sprocket bolts rubbing on swingarm. urgent help needed

[wayno]

I've reassembled the back wheel in the bike after changing the chain and sprockets, now the top of the rear sprockets bolts/studs are rubbing the weld in the inside of the swingarm??

I've had the back wheel out again but find anything amiss. Anyone had this or have any ideas because as far as I can tell everything looks right, apart from the obvious rubbing

Pic please!

sounds like a spacer in the wrong place.

I've figured it. The centre of the sprocket is recessed, the difference in thickness is causing the heads to stand proud and rub. Supposed to be a did kit, yet nothing but problems

I have the same problem. I have just changed to a DID set. But I don't see the sprocket recess being the issue. The sprocket I had before doesn't have the recess and that catches in just the same way. I am desperate for a solution. The guy I bought the bike off resolved the issue by not tightening the back wheel fully - I kid you not. As I look at my back wheel it looks to me as if it needs a bigger space on the left to stop the swinging arm being pulled towards the bolts as you tighten the wheel nut.

I put a series of small spacers behind the sprocket to pull the studs back a bit. As far as not doing up the back wheels goes............ Tell him he's a dickhead.

I can see that being the most logical way forward as it will shorten the distance the swinging arm can be pulled in. Either that or grind the bolts down.

It doesn't reduce the amount the swingarm can be pulled in, it basically moves the studs a couple of mm toward the centerline of the wheel. The same end result as shortening the studs

The washers would need to be between the sprocket and the hub carrier, or between the hub carrier and the wheel which reduces the distance by which the swinging arm can be pulled in. If you put the washers under the nuts it would make no difference at all. Essentially I need to increase the distance between each wheel spacer, otherwise the studs will still hit the weld. The only thing is I imagine it's going to need a fair few. But what I find odd is the non recessed sprocket is no much better. The other option is to trim the studs.

No, they go between item 2 and 9 on the above drawing, everything stays where is is apart from the studs which move in to the recesses further

Right, sorry that's what I meant when I said between the sprocket and the wheel. I take it this is a common issue. thanks for you help.

It's an odd one, several people have used did no problems, others have the problem, I assume it depends on your welds

I am growing more depressed with each passing day. I have put the spacers on and the bolts just miss the swinging arm, by the thickness of a gnats proverbial. Now I find the other problem is that the hub carrier is also rubbing on the inside of the swinging arm. I am going to have to put a spacer on the axle shaft to pack that out as well. I also notice having cleaned the axle shaft off that it is scored as well. I am so hacked off with this bike already.

Not meaning to be insulting but - is the spacer on the rear axle there? Sounds very like something is missing.

Both spacers are there, one either side. There is something definitely not right. The top of the spacer is virtually level with the surface of the carrier if that makes sense. The swinging arm is tightening against the surface of the carrier at the rear end of the carrier, if that makes sense. I can see why that arsehole who had it before hadn't tightened the back wheel.
