Pretty much as per frayz post above:-
- I filled the sector rod with lead shot (ensure you leave enough of a gap at the end of the rod to allow the the front pivot to be lengthene/shorted when setting up the shifter - I didn’t and had to take the rod back off to empty some of the shot back out 🤦🏻♂️)
- filled the OEM pivot and selector rod boot with red rubber grease when I transferred these over to the PMS shifter.
- replaced the selector pivot bush and circlip with new OEM.
- used some foam draft-excluder-type tape around the flange at the base of the shifter tower, where it mounts to the shell, to give a slight dampening between it and the shell.
I haven’t replaced the bearing in the tower (I bought mines brand new in 2019), but doing the above mines has been absolutely silent in the 18 months it’s been fitted.
that said, another thing to watch out; check the big nut at the bottom of the selector (below the zinc-plated/carbon fibre selector cover) to ensure its tight - mines was slightly loose and resulted in a rattle/vibration. As soon as that was tightened, the rattle went away.
hope this is of some help Russ 👍🏻
