a Jim Beam Rye. I've been shade tree wrenching on Beemers for nearly forty years, but I still need to learn to breathe more and cuss less.....

    Can't complain though, total cost about zero, unless I count the white knuckle snow and ice schuss over to Medford yesterday.

    So the reason for the quote of 1100 pounds was that they thought the new part would not fit on the 04 final drive.

    Is that the new unit - doesn't look steel but looks cast to me - the old one was billet machined....

    Steel can be cast. Even believe it or not, iron. I'm surprised that BMW would invest the huge amount of capitol in a fictional process like "billet machining". Billet is a noun, not an adjective. It is a reference to the form in which the raw material is presented. You can buy a billet of aluminum in any alloy you want. It isn't some super exotic high strength form. Wood comes in billets. The correct usage would be "It was machined from a billet of XXXX alloy aluminum".

    That's exactly what I thought too. Looks like a mega-cheap-assed aluminum casting. I guess it must be steel painted silver, but there's no doubt it's a sand-cast part.

    So it's considerably heaver weight-wise than the original and a magnet will stick to it?

    Also, the threads for the wheel bolts look really rough too, but that might just be the lighting.

    No, that is the newest aluminum cast one. In September when I did mine, that is all that was available in the <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:eek:ffice:smarttags" /><st1:country-region><st1:place>US</st1:place></st1:country-region>. :cry

    I'd say Yes. It fit my 05
    You can get part numbers at RealOEM for your bike, according to manufacturing date.

    how reliable is the pricing on that real oem website? compared to some of the parts that i need to fix the damage the thief did they seemed high... that's a different topic.
