The odyssey begins !

This is the thingy the drive shaft hooks to. It has a bearing on each end. Both bearings came apart and turned into shrapnel !

Some of you wizards help me understand this torsion spring thing. Does it twist (I don't think so) or just compress and de-compress as the swing arm travels up and down?
 
I know where the shaft is and all that but I don't see the shaft when I take my tire off. I put a little grease where the wheel hub goes in the bevel box and that's it. Are you taking the bevel box loose during a tire change? I have a 2010 Roadster and one other member has one. He said the bikes drive shaft had some type of blue grease on it's splines. I'm hoping Triumph has remedied this situation.

Fred, if this makes you feel better, looks like the Spyder will be covered by the insurance but sadly the mechanic say they may total it since that engine is just shy of $10,000 :eek::eek::eek::eek:

The torsional damper's purpose is to absorb some of the shock between the engine and the drive train. Like when wacking the throttle open or downshifting hard. If the pictured gear tries to turn much faster or slower than the shaft it rides on (which connects to the drive shaft) it causes the ramp mechanism to compress the spring which absorbs some of the energy. It takes some of the shock away from the gears / splines much like a fishing pole keeps the line from braking. The swing arm movement is accommodated by the rear driveshaft spline sliding in an out of the final drive. That's why the moly lube is so important.

Harley uses a similar device only their mounts on the end of the crank.

You should remove the bevel box at each tire change or no more than 10,000 miles if you run a darkside. When you pull it loose from the swing arm you can the see the end of the drive shaft up in the swingarm tube. THAT is the spline that really needs the moly grease. I use the Honda moly grease, you can buy it on eat-me-bay. When you reassemble leave the four bolts that hold the bevel box slightly loose until you tighten the axle. Then tighten them. That makes sure the bevel box is aligned properly and not stressing the rear wheel bearings.

Took her out for the maiden voyage this morning, went a hundred (you didn't think I was going to start babying it). Everything held together ! I'm now wondering if that inner bearing knocked the clip off and slid over some time ago as it seems to have noticeably less drive line slop now. Plan to put a hundred or so miles on it than pull the pan again and clean the screens of any remaining skita. For the moment the odyssey seems to have ended on a happy note. Here she is all buttoned up
