Aright...so I took the chain case cover off in a track swap.....everything was going good until I went to put the chain back on. The upper gear has 2 spacers....one a bit wider than the other. I'm pretty sure that the order of install was smaller spacer, gear, larger spacer, case etc....because that's the order I thought they came off in. When I look at the parts explode view, it looks like wide spacer, gear, smaller spacer case etc.... Can anyone help me confirm the proper order? I feel so dumb for not remembering....
