Today after talking to a few ... made the decision to put the PM wheels on my M2, and the stock black rims on the S1 .. everything went smooth for the S1 .. bike rolls smoother (PM front needed bearings)and the front PM wheel with the new bearings went smoothly .. the rear PM moving to the M2 is where the problem lies .. The carrier for the brake caliper is rubbing on the lip (where the rotor slips over) and is preventing the wheel from spinning, and it actually was bad enough to cause some shavings to appear. The bearings are good, but it seems that the bearing is in too far, but how is that possible ? The questions that come up, the PM wheels came off a 97 - which has different brakes, which means different carrier for the caliper than my 99 .. spacers are all the same though .. the only difference I had was in the front with the speedo cable. So I am without a clue .. is there something I am missing - do I need a different carrier ? do I need the Brembo rear brake setup to make this work ? Any help would be appreciated as my M2 is down until I figure this out. Thanks Brian | ||

Here are pics to help show what I am talking about. First pic is of the carrier positioned on the rotor ... the next two will show where the problem is ..  Here is a pic of the hub of the wheel, if you look at the raised lip - you can see its a bit roughed up - that is from the carrier - which is supposed to sit flush with the bearing face.  This pic shows the inside edge that is supposed to sit flush with the bearing, it obviously isn't since the lip on the hub is rubbing on the carrier - see the roughed up arc on the carrier (shiny rub marks between 'Nissin' and the hole)  Hopefully that will help you to see what's going on and hopefully tell me what the fix is .. | ||

Well,the early bikes had Brembo brakes and I'll bet there is a difference in carriers. | ||

Tattoo, There was a post some months earlier that listed the difference between the pre-99 PM wheels and the later PM wheels. There was a difference of 0.1" in the hub section of the wheel with the earlier ones being wider than the later versions (if memory serves me). if I locate the data I will post for you. Good luck, Boiler | ||

Firemanjim - I know they have different brakes .. and yes - the carriers are different .. Zenfrogmaster sent me a PM letting me know that he did the swap to a 2001 model using the older PM style and had no issues. Buellboiler - that sounds feasible .. I did a search in the archives and didn't really find anything useful , if you can find it that would be great It was also brought up that the rear bearings might not be the right ones also leading to this problem... What sucks is that neither the parts or service manual address the PM wheels or any difference in mounting the two. | ||

I had a friend run into the same problem, he just went to the hardware store and bought a few shims. everything worked fine. | ||

I thought about shimming it, but then the part of the carrier that hooks the outside edge of the rotor may rub, or come a little closer than I'd care for it to. I think at this point it might be easier to just shave a little material off of the lip on the wheel .. it appears to only serve as a guide for the rear brake, so as long as I leave enough to hold the rotor in place I should be fine .. it needs to be smoothed out anyway since it got chewed up by the carrier when I test rode it after assembly .. Still be curious to know what the difference exactly is, then I would know exactly how much can be safely removed. | ||

The fix is simple and I have had this problem. All you have to do is take a flat file and file off the bearing hub by .1 inch as I recall. The data is posted on a previous post in the knowledge vault in wheels. | ||

Thanks S3thunder... and everyone else who had some input .. I looked for info in the KV before I posted, but maybe didn't search with the right keywords ... I am going to have it machined off tonight so it's for sure an even amount all the way around... I'll post once done and back on the bike hopefully declaring success. |
