Bearing Part #

[Matt]

Does anyone happen to have the part number for the 6205-size bearing that has a rounded outer ring? The type that sandwiches between a pair of plates for a jackshaft. I believe the one I need also needs one side open, the other sealed.

Matt..Usually that number is all you need..Your local bearing company will have these,Just ask for 1 inch radius bearing.. It is 1"x52x27.. I believe every parts book will have there own version of a number..

Matt....I'm a little confused as to the type of bearing you are looking for. The 6205 you mention is commonly used in idler wheels and has squared edges with a 25mm ID. If you are looking for the same type of bearing with rounded corners, I know they exist, but the number doesn't readily come to mind. But if you are looking for the rounded corner locking collar type of beaing with a 1" ID, I believe the number is 1736205-100 (if that's wrong, then it must be 1726205-100). It'll have seals on both sides, but you can easily remove one seal.

Sorry about the confusion. Here is the story:
I'm still working on my XLT. It needs new driveshaft/jackshaft/chaincase bearings. The chaincase uses the same 25x52 bearing the idler wheels use, but without the seals. So I ordered 4 of them - not realizing that they don't work on the other side of the sled - where the bearing is sandwitched between a pair of plates. So it is the right size, but the square edges don't work. So I was hoping for a number so I can order the correct ones.

I'm not sure what year your XLT is, But I believe all XLT's used a standard 1" locking collar type bearing on the LH side of the jackshaft. On certain years, it was a conventional locking collar type with a seperate locking collar. Some of the later ones I think had the locking collar built into the bearing and it used two set screws....and some of the very last ones may have had a press fit non locking collar bearing (but I think those were used only on the driveshaft). In either case, I'm sure you'll find that the 6205 chaincase side bearings are too small to fit the LH side of the shaft as they are 25 mm inside and the LH side of the shaft is 1" (darn close to 25mm, but just a smidgeon larger). You can pick up a good quality 1" locking collar bearing from a John Deere dealer (or any farm equipment dealership) and I'm sure you'll find it much cheaper compared to buying one at a Polaris shop. Also, I don't think any of the bearings used on the LH side (jackshaft or driveshaft) were open on one side as you stated in your original post.

Unforunatly I don't have a Polaris dealer nearby (or any snowmobile dealer within 45 minutes), otherwise I would just go and have them look up the correct parts and have them order it. It didn't dawn on me that the locking collar could be part of the bearing - my tech manual doesen't clarify that. I have a good auto parts store nearby that will get me whatever I need in a day if I can give him something to reference. Neither of the bearings from the sled are good enough to compare (one blew apart, the other, I have not been able to remove from the shaft).

There is a grease zerk on the speedo drive housing and the jackshaft plate - I assumed these were to grease the bearings - which is why I assumed they should be open on at least one side. But as they say, assumptions are the root of all screw-ups.

Matt these bearingss are very common.
Any auto parts or farm store would have them in stock.
And you can pop out a side seal with an o-ring pick if you want it greaseable.

[Matt]

OK, so I need a 1" locking collar bearing - is there a term for the rounded outer ring or is that assumed since it is locking collar?

As far as the grease getting to the bearings, you could as you say...use a bearing with a seal removed, on the speedo angle drive side of the drive shaft. But if you look closely at your jackshaft bearing mounting flange, it too is designed to be greased. However, it is not equipped with a grease zerk, but rather a tiny hole which is meant to be greased with a grease injector needle. Since not many people have an injector needle, this is seldom done. Obviously you could not use a bearing with a seal removed on the upper bearing flange or grease would just come out (if you could manage to get it in there). Polaris used greasable bearings in these locations. The bearings have a very tiny hole on the outer circumference to allow grease to enter the bearing. Some of the bearings also had a groove machined all the way around the bearing like this used one in the pic. And some just had the hole without the groove. So when you go to order the bearing, just specify that you want a standard 1" greasable bearing and you should get one with the grease hole. The bearing in the pic is an old one from an Indy 500....it is stamped NSK 205-100. Different manufacturers use different numbering systems, so no big deal if the one he orders you is a different number.

It is called a radiused bearing Matt.

[JDT]

Ag guys may call it a pillow block bearing also.

If you would like the Polaris number,it is #3514518


Frankie (I have micro fiche for all Arctic Cat-Polaris sleds 70's to present if anyone needs a number for something)

I finally got the right ones - thank you all for the help.

One more question - I put the drive shaft back together with the bearing plates on the outside of the tunnel, but it doesn't look right. The drive shaft comes maybe half-way through the bearing. This is how it is pictured in my tech manual, but I think the plates should be on the inside of the tunnel. Am I right or is it supposed to be like this? The drive shaft is positioned correctly on the chain case side. I didn't reinstall the speedometer drive because it is shot. Again, the sled is a '95 XLT Special.

[JDT]

You need to move them inside Matt.

Usually the shaft end will be flush with the bearing edge.
