Hey guys just wanted to share a tad bit of info that maybe helpful top you or a friend down the road. Oil Seals is the topic here and all tractors have them. This little trick I am going to share is not a 100% guarantee for a fix but has worked for me several times many years back when I would race off road motorcycles and we would have fork seals leak. I just did this with success yesterday to my simplicity transmission.
Ok as we know all an oil seal does is create tight seal around a shaft to hold in the fluid. Many times when a seal leaks its not really ripped or torn it may just have some debris in it. If you take a business card and wrap it around the shaft and insert it into the oil seals and turn it back and forth a few times it will release the debris and allow your seal to seal yet again.
When I did mine yesterday I was able to retrieve some string puled it out ran the card again, used some brake cleaner to clean up the area took a look this morning dry as a bone...checked hydro (trans fluid) and its full. so no more leaks.
