Hello all this is my first post so i apologies in advance if I'm in the wrong place or if I'm doing this right. . . But I have Trail fire with (S# J340FH S#098416m D.O.M 09/78) My question is Part Number M66518 Qty Req 2 Part Number M66519 Qty Req 1. When i pulled my secondary off i had 1 of M66518 and only 2 of the M66519. According to John Deere parts book (link below)

I have the opposite of what I'm suppose to have? Any knowledge would be greatly appreciated!! Thanks!

Re: 340 Trailfire secondary shims?
These shims are used to adjust the belt tension as the belt wears. I've never been too concerned about the number of shims. I just add or remove shims to get the correct belt tension. In all honesty when I have measured the thickness of the shims on my sleds, they seem all over the place.
Removing shims will tighten the belt. You can find service and operator manuals on a website called vintage snow.
