torsion dampener

Hey all my 05 rckt is making a terrible grinding noise coming from the left side of the engine, it only happens when I take off and start to accelerate. I'll let off the throttle when I hear it, it goes away immediately and then I can continue on through the gears up to cruising speed with no noise. im thinking its the torsion dampener bearing... any thoughts.

I wish I had some solid insight for you. I am a bit of a novice myself mechanically. I do know a friend had to have that bearing replaced on his '05. Seemed like a big job, but I have had the front cover off of mine to check the detent spring and replace my clutch. Not insurmountable. The technical manual is pretty good.

What I do know is that you should get to it quickly. A bearing failure could cause more damage and cost more money if allowed to get worse.

Does it do it when you apply the same load (torque) in other gears while accelerating or downshifting?

No it only does it in first when I initially take off. I pulled the sump pan, found some metal filings in there, canít seem to upload the pics.

With no mechanical expertise, based on logic only, if it doesn’t do it in higher gears with the same torque load, it must be in the transmission.

That year until approx 2007 builds had a problem with the trans, and Triumph would fix it at no cost to the owner long after the warranty ran out. My '07 was one. It was a recognised failure but there was not a recall just repairs under warranty if it failed and I would think it still app;ies

I managed to change my torsional damper in my 05 by lowering the engine at the rear.It is still a lot of work, removing rear end, radiator etc. I loosened the front top mounting bolt and used it to pivot the motor down. There is just enough room to remove the cover that holds the damper in place. Good luck!

Thx Jake, so I take it you removed everything as per the manual instructions but didn't have to lift the frame off the motor. My parts should be here soon so Ill be starting on that project. Did you find the front bearing was in backwards, Ive read on some forums that it was installed backwards from the factory?

Hi, yes I followed the factory instructions, however the header can be left in place, just remove the mufflers. Also remove the front fender for clearance if you are lowering the motor at the rear. My bearing was reversed but I caught the problem before it fell apart.You will need access to a press to assemble the torsion assembly. Once again good luck.
