After replacing the solenoid that Terry had sent up, Terry finally sent up a new PTO pump that I received last Friday. Before I changed the pump Terry had sent a new PTO relief valve and asked me to swap this hoping it would be that simple, no luck. So, after an agonizing several hours I replaced pump (pretty darn tight in there) and guess what still no pressure from the PTO pump. I threw my hands up and called Terry on Monday and asked him if it would be OK to bring it down on Tuesday. Terry of course said they would be ready for me when I got there. For most of 5 hour trip to Tazewell I kept on thinking what did I do to the machine to cause the PTO to stop working? Remember the PTO worked fine until I changed the filter. My pea size brain unfortunately came up with zip. After a short wait at Power Trac, Eddie whisked my 425 away to the mechanics shop. I asked to go along hoping to learn more but unfortunately due to liability concerns no customers allowed in the shop. I sat and talked with Carol (very nice) and then went up to talk with Scott in the showroom. Just before lunch time Terry came walking in with answer to the mystery. It turns out it was the relief valve all along. The adjustment that regulates the pressure was incorrect which was why the blades were turning slow. Now as soon as Terry told this to me my pea size brain kicks in as I stupidly hear myself say now I wonder how that got messed up? I have a flash back to when changing the filter for the first time I was having a hard time remembering where Terry told me to thread the hose in for bleeding the system (9 months ago). I had thought it was pretty easy to get to so I remembered unscrewing one of the relief valves and realized no this couldn’t be it so I tighten it back down and proceeded to the cap on the side of the tram pump. I had totally forgotten this until standing there at Power Trac feeling like a total you know what. Terry, Eddie and Scott were very gracious and didn’t make me feel any dumber than I did. The trip was not a waste though; they replaced a leaky rear hydraulic wheel motor, replaced the seal around the gas tank which had been leaking since day one when more than half filled, tightened the large articulating nut which I don’t own a big enough wrench for (1 and 15/16ths); it was pretty loose and cleaned up the entire machine, all under warranty. I sure have learned a lot more about hydraulics and the PT 425 which is a good thing. In addition I was impressed with the service from Power Trac. I apologize for the long post and thanks for all the feedback and everyone’s input on this forum and these pretty darn incredible machines.
but I cleaned most of it up. By the looks of it the wheel motor leak has been leaking longer than since I changed the filter. This wheel motor is on the opposite side of the filter in my machine. It looks like it has been leaking at the axle, Do you know if there is some kind of seal at that point that could be bad?
