rear axle/bearing dimensions

Recommended Posts

OK so here is my problem (one of 'em anyways):

Ordered new rear wheel bearings from pivot works. The inner race diameter was larger than what was in my 06 300XC so when I put them in the axle did not contact the bearing, and the dust seal did not contact the end cap. The bearing that was in there was also 2 mm wider than what Pivot works sent. I called pivot works thinking that the kit must have been mislabelled at the factory, and being the nice guys that they are they sent me another kit...same deal!

So the question is: What are the dimensions of the stock axle and end caps? Perhaps a previous owner put a different axle and end caps in?

I am back up and running because the local bearing shop had some in to replace what was in there, but I'm using the old dust seals. I don't want to order OEM stuff just to check it against what I have cuz that isn't cheap.

Thanks all.

Maybe someone could throw a micrometer on the outer spacers where they go into the bearing real quick?

Just an FYI, I have used the MSR bearing and seal kit twice in two different bikes no issues. Kept the stock spacer this time, replaced it with an OEM one last time. The kit costs a little over $20.

the spacers for the newer bikes are stepped to better seal and keep out debris.

battery is dead in my micrometer...argh.

Hey Borlo,

I work for Pivot Work, is it possible you could get the bearing numbers off the Pivot Works bearings? There are aftermarket upgrade kits out for that bike, which are larger and we think that may be the issue. If you can get those numbers, I would be happy to research it further.

That is very odd. I have been using the Pivot Works kits for a long time and never had a problem.

The rear axle is axactly the same between your bke and the bikes I currently have. Also, the bearings and

seals are exactly the same. I can throw a caliper on teh axles and bearings tonight and let you know.

The rear axle has been the same diameter for a very long time.

Thanks Pockets and Joe.

The # on the Pivot Works bearing is 6005 RSC9. The number on the current bearing is 6204 RD. I was able to find a 6204 at the local bearing shop, but am still running the old dust seals.

I did not have time this evening to pull the rear wheel off my bike but I did grab the OEM spacer that came on my bike. Here is the inner and outer diameter of the spacer.

Thanks for those photos Joe. Those spacers look a bit different from mine. Maybe a previous owner switched something out. It looks like that inner lip goes inside the bearing?

This is my first orange bike and it made its way to me used, so...

I'll snap some dimensions in the next few days or post up some photos.

No, I got the bikes we have now new so those are the OEM spacers. The spacer do have a different part number from your bike but the inner and outer diameter MUST be the same because the bearings, hub, and axles are all the same. The Pivot Works bearings, seals, and spacers went in after the first season of use was over. Those Pivot Works spacer also have a little grove for an o-ring, kinda cool design.

So I forgot to post the resolution to this problem. Long story short: Pivot Works rocks. I called and talked to Pockets and it turns out I had the aftermarket upgraded bearings in my bike. They didn't have any sets in stock, so he sent me all the individual parts: bearings, dust seals, and even a new spacer and end caps!

That is the kind of customer service that will have me buying their products for whatever application I'll need in the future and recommending them to anybody. Next up: shock bearings.
