Ok so i put front wheel bearings in my 600 this past weekend and I noticed the old bearings were nasty and I can tell water has been getting to them so I started looking and there are grooves in the axel and the little peice on the back of the hub which I suspected but then I noticed the parts breakdown list a collar part# 90387-281V8-00 and also an oring part# 93210-26662-00 . I have never seen these parts on my bike and so I guess my question is where do they go exactly . I have spent time looking at the hub and I haven't seen anywhere for them to go. Help me, what am I missing

If I remember correctly, the collar and o-ring goes on the axle splines before you install the hub. It is common to see these parts missing.
Additionally, if I remember correctly, only the 1998 model had the collar. The 1999-2001 models used different hubs which didn't require the collar.

FYI
Your going to see water and crap in your old bearings when replacing them. That's why your replacing them. Once the bearings have slight play, the axle seals can no longer seal and you'll get water entry. Then the bearing destroys itself and develops enough play that you notice it and have to replace them.

The grooves are common to see on older, higher mileage machines. They do allow water/dirt to pass, and lead to "premature" bearing failure. Sometimes you can use a product called "speedy sleeve" to remove the grooves, but it's a hard product to find in the correct size, and it doesn't work in all areas. You can replace the axles and hub to remove the grooves ($$$), but in time the grooves will come back. These things are used in mud/dirt/etc....like a grinding compound.
Your best bet is to install high quality sealed bearings. Do not rely on the factory axle and hub seals. This way when water/dirt does eventually get past the axle seals, the bearing seals will keep it out of the bearing just a little longer and you'll get more life out of your bearings.

OK well, all that makes sense and is what I was thinking as well. Thanks for the info on placement of the oring, I think I need to run the VIN # to make sure its a 98 because I have been going off what the seller said it was but I'm thinking it's a 99 only because you are right after 98 the did do away with the collar. Thanks again for the clarification!

Do you think it would help to fill the space between the seal and bearing with grease?

Not going to hurt anything if you want to fill it grease. I always grease the splines anyway.

Does your have steel floorboards or aluminum? 1998 had steel. All others had aluminum.
1998 had a welded on hitch to the rear axle tube. All others had a bolted on hitch mount.
The 1998 front rack was bigger. It had 2 "D" shapes on the left and right rear of the front rack. 1998 also had taller vertical stacks on the front bumper.

Post a picture of your bike and I can tell you if you have a 98 or a 99-01 model.

It's definitely a 98 then all steel and heavy! I may give the grease a try and see if it extends the life on the bearings. I put the cheapest bearings I could find in it so I'm sure they will need all the help they can get. dezz, also since you seem pretty knowledgeable about the 600's could a front axle cause it to jerk or pull slightly at low speeds? Mainly if I'm make a very slight right turn I can feel something causing a jerking to the left feeling. The axles don't look bad but are the originals I believe

A bad axle can cause a slight jerk or pull. But so can bad wheel bearings, sticky brakes or wheel alignment. Even the terrain your riding on can effect steering.

You can rule out the axle by swapping them left and right. Both front axles on the 600 are the same, so you swap them and see if the tugging changes.

Thanks again dezz, I'll give it a try and see what happens:grin2:
