I appreciate your reply also. It bears the same value as 1370rod's reply.
The reason his made sense to me was my experience replacing a broken pedal spring on a 970 many years ago. I fought that spring for an hour with various pairs of vise grips to no avail. I could get it so close, but never quite stretched enough. I finally called a neighbor that was an IH mechanic. He told me of the trick to put coins between the coils on each side of the spring. They were not easy to insert, but after you did that the spring was long enough you did not need to stretch it at all. Just install it, then step on the pedal and all the coins fall to the floor.
So thinking of that experience, I thought someone not knowing the trick might have given up and found a lighter spring than was stock. Just a guess.
I think I will try using some cable lube on the pivot point to start with. I think the graphite in the lube might last longer than a light oil.
Again, as I said in my original post......Thanks for the help to all that reply.
