I just got my TT2 today, I've noticed there's a small black "rubber band" wrapped around the 33 1/3 pulley, but not the 45 pulley.
First I thought it was the residue from the old belt, uppon close inspection, It looks to be put on by someone at one time, not sure if it was put on in the factory.
So for the TT2 owner, would you look at your pulley see if yours have that rubber thing around the 33 1/3 pulley?
