You're not the only one. Quadz is working on it. Got the issue with the "Thumbs Up" resolved. Something defiantly got boogered up. lol

Quick technical thing or two: bushings aren't supposed to turn. Things turn inside of bushings, but bushings are not supposed to turn themselves. That's like having a spun bearing, which means where the bearing is supposed to be seated, it is loose enough for the whole bearing to turn. You aren't having this happen.
If it turns by design, then it is a collar that takes up the space between the proper bushing and the axle. If that's the case, you can either remove the actual bushing and get proper, full-sized ones machined up, or you can get proper sized collars machined up. If it's collars spinning in the swingarm, effectively there aren't bushings then, and swingarm travel would effectively be destroying the swingarm. I highly doubt there wasn't any bushing. You also keep saying the bushings failed. They did not fail, they were incorrectly sized, which is a failure of either engineering at the factory, or assembly. Precision in fitting things together is important, but so is precision of language. Also, you don't need to separately grease the bushings. Greasing the axle is sufficient, when everything properly fits together. |

i believe in this case the reference column should be free to move which is around the axle and is surrounded by the bushings on the ends and the swing arm in the middle section. i dont believe the bushings (if i understand it correctly) were the incorrect size but rather the swing arm axle and the reference column were not fit properly... which i am hypothesizing caused repeated percussion between the axle and reference column and much of that kinetic energy was transferred to the bushings. One of the bushing didn't allow the reference column to move at all and one would allow it to but only about as smooth as crunchy peanut butter. i did not know that the bushings themselves were stationary.

Hey, so I meant to respond to this, but I forgot, sorry. The 'reference column' would also be called a collar, or a spacer, generally. It's not designed to rotate. It's to keep the bushings in the proper positions (to keep them from moving too far inward), and to keep from distorting the swingarm when tightening the pivot bolt. The pivot bolt is the only part of the swingarm pivot that is actually supposed to move. That is to say, the swingarm is pivoting on the bolt, the bushings and collar don't really rotate per se, inasmuch as they are supposed to maintain a fixed position in relation to the swingarm.
It's the same for the wheels, there's a collar that goes in between the bearings to keep the bearings at the proper distance, preventing fork stiction in the front, and bending the swingarm in the rear. The bushing diameter was too large, that is the problem. It has nothing to do with the collar or pivot bolt. The bushings weren't wallowed out by the bolt, trust me, they were simply too big. |
