I have had the transmission open a couple of times more and still have not been able to get rid of the noise. I ended up by removing two of the original shims from the pinion and either the noise is a little less or I am getting used to it. In first gear the noise is not audible over the engine, and in second and reverse it is just barely. With two shims out the pattern in the prussian blue finally looks like the picture in the book, so I was hopeful that this time it might be quiet. I did get a dial indicator but have not yet obtained a magnetic base so I made a hole in a 1x1x24" piece of wood and used clamps to get it where I needed it. I tried the new pinion position with two backlash settings, one was around .014 which was close to the .015 that D Slater told me was the measurement when he removed them. When that didn't work I swapped a thin shim for a thick one and made the backlash around .030 and it still sounded just the same. I am wondering if I will do any harm to any other part of the tractor by running it for a couple of months with the loud gears. I would like to just put it back together and put the loader back on till spring comes so I can use it to plow snow and move logs around the yard. I am not worried about damaging the ring and pinion since I have a spare set that I got from Marty on ebay a couple of weeks ago for $9.99 plus $26 shipping. They had had no bids and I figured another set might be worth having as a backup. Any advice on whether to run the tractor or not will be much appreciated.
