A few months ago there was a thread about an alternative alternator belt to the BMW brand (Napa #040233). Anticipating the upcoming change I purchased the Napa belt ($12). Well I am here to report the Napa belt was too large. It slipped right onto each pulley which is not a good thing. Napa offered a shorter belt by 3/4" (Gates part #K040225, Napa #25-040225) which I believe would fit but unfortunately they did not have it in stock so I ended up buying the OEM belt for $30. cry I tried to match the belt at two Auto Parts stores but could not find a match. One alternative looked pretty cheesy and low quality. So if anyone is in need of a new belt I would love to know if the Napa belt 040225 is the same size as the BMW belt.

A quick look at the parts fiche shows the belt for your bike as 12317690571 (4pk582),, I believe that is a 582mm belt..

If you look in the archives here it shows the --NAPA part # 040233,as 9/16" x 24-3/8" 14mm x 620mm..

That is 38mm difference..

If that info is correct then no wonder the NAPA belt didnít fit..

Canít seem to find the belt length on the NAPA 040225 belt but a quick call to your NAPA dealer should give you info on itís length..

What was the part number on the belt your removed as that should point you to the correct length belt needed..

Twisty

Answer to your question: 12317690571 (4pk582),, I believe that is a 582mm belt.

I simply used the Napa part number that was supplied in the earlier post when I purchased the belt (Gates belt actually). I had no idea the length of the belt.

Considering the difficulty you are having finding the correct part to fit, I think the smart thing to do in this case is just to use the OEM part.. The money you are saving in a third party part is not worth the risk..

It isn't something that needs to be replaced all the time and even if you are talking about 20.00, if the aftermarket part wears prematurely or breaks, the inconvenience would be worth significantly more then that, right?

You can buy the part from Chicago BMW and get 20% off.

+1 !!! Every time one of these threads appears I continue to be amazed at the lengths some folks will go through to save $10 or $20 on a part. Be it an oil filter or alternator belt or any other item. It is REALLY worth it? We are talking about a $20,000 motorcycle and in most cases the owners pride and joy! Consider the issues one may face if that aftermarket part failed ... warranty issues, getting stuck on the side of the road, other damage to the bike, etc. Hey ... I am ALL about saving a buck and am actually known to be Mr. Frugal (cheap) but some things just do not make sense to me. I say....... just order the $25 belt from Chicago BMW and save the $5 someplace else ... like on a farkle.

The main reason for the alternative belt search was convenience. It is a 1 mile round trip to Napa vs. 40 miles round trip to the local dealer and this is on L.A. freeways which can be a major PITA.

If we can verify that the substitute belt listed in the parts data sticky is indeed wrong, let me know and I'll remove the info.

If you order it from Chicago BMW, it will come to you !!!!! You can also have the dealer ship it to you !!!! Or drive during less busy traffic at 2:00 pm in the afternoon. Even if you did have to travel in traffic, it sure is better then getting stranded somewhere on the road with the wrong part...

You have other options that I believe are healthier for you and your bike...

Nothing personal, but I would sit back, take a breath and think about it!!!

No worries RG. I took a breath and replaced the belt 2 days ago with OEM. Thanks.
