Steering valve

[Dan Mo]

I’ve got a 464 international. Been sitting several years. Got it running and the priority valve was stuck. Have hydraulics now but the steering valve is spraying oil bad. Will a seal kit fix it or time for a new steering valve?

I would start with getting the priority vavlve working correctly whether by getting a different one or freeing up yours. Once that is done then the leaks might quit by having the correct volume to it with the correct pressure. Then if leaks persist solve them then. The priority valve should be in the MCV i think. So you may need to either pull it off to get to it easiest or just remove the valve from the MCV on the tractor. Once it is freed up things may return to normal. IF not then let us know.

Ok thanks

OK, I am letting you know I for sure got the priority valve freed up. I had it out of the valve body and it slides up and down in the bore easily. The steering valve is still spraying oil a lot looks like maybe it was leaking a little bit before it was parked, but I think there is a piece of gasket. It doesn’t really feel like an O-ring hanging out the back of the steering valve. I’m going to pull it off. Can I pull the bottom off of the steering valve and replace the gasket or is that a big ordeal?

Also, the steering, lift and remotes and PTO are all working, when you steer it sprays hydraulic oil pretty heavily

Are we talking about the hand pump or a different part? The hand pump will leak out the top around the shaft or at the bottom from the band under the cap. If it is leaking from under the valve body in the MCV then it is probably an o-ring that has been nicked or a flattened out portion from time and being squeezed in there. Other wise I guess you would need to explain the leak in more deatail or a picture of it.
