Posted 7/5/2010 16:28 (#1261476) Subject: Mac Don 972 Draper Head tracking problems
One side is tracking to the rear of the header, the draper guide comes out of the groove on the idler pully and it rides toward the back. My fixed pully is set like it says to be, where the rear is an 1/8" tigher than the front of the idler. I am starting to think that the belt is stretched too much, or perhaps replacing the belt. It looks better than the other side, and I was wondering if I were to shorten the belt an inch or so, would that fix the problem. One thing I noticed is that the driving pully has the rubber coating that is partially gone on the end of the pully. Perhaps I should replace that....Will that cause the problem?
