First and foremost, want to thank Mrmatt for his post a while back that make me decide to do this for my project. Here's the link to his thread. Now that I am finally getting around to doing it, I can verify all the measurements he took. Lots of the pictures are just of measurements, but this way it can't be questioned in the future. *** Not finished yet. Still need to take measurements with the wheel on to get final info. Forewarning, you are going to need either a very large snap-ring plier, or you will need to modify a pair of needle nose pliers to get the snap ring off the eccentric. This is the hardest part of the disassembly. Snap ring pliers this size are $35-$50. Otherwise you can grind down the tips of the HF 90 degree needle nose pliers with the orange grips. The VFR ring is fairly easy. The triumph one is a dog. So lets begin. First things first. Injure yourself in such a way to make tool handling painful and difficult. As a side note, rags are not sufficient protection against 20ft long chips. - Next, find yourself a comfortable environment. 88F and 70% humidity will do nicely. Then find the mess that someone has left behind at your work area, and clean it up. - Wiped down and chip free surface. Grabbed some blocks, clamped the swingarm down, and got to taking measurements. - Measurement for inside of sprocket carrier for VFR - VFR sprocket carrier thickness. - VFR sprocket carrier surface to surface double check. - VFR swingarm surface to wheel mounting surface. - VFR wheel mounting surface thickness. - The hammer lies upon its prey. Triumph eccentric tapped out and removed. It came out nice and easy. I couldn't get the caliper hanger off, so I had to use the hammer to give it a couple of light taps to get it started. Once the caliper hanger was on the step, it came right off, so must have just been a little dirt keeping it from coming off. - So nice of triumph to add never-seize. Probably helped with the removal. - Either Honda didn't bother putting any grease on the eccentric, or it all dried up and washed away. The honda eccentric was pretty difficult to get out. Had to use the mallet to get it to the caliper hanger, but the eccentric kept getting stuck part of the way out. Turns out that there was so much dirt and debris in there that it would get stuck between the middle of the eccentric and the swingarm and bind everything. Took lots of shaking and blowing junk out to finally get it out. - Total height of the triumph eccentric - Triumph eccentric swingarm section. - VFR eccentric total height. - VFR eccentric swingarm section. - Just for giggles. Triumph eccentric weight. - Honda eccentric weight. - The VFR swingarm after removing the eccentric. You can see that the surfaces aren't very clean, and there's still some dirt in there. - Time to toss the Triumph goodies in there. Fresh new coat of never-seize on the triumph eccentric - Sitting nice and flush - Nice and flush on this end too - Somehow I feel like I have just made it heavier. Also, you need to use the triumph caliper bracket to have the eccentric sitting where it is supposed to. The VFR caliper bracket has the same ID, so if you really wanted to use the VFR hangar for whatever reason, you could possibly make a spacer for it. - Triumph rotor carrier thickness. - Thickness of sprocket carrier for triumph bit. - Triumph wheel mounting surface to swingarm surface - Triumph sprocket carrier surface to swingarm surface - VFR Wheel offset 848 Wheel Offset Weights are added to the chart. I don't think anyone wants pictures of all that. You can go in the photobucket album if you really want. So here's a chart of the differences in sizes and some weights End result is that I gain 0.5 lbs by doing the swap for the opportunity to run a single nut wheel. I have a VFR wheel with a tire and the 848 without, and still have to consider the caliper, caliper hanger, and the rotor, and the wheel nuts, so that's not the total weight just yet. Looks like everything is still pretty close to where it should be, unless someone finds a fault in my math and measurements.
