wheel bearing question

[fullercameron]

Wondering if any of the gurus can tell me if there is a way to visually check what year my front wheel is. I have a 72 XS2 and a while back I realized that my wheel is not a 72. The wheel doesn't have the strange one-year floating rotor from the XS2, but I am not entirely sure which year the wheel came from.

I am looking to replace the front wheel bearings and from what I can tell from various parts manuals, early year hubs used 3 bearings while the later style used only 2. Mike's sells a bearing set w/ the seals but I would like to make sure that if I need the third bearing, I get everything all at once.

Not trying to be lazy, I know I could just go out and take the wheel off but I am hoping to avoid it so I'll be able to make the short ride to work and back until I get the replacements. I'd really be grateful if someone has the info.

Also, I was going to call the local bearing supplier tomorrow and see if I could get the 6303-RS bearings locally. Is there any reason that I shouldn't use what I can get here? and if so, if I am careful about removal, should I be able to re-use the grease seals and save my self an online order?

Thanks again.

Only thing I can comment on is sourcing the bearings. You will likely be better off buying locally. Get quality bearings - not Chinese.

The grease seals perform very little function if you're using bearings that are sealed on both sides. Basically they're cosmetic. So reuse them.

A trick for pulling the old bearings - expanding concrete anchor bolts. Slip one into the bearing, expand it and it grabs the inner race. Then drive it out from the other side. Easier than trying to move the inner spacer and find 1/32" of the inner race to tap on.

Nice, very clever!!

The wheel bearing crosses to about a bazillion yamahas.
I think 72 is the only year that had a third (rotor) bearing.

Yes, get them locally. Get the "2RS" ones though. They will have the rubber seal on both sides. The "RS" type only has a seal on one side and is open on the other. Don't get the "Z" or "ZZ" type, those are steel seals. You will find those on some of the early wheels. Everybody uses the "RS" rubber seal type for replacements.

If your disc is bolted directly to the hub and not that "floating" carrier set-up, then you only need two bearings.
