Corrected worn pedal cams, now a little tight between high and low, adjust the bolt or adjust the other bit ( can't remember it's correct name ).
David - Speaking of "names", I think what you call "sweet spot", many of us call neutral,.....FWIW,......harold
If everything is in good condition, with the link disconnected, you should have about 1 inch free play in the pedal before it starts to move inward to compress the low band. The neutral should be right at that point, about 1 inch depressed. When the link is installed the clevis pin should go right in with the parking brake all the way forward and the pedal all the way back, then when you press in on the pedal, it will move the clutch lever about 3/8 inch downward. This will correspond with the adjustment of the bolt on the other end of the clutch lever. So when you pull the parking brake lever to the neutral position it will be in the same position as it is when the pedal is in the neutral position.
I said this in many words. See the attached diagram.
One thing I did not make clear above, the 1 inch pedal movement is from all the way up toward the seat to the point where the pedal moves in to begin to clamp the low band. You should be able to continue to move the pedal forward until it clamps the low band tight when the pedal is 1 inch above the floorboard. The low band should be completely loose when the transmission is in neutral.
I believe there was a thread on the new pedal cams causing a problem in setting neutral. http://www.mtfca.com/discus/messages/411944/480261.html?1411867343 The new cams do not allow the pedal to travel back far enough so that there isn't much movement between neutral and low engagement. I believe I'm having this problem which is causing excessive low band wear from slightly dragging. I'll hate pulling the hogs head, but it looks like I'll have to do it.
