i am new to this forum and its helped me out quite a bit, i am currently putting back together a 2004 Kodiak 450 for a friend, he had teared it down completely and lost a bunch of parts, as i was putting the middle driven gear back in i noticed there were no shims, i have looked through the manual trying to find the markings and numbers for the formula to find starting shim thickness but i cant find 2 of the numbers so i have no idea where to start. any help will be appreciated, thanks.
