Finally got my sheave back from Coop. I installed it late last night with the .5mm shim thinking it would be alright since that seems to be the most others have ran without issue on a Coop milled sheave. Took it for a spin around the block and I noticed a whooshing noise. So this morning I took it apart and found the belt was rubbing the cover. I pulled the sheave back apart and removed the shim, and in my haste to get it back together I ended up misaligning the cam plate splines and pretty much toasted them while torquing the nut. I was having a hard time getting the belt back up on the sheave lip and I messed up. I was going to take it out today and really see how it does, but now I won’t be able to report on the sheave yet until a new cam plate comes in on Wed. FML lol. Live and learn.
