OK, Yes I am new to snowmobiles and to make things worse I am from Florida and transplanted up north! I just got my first snowmobile, 90 arctic cat prowler. Here is my problem, I was changing the belt and noticed that there was a crack in between the two halves of the secondary clutch and I couldnt wait for my manual to show up before I took it apart. when I pulled it apart I did not pay attention to which hole the spring was in and there is no marks to show where it had been. Where should it be and what effect does moving the spring to different holes???. the other thing is the crack, it is on the flat surface below the two pulley halves, why did it crack, and what purpose does this part of the clutch have ? it doesnt seem to be used for anything. Will this crack be a problem? Thanks for the help!!!
