Not So Pro 3

[Loony661]

Tim, I'm having a fughin fit trying to stop a hydraulic leak on my old JD2640. Looks like it should take a square cut oring, but even that doesn't stop it. I've tried everything and am out of ideas.

Where’s it leaking from?

It is the small size that is giving me fits. Didn't make it to the co-op before they closed. Will try it again tonight. Co-op tomorrow if I am unsuccessful.

Pro Tip.
Secure a spindle of some sort in your vice to drop the rim on and hold it somewhat in place.

The priority valve.

I can't say for sure Randy, unless I could see the counter bore in the valve for the fitting, and the seal area on the fitting behind the hex. But when you say it looks like it should take a square cut or D style o ring leads me to believe it may need what they call a dowty seal washer. It is a super heavy square cut washer with a bonded lip seal on the id of the washer.
Edit: Especially when I see the circular counter bore on the valve. So if it is tapered cut behind that for a round oring than all you need is a back up washer on the fitting behind the hex. Those normally don't fall off as they are almost spun on by hand over the fitting threads.

I think a trip to the John Deere parts department is in order.

Mustang update passenger quarter took a good amount of metal work.

Maybe....but I've seen nothing like this on this tractor anywhere else.

Yes sir Adam, that is a dowty washer. Depending on his bore in the priority valve it may also need an oring behind that and the washer as a back up.

The picture shows the seal being pushed out by pressure behind the hex, or is that Stihl sealant? Do you have any pics of it apart?

That's a little Dirko. I think I'll get a set of dowdy washers and try that with an oring under it.

I got them on. Thank God I didn't need to put in tubes. Put the bottom bead on the rim, used the edge of the fel bucket to hold the rim on the ground about a third of the way across. Used my tire irons to get them the rest of the way. I like the way you think Adam. I guess I achieved what you said in a different way.

I'll get some tomorrow
