I am looking for a little info here. All of the sudden with a Brand new belt I have to adjust my deflection out so far that sled would be in 4th gear. With a used belt, I can adjust the deflection so the belt is sitting in the right place, but when the sled is cold it really doesn't want to grab the belt from a dead stop. I was trying to picture it in my head, do i place shims between the sheave and the spider or is there shims under the sheave? Ever since I bought this new primary it hasn't performed like it should from a dead stop. I figured since it was the proper part number clutch from cat for the sled that I wouldn't have this issue.
