Forge ahead is a good word. that would have helped me. But I managed to just pull it towards me so all sorted. Everything else went smooth. so now I have the 64,7 mm installed. looks much brighter and shinier aswell ;D My biggest woories are the "screws" that pop up from the pulley. The look like the are about to go into the belt. But no strange noise nor wobbeling. Will send you a video in a bit.
