So I have the 2005 engine that is all taken apart and needs reassembly. Claviger and 1olbul stayed over on their way home from RAA West. We went through the engine and trans and found it to be in great shape. The torsional damper bearing is in excellent condition but we were trying to determine if it was installed with the seal face the right way. Currently it is installed with the sealed face away from the gear and the open face towards the gear.

I have been searching adds for the torsional damper to see which way it should be installed. I have seen them installed both ways. The 6 adds I have seen showed 3 one way and 3 the other way.

Even my Triumph Shop Manual has drawings showing it both ways.

Which way is right ? Who has the definite answer ?
 
Option 1:

Option 2:


@warp9.9 As I understand it, Option 2 is the correct orientation, is that correct?

Of the ones I see listed for sale, all the post 2009 are installed as Option 2, for the early year listings I find a mix of 1 and 2.

I tried digging through my pictures from my tear down, but did not capture this in any picture.
 

Did find this.
 
And warps response confirming that Option 1 is incorrect:
 
Yes sir you are correct. The side of the bearing with no shield goes forward so it can be de oil from the gear box. Like in option #2 !!!
