ZOOKA,
Mark my words, - this is what happened.
The two metal ears on the "Speedo drive ring" broke off. The loose metal fragments undoubtedly tore & ripped apart the rubber seal on your left hand wheel bearing (I just did this), and the other seal that goes over that. So, since I'm going through this right now, I know the parts you need. They are,
1. Speedometer Drive (That'll set you back $126)
2. Speedometer Drive ring
3. Left-hand bearing seal
4. Left-hand wheel bearing (the rubber seal on the side of your old one is now torn)
With mine, I replaced both wheel bearings even though my right one is still perfect. I still have that right one, - and it is as smooth as silk. I'll give it to you if you want it. But all the other parts you'll need to order.
BTW, if you bought you Triumph less than 2 years ago, this is a warranty issue and I'd b!tch if I was you. Mine was just outside of the warranty.
If you need the part#'s, let me know.
All the best,
-BT
