I just received my R3 back from the dealer.I took it in because i thought the output shaft bearing was going out,However after a teardown it was discovered it was not the output shaft bearing but the next bearing to the rear.The one in the rear case that supports the shaft where the driveshaft slides in.Just wondering if anyone else has had this problem????
NOT! THE OUTPUT SHAFT BEARING

I'm thinking this is the same bearing that went on mine at 11,000 mi. The dealer pointed out that it WAS NOT the output bearing but another one that had been improperly installed at the factory (something he said Triumph was aware of) on some R3's.

Gasket,
I noticed something was wrong at about 10,000 miles when I romped on the throttle one day and I heard what sounded and felt like a gear skipping a tooth, or a chain slipping a tooth or two on a sprocket. That was the beginning of things to come. It only happened at high torque loads, but got worse. Becuase the torsion dampener bearing was going, it was causing slop in the whole drive line, and this was allowing what I consider, another flaw in the transmission to show its ugly head, and that is the 2nd/3rd gear dog gear, I (in my opinion) think that they were made wrong, which causes shifting to second non-perfect, and also, sometimes the gear would disengage depending on what teeth engaged. Since I had more slop, there was even a better chance that I was going to have problems. Anyway, as the bearing got worse, so did the gear skipping. So, I had multiple problems in my tranny. The good news, is that it was all fixed, and the tranny is better than ever now! They replaced the 2/3rd gear dog gear, (along with a bunch of other stuff) with a totally different designed gear, that has more surface area for mating, and also, the difference in the teeth protrusion is not there. I have had no problems shifting to second gear no matter what RPM I am at, and there have not been any false shifts from first to second either. The bike feels great, better than new, and it now has about 13,500 miles on it.

Those are different symptoms than mine had.I had about 18000 miles when it started, I was on a trip to California when I noticed what sounded like a dry wheel bearing going out.It didnt matter what gear I was in or if i had the clutched disengaged.It was directly connected with road speed not engine rpm.

Honker, my experience was like yours - sounded like disc brakes scraping; I even stopped to see if something got caught between the wheel and the frame. No problem with any gears and no relation to engine speed, only road speed. The explanation my dealer got from Triumph was that in some cases a bearing had been installed backward and therefore did not get the lubrication it needed, causing it to fail.
