Bob, Not sure what model 350 you have but the following info comes from 25 years as an owner of 350C's and a 450C. Scientific info...no but perhaps just my imangination, seems to help though. I found that keeping WD-40 on the cylinder rams for the track tensioners seem to help. I have also parked the dozer down hill so that the WD-40 will soak in and help loosen the ram. Sometimes I have had to used a small sledge hammer and "TAP" around the ram housing. Don't hit the chromed areas of any cylinders. While tapping have someone try to pump grease in. Since I have been keeping WD on the cylinders I have not had a stuck tensioner. Also try to keep that area free of dirt build up, yes I know it's hard but I always spend a few minutes to keep it clean. As far as grease peeing out; This happen to me one time after a 350 was sitting for a long time and the track was to tight. I wanted to loosen it so I removed the bolt next to the grease fitting thinking that it would let some of the grease out and give a little slack in the track. After I removed the bolt I moved the tractor back and forth a little and it brok free and I got my slack I was looking for. So I put the bolt back in and proceded to pump the track back to the tension I like and discovered the grease I was pumping in was coming out a little hole. What I didn't know was when I moved the tractor there was a little tinny ball (about 2 or 3 times the size of a BB) that came out with the gob of grease. That little ball is needed to seal that pee hole. What I did was order 4 little balls (so I have spares) and put one in the bolt hole and started pumping grease in and that little ball found the right place where it was suppose to seat and it all worked out. I have also found myself chasing the proper track tension. Tightening it, loosing it...now if it's loose then I only go a half to one pump of grease. They seem to tighten up a bit after use. Good luck..
