HELP! Doing "routine maintenance" on my lawn tractor (oil/filter change, new blades, etc) and noticed that my drive belt had a cut in it, so I thought I might as well go ahead and replace it before it broke. When I went to loosen the idler pulleys to remove the belt the nuts on the pulleys were seized, and when I hit them with the impact wrench the bolts that I assume are welded to the idler arm broke loose and just spin around now. So I figured I just replace the whole idler arm (GX20787), but when I removed the bolt that holds the idler arm on, I realized that the idler arm also has a rod that attaches to the clutch . . . and now I can't figure out how to get to the pin that I assume is attaching the other end of that rod to the clutch? This "routine maintenance" has turned into a nightmare . . . is there any easy way to get to the other end of that rod so I can replace the idler arm?
