Wheel bearing help

[lidirtrider]

I was installing, or about to install the front wheel bearings today, and ran into an issue. I got bearing and seal installed on the disc side of the wheel. When I went to install the bearing on the speedo drive side, it seemed like the spacer tube that sits inside the hub, between the 2 bearings is too long. There is a lip in the hub that I assume is where the outer race of the bearing sits, and when I put the spacer in place, it sits about 6mm higher than the lip. If I install the bearing so it sits tight to the spacer, it will sit too high for the speedo drive ring and washer to catch the cutouts in the hub.

Has anyone else run into this problem? Can that spacer just be cut to right length, or is there something I'm missing?

I'm using the All Balls Racing kit and had no issues with rear wheel.

Is the spacer crooked? or out of position. Sometimes they take some finagling

No its definitely not crooked. The spacer I'm talking about is number 10 in this diagram.http://www.yamaha-motor.com/partviewer/default.aspx?ls=sport#/Yamaha/XS650B_-_1975/FRONT_WHEEL_TX650A_-_XS650B_-_C/XS650B_(1975_MOTORCYCLE)/FRONT_WHEEL_TX650A_-_XS650B_-_C_(XS650B_-_1975)

There should be a lip or step in each side of the hub to stop the bearings from going in too far. Even if the new bearings were wrong (as in too thick), that still shouldn't affect that spacer. The bearings would just stick out too much.

5twins, I may not have explained clearly. I see the lip/step in the hub where the bearing should sit. The problem is that the spacer is so long that the bearing wont go in all the way to that lip. The spacer sits about 4mm higher than the lip. If I push bearing against the spacer there would be a space between the brearing race and that lip/step, and the speedo drive plate would not engage the cutouts in the hub.

I measeured evrything on both sides of the hub and the bearings, and the bearing on the disc side is installed right where it should be. Does that sleeve sit in the inner races of the stock bearings? If that is the case, can I just cut the spacer to the correct lentgh?

wrong spacer? didn't put the front one in the rear wheel did you?

HAH! I actually thought about that. I was smart enough tho, this time, to keep all of the parts seperate, and in order of removal. I also took the wheels apart on different days. I reassembeld the rear wheel already, and everything lined up perfectly, so I'm pretty sure thats not the case.

good man, well the spacer can't magicilly grow so measure inside the wheel between the lip/step (which would be the distance between the bearing inner races) and the spacer, spacer should be slightly smaller to allow clearance

Well, I decided to just go for it and press the other bearing in and see what happens. I kept an eye it as it went in, and went deep enough so the speedo drive parts would catch the little cutouts in the hub. As it all went in it pushed the bearing on the other side of the hub outwards a bit, but it all seems to be right within spec, so I guess I was just splitting hairs the whole time.
