Locating the rear wheel

[Allie]

Have you put this one back in the LHS? It sits between those paddle thingys slip right into the rubber damper doohicky. Other wise if ure reinstalling same wheel isnt much difference. But i had someone have the brake bracket reversed somehow on one problem.

If that's the one with the taper facing in then yes I left that on the shaft the whole time (between the paddle thingys). Maybe something will occur to me after I sleep on it. I work tomorrow morning but I think I'm going to pull the wheel off and take a 'sploded pic of everything.

It seems so simple. The rotor position on the hub remains constant. The spacer width between the rh bearing and the brake carrier is a constant. The caliper position in relation to the rotor is determined wholly by the relative position of the carrier which is determined as far as I can see entirely by the width of that top hat spacer. The only thing that could possibly be variable is the bearing position in the hub... Is there any way they could have messed that up at the shop? Pushing it into the hub too far would decrease the distance between the carrier and the rotor but I would not think it possible to do that to the bearing. Am I mistaken in my assumption that the rotor should ride more or less in the middle of the access window for the pads when the caliper is properly mounted?

With any luck I'm doing something really simple wrong. That would be a lot easier to correct than magic grits. I may have to take some pics and measurements. It's the same setup as the 1000 though, the parts diagrams are eye-dentical.

Well heck Allie, I'm not sure what you have going on. In my situation, I was mounting a spoked 750 hub on my 1000. I had to space the brake rotor out .200 Maybe you have a inner spacer problem, I don't know. I'm sure Steve or someone more knowledgeable than me will come along. Good luck👍

Holy resurrection Batman! Was this issue ever solved? I just had pretty much the same thing happen to me with two differences - I did not change anything on the sprocket side and tightening the axle nut is what causes the rotor to drag.

I took the rear wheel off yesterday to have a tire mounted. When I took the axle out of the wheel I left the sprocket side together - nothing was changed. When I put it back together those paddle thingys slip right into the rubber damper doohicky. Everything seems fine on that side. The order of spacers is correct on the brake side. The top hat sits agin' the bearing, next sits the brake carrier correct orientation - there's really no way to get that backward and fit the caliper on. Next comes the plain spacer, then the adjuster, then the washer, then the nut.

With the caliper off I can adjust the chain and tighten the axle nut and everything is fine, no binding of any kind. With the caliper installed over the disc and onto the carrier the disc does not ride in the center of the brake window, it's right up against the outside edge of it. With the pistons fully retracted the pads can be slid in but the outer pad is tight and drags. Tightening the axle nut properly causes quite a bit of drag.

I've had my rear wheel off numerous times and never experienced this issue. I can't for the life of me understand what could have changed between yesterday and today to cause it. Am I making a rookie mistake 15 years in or did they throw magic grits into my wheel at the shop when I had the tire mounted?

Your Truly,

Send me what ure swing arm gap is (if original steel arm), where the wheel sits. and ill do a drawing using spacers/bearings that are original sizes. give everyone else a idea as well. And is ure spoke wheel laced correctly. what size rim are you running and what is the off-set using the disc mating surface and edge of rim. Thanks

Thanks for the reply Sharpy. I think I need the 5mm brake rotor spacer. Spacing the rear sprocket to line up with the counter shaft sprocket is not allowing the wheel to sit center of the motorcycle. Everything has to go .200 to the left. When everything said and done, I'll post exactly what spacers are needed and what I've done.

Just as the drawing says. The center spacer is different. (most measurements are from online part diagrams) But on some bikes theres a 5mm spacer behind the brake disc. I have spoke wheels but also have a aftermarket swing arm so mine does not use it. That's a drawing below to show you what i am referring too. So as long as ure spacers are same left to right you mite need or not need that 5mm spacer. I know the alloy arms are 260mm gap. not sure what the steel arms are sorry.

Will this help or just confuse. If all ure spacers are the same u have a failed bearing somewhere. and since you didnt take my advice about checking those sprocket bolts seating correctly you HAVE NOT check the whole wheel.

Sharpy, I was hoping you could help me out. In your drawing it shows the center spacer 88mm for the "E" wheel and 82.75 for the spoked hub. I was wondering what spacer would have to be wider to make up the 5.25mm difference? I'm thinking it would have to be made up on the sprocket side to keep the brake caliper centered on the rotor. Any information on this would be helpful. Thanks

The rear wheel is located right behind the drivers seat.


Sorry read the title and couldn't resist . Good luck on your endeavors

Thought we rode bikes and you drove cars, And i would say the wheel in under the seat mostly.

Hey sharpy, the only thing that doesn't look right on your drawing is the left side spacer sits into the hub about half inch (most of the first lip of the spacer, which you can see in the picture above too)

I checked my right side clearances, and I'm around 37mm from inside the caliper mount to the adjustment bracket (your drawing says 36mm).

Left hand spacer disappears into a seal and the bearing is recessed.. Baring the 24mm one (brake bracket) all the rest are bearings and spacers. Ill double check about the 24mm measurement. Ok now im just showing off.......

Excellent drawing Sharpy! I downloaded it for future reference ��

Thanks. Its a 80 GS1000ST rear set up, hence the added specs for a E wheel. FYI. Alloy GSX swingarms are 260 wide. Stay tuned
