[QUOTE="bttpe, post: 116992, member: 19457"] Ok I may have this solved although I'm not sure what fixed it. I took the drive motors off again and the Carrier Seals installed by the Bobcat Service Center failed. This doesn't surprise me. They were very nice and helpful and I have nothing but good things to say about them (Bobcat of Columbia, MO). Their installation method surprised me. They had a simple welded tube that fit on the carrier seal and drove it into place with a hammer. They let me watch and ask questions. They did destroy one seal going in and replaced it at their cost. We put the drive motors on and ran it a couple minutes before running all the oil into the chain case again (grrrrrr). When we disassembled another seal was destroyed and the evidence was the spring around the seal off and twisted. We replaced the seal using our method which is a 2" PVC sewer pipe wrapped with tape on the end so that it expands the seal to slide onto the mating shaft. IMO Bobcat should make a tapered tool to do this. Because we had multiple failures we also resealed both drive motors with kits from Loader Parts Source. Together those repairs seem to have fixed the problem. We are limping the Bobcat around the driveway with the chaincase inspection cover off and pushing/pulling the drive levers with a log chain and our feet (I don't recommend this it is not a safe practice) However, we didn't see anything up on jackstands and wanted to move around under load. Fingers crossed we are putting it back together and will give it another try. [/QUOTE]
