William, if your rear PTO seal is anything like mine was your in for a real struggle. I ended up taking the whole thing apart, removing the big drive gear on the inside and driving the shaft out rearwords. I then tried a variety of pullers both homemade and store bought. I could tear the seal apart but not remove it. I ended up CAREFULLY chiselling it out. This was the origional seal from the factory (steel and felt). It was unbelievably strong and was really stuck in there. Getting the gear off the shaft was diffacult also. There is no set screw, just the bolt on the end, but this is not a tappered shaft so it comes off hard the whole way. The belt pully seal is only half of your problem there. You'll most likely need to replace the spacer tube also as it will have a grove warn in it. These are available from the dealer. $20 or so last time I checked. That seal is easy to replace as the housing comes off with 3 bolts if I remember right. You'll need a new gasket for this and a new gasket to put the PTO housing back on the tractor if you do end up removing it. Also there is a big, 4" or so, rubber O ring between the PTO and belt pully housings. This is real easy to pinch during reassembly so be careful. Might as well change the transmission lube while your at it as you'll need to drain it if you remove the PTO housing(the belt pully housing has a small pipe plug at the bottom to drain it also). Good luck. Dave...
