Quad Rings no problem(old sticky)

[Simon]

Hi, As most of us seem to have a problem with the swinging arm Quad rings rolling when refitting the swinging arm I have started a spreading method to overcome this problem and it works a treat with no component damage and it takes 5 mins.Note I have only tried this on a carbon swinging arm though I intend to try it on an aluminium one soon. First I got an M12X35mm bolt and fitted a plain nut until it was flush with the end of the bolt, fit the bolt between the inside faces of the swinging arm at the front where it starts to angle down (I have pictures of the procedure,I've put them in my gallery,simon) put large penny washers between the face of the swinging arm and the nut and bolt unscrew the nut gently until the inside measurement at the pivots measure 55mm (this takes very little pressure to achive this measurement as the deflection required is only 1-1.5mm), offer up the swinging arm to the frame with the spreader bolt still in place, install the bearings through the bushes and fit the retaining bolt but leave it loose, remove the spreading bolt then tighten the retaining bolt then set up the bushes as normal, job done.Simon.(To aid this information there are photo's in my gallery.Simon.)

That's a good idea. Another solution is to Superglue the Quad Rings to the swingarm. I can install my swingarm in 15 seconds!

Yep one of the first things I tried that but I was unhappy with the result, as the quad rings still have to be forced past the sharp edge of the boss that it seals against tearing the seal or just taking the edge off the seal, thus the seal is no longer doing the job its designed for, also you have to clean off the old glue if you replace the bushes or seals just my opinion though.

Wow!  Good call.  I had a different plan of attack that worked with the older aluminum swingarms(read Proflex 450).  We used  a QR skewer in the rear dropouts and cammed it just enough to spread the pivot.  It worked great, but wasn't worth beans on the newer Evo and Oz swingarms as the cross-member was much broader.
