    Too much gap assembling eccentric and Cush drive?

    I cleaned everything and started assembly of the Cush drive and eccentric adjuster.
    looking from the rear there is an 1/8” gap between the back of the Cush drive and the eccentric adjuster. I don’t remember any gap before disassemble. I torqued up the stake nut and nothing started to bind but the rear sprocket seems to be too far to the left.
    i think I’ll take it apart again and see if the cush drive was suppose to seat into the eccentric adjuster.
    Any suggestions greatly appreciated!!!

          doesn't look terrible from here either. how are you checking the sprocket alignment?

            I’ve taken it apart 3 times and everything is as it should be. Before I took it apart I’m pretty sure there was no gap between the Cush hub and the eccentric carrier. I figured when I torqued up the big nut that it would pull together. It didn’t. Other than cleaning everything I replaced the Cush rubbers.
            I’ve only eyeballed the sprocket alignment, although it’s looks like the sprocket teeth are a bit to the right on the rollers when viewed from the rear.
            is there suppose to be a small gap between the the eccentric adjuster and the Cush hub?

              I just eyeballed my bike, and that gap is also present:

              As with others here, I don't know if that is exactly per spec, but my bike seems to ride fine like this and I haven't noted undue chain wear or noise as I would expect from misalignment.

                I wonder if the worn cush allowed it to sit in farther than it should have and now it's correct? I'm going to look at mine tonight when I get home and see as they are worn out too. New ones are over in Houlton so will go get them probably tomorrow.

                  There's no way cush rubbers can be responsible for stand off. That would mean as they wear your hardware would be instantly loose. Bearings and collars have to bottom out to be torqued, just like the wheel hub of a standard swingarm machine.

                    You sure?

                      Flange Bearing in the Flange Cover bottoms out on the Driven Flange.

                      And looking at his picture, that's not even the gap he's talking about. Looks like the gap from the BACK of the Driven Flange to the Chain adjuster. If the rubbers didn't allow the Flanges to bottom, there would be separation between the flanges. Sure looks like the Driven Flange is fully recessed into the Flange Cover.

                        That’s exactly what I have. Maybe grease and dirt made it seem like a tighter fit than it was. I did lightly file the side tangs where the eccentric adjuster wrench mushroomed the tangs ever so slightly. I had to buy a larger external snap ring pliers to put the snap ring back on. I’m happy with it now.
                        It has a vector 525 46 tooth rear sprocket. It won’t be my first choice for gearing.

                          I agree after staring at it long enough.
