Farmall 300 hydraulic leak

crsutton81 · Jan 1, 2022

We have a Farmall 300 that is leaking hydraulic fluid from the valve stack behind the dash. I looked at it briefly back in the spring but time didn't permit to follow through to fix it. It appears to be coming from one of the 3 valve stems, but more areas may also be involved on it. I got to the point of getting the hood off in a hurry with no luck so maybe could see the front side. Are there any words of wisdom that might be helpful in removal and repair ? I have to do something as it's terrible enough to throw you off the op platform from slick oil when standing.

You will likely need to take off the entire valve stack. There are orings between them, and in the spools. While there, fix them all, as doing it twice makes no sense. Jim
