I replaced the center section on a 460 I bought because the TA and hydraulic pump were bad. A new o-ring between the center section and the rear end was installed along with all other gaskets to do the job. There is a new high capacity filter on one end of the suction tube and all gaskets on that are good to go. The 17GPM pump I installed had what appeared to be a good o-ring in it so I installed it on the suction tube and buttoned it up. I'm running my hy-tran level about an inch above what it should be. Is there any other areas the pump could be sucking air? I put a fully hydraulic loader on it. The large cylinders have been rebuilt and I re-plumbed it and put a few new hoses on so there is a bunch of air to work out of the system. It seems like it's taking way too long to work out. The power steering comes and goes. When it goes I lift the front end up with the loader and cycle it left to right 5-6 times and then it will work for a while. The fast hitch is still full of air even after cycling it up and down dozens of times. There is no weight on it though. The loader is slow and still full of air. Any thoughts? Does it really take hours to work it all out? I was thinking that 6 or so limit to limit cycles of the power steering and both functions of the loader would get almost all the air out making the hydraulics fully functional and the remaining little bit would be gone over time. As soon as I think mine are getting better they get worse and hardly work. There are a couple of areas on the loader that are leaking a bit of hy-tran and it's all milky and full of air.

Today's Featured Article - Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
