Has anyone found an after market bearing for the 2000 AC 500? Does anyone have the measurements for the bearings and seals? If, not where is the cheapest place to buy AC bearings?

 

Should be numbers on the bearings and you can get them at your local bearing retailer. The only way it works different is if the manufacture orders a special bearing and pays extra to keep them from making it for others, this is very rare anymore. The manufacture will tell you the are special or a matched set, but it is usually a lie. They put special prefixes and suffixes on the numbers if they are special. I had a racing buddy who worked at a bearing wholesaler and he always got me the right bearings for less than half the manufactures sold them for. When I was still working in the marine industry I found this to be true of the major outboard and I/O manufactures.

I haven't disassembled it yet, so if someone has the part number for the bearings or the measurements of the bearings I would appreciate it. thanks, Rob

 

Rob,

I have never had the bearings out of one, but AC's part number will not be the same as the bearing number. Looking at the pic in the AC parts catalog and service manual it looks like a fairly standard ball bearing or a roller bear that they sell as a set. I would bet it's a ball bearing as that's all that would be needed, but then again I didn't design it. If it was me I'd pull it apart an look, bearings are pretty standard anymore.

Ditto with Bear. I was going through some GM alternators and other accessories a little while ago. First time out I went to a local AC Delco dealer for the bearings. I recall one particular one, the front bearing for a CS-144 alternator. The "Delco" unit was like $12. Shortly after that I discovered the local bearing dealer. I went in with the same bearing (another alt). The guy recognized it from accros the counter, he did not even pick it up. Walked back and got one. $3.50 + tax.

I would locate a local bearing dealer, take it apart, then take them the bearing.

On that note!! I heard a littla about bearing in some A/C's when I was shopping them. I would bet they do as described, they use over the counter bearings. That way they tailer their surrounding parts to fit thus only having to having to fabricate parts and not all of a given system. If they are prone to fail, and use a standard bearing, I wonder if there is not a shorcomming someplace else that makes the bearing fail.

Any way, good luck.

How can you tell if the wheel bearing is bad does it start making noise or does it have play? Also I have not seen any one list a bearing number yet for the AC 500 has anyone used a different bearing than arctic has if so posting the part number would be helpfull.

 

The wheel bearings that Arctic Cat sales retail for $33.95ea. The reason bearings go out is dirt/sand tearing the inner seal and then water rusts them. The people buying bearings all the time normally don't wash the machine(or if they do, they don't spray out where the axle meets the knuckle).
The bearing is not common, it has a wider inner race and a narrower outer race. Changing the bearings can be difficult if they are really rusted. Remember to replace both seals (sold separately). These bearings can be serviced if you have ample time to do maintance.

Bob2003, bearings make some noise, but most of the time the wheel has excessive movement when you grab the top of the tire and shake it in and out.

 

Rob, try this link, they have a listing for AC's, and not a bad price for the whole front or rear kits.

Arctic375, not necessarily. I just had a brake pad failure on the right front, the pads came unglued from the backing and the inner one disappeared. Anyway while I had the wheel off I tested the bearing with my stethoscope and it was noisy and a little rough, nice and tight, but rough like it would have had a rumble in it if you could have heard it. Replaced the pads on the left also and the bearings were nice tight and smooth. Pulled the right ones and they were rough for sure, couldn't see any rust, just rough. You could feel the with the wheel on too.

 

Thanks for the web site. Does anyone have any good tips or instruction on replacing the wheel bearings in the AC 500I FIS. Do you need a press to get them out.

Thanks..Bob 500I
