The Fordson Tractor Pages Forum

My Super Dexta is a 1964 model with the hydraulic auxiliary chest shown in the picture below. I have a substantial oil leak from the areas circled in red in the picture below.



There appears in the picture to be an oring behind the retainer. I have removed the roll pin, but I don't see a way to get the retainer out.
Does anyone here have any suggestions on how to proceed?

I had trouble with the image, hopefully it shows now.

Hi,

I only one replaced 1 o-ring because it was blown out. maybe you can put some air pressure on it from the inside to get it out?
there are aftermarket kits available with the o-rings and new retainers.

The one of the flow control should come out easily, since there's a spring behind it. Just drive out the pin.
Do you have the unit on the bench? Can you fiddle the remaining plugs out with a small screw driver?

Thanks for the replies Mathias. Yes, the unit is on a work bench and the roll pin has been removed. I tried blowing the retainer out with air pressure, that didn't work. Do you know what ports are necessary for the lift to work? In other words what holes can I block and still have a working lift. I don't need auxiliary ports.
I will probably just buy a new gasket and put it back together, I have weeds that need to be cut!

can you remove the retainer without taking the unit off the tractor?

I still have not gotten the retainer out with it on the workbench. But, yes you can get to some of them with the valve chest still on the tractor.

sent for the cavalry! mate who is a fitter, thinks after getting the unit off, could be the gasket so ordered one along with a new seal kit,we will try this first

Success! Maybe. I got the retainer out, the key I believe is to allow penetrating oil to soak in for a week or more. Then, there is a small hole, approximately 1/8 inch in diameter in the center of the retainer. I used a wood screw forced into the hole. This pushed the retainer further into the bore. But I was able to work the retainer back and forth until I got it out.
The old O-ring was brittle and flat, it broke apart when I removed it. I put a new O-ring on and made a new gasket. Installed the chest on the tractor and lifted a bush hog a few times. Didn't see any leaks. Once I have used the tractor I will know for sure but at this point things look good.

how come the oil doesn't come out of the hole

The hole does not go all the way through the plug.

Hi,

Isn’t it a threaded hole from factory so you can connect a puller to it?

That would have been an excellent idea, but I couldn't detect any threads in my plug. The screw did bite in enough to work.

mine is not wanting to move, would heat help?

There are rubber O-rings in the auxiliary valve chest. Heat would no doubt destroy them. What are you trying to move exactly?

trying to remove the retainer, now its out and back in with a new seal. Had to get a mate with a press to put it back in held in by a roll pin
