Got the wife’s XC 500 back from a shop for some unrelated repairs. As I’m looking over the sled I notice the secondary is able to slide in and out on the jackshaft with the bolt torke down. I understand the secondary needs to be shimmed and so it is. However there is about a 3/8 inch of slop between the clutch and shims. How much slop should there be? Or should the clutch be snug with the shims? And how snug?
