Re: YT6700 transmission rebuild

Finished cleaning up the hydro and installing new thrust plates and bearings for the pump side of the hydro. The swash plate race was pitted beyond repair so I installed a new thrust washer over the old groved race, added a new thrust bearing and polished down the original pump face plate. The faces of the pump cylinders were scored and pitted also so they also had to be polished to a mirror finish. Here are some pictures of the procedure. Lots more pictures if anyone is interested. These pics have been downsized for the net but I have 26 pictures of the entire build in very fine detail and closeups. The one picture is of a small fraction of the metal filings that were removed from the oil passages. The entire unit was flushed with lamp oil, cleaned with carb cleaner and blown out after soaking. The problem was caused by lack of maintenance of the hydrostatic unit and I would strongly suggest annual oil changes. Not an easy job but sure beats a rebuild.
