Sorry for the delay. Have to many projects going. I attached two pictures. It looks to be cracked where you can see the shiny ring around where the bolt. I probably done it when I tightened it too much.
any ideas where I can find one? Been looking online but nothing so far. Everything says it’s discontinued.
If it were me I would make a new flange and replace the pipe with hose.

It takes very little of both. Any decent hydraulic shop should be able to do that. Post a full kength picture of the pipe.

Well, of course I did not think about a local hydraulic shop!! Thank you for that advice! I’ll post a full length picture tomorrow sometime. Thank
You again!!! I really appreciate your insight!

I'm really not seeing a crack, and I have a 30" computer monitor.
Please point at where you think the crack is?

I am agreeing with @North Idaho Wolfman on the “I don’t see a crack”! I also thought what @TheOldHokie thinks is suspected crack but that just looks like pooled oil with light reflecting off it now.

I don’t think the size of the bolts and the (probably aluminum) material they thread into have the strength to do damage to that hunk of steel, but I concede that anything is possible.

I personally don’t see any reason why there would be a leak on the face of that joint, so I have no idea what is going on.

@Smokey160 - please clean that part up a bit to remove the oil since it reflects the light oddly in pictures. I would use Berryman B12 or a non-chlorinated brake parts cleaner in a spray can to blast it clean. You should remove the o-ring first or it will probably get lost. Then take another picture of the part after it dries without the o-ring and another with the o-ring. I guess if you have some third hand available use a sharp pencil point or something similar to point to the suspected crack to help us see what you are looking at.

I attached a few more pictures at different angles, and pointing to where it kind looked cracked to me.
Also, I know this may not matter, but I remember when I gave the Kubota dealer the part number for the O ring he said they had changed the number and gave me this one. It does seem to fit right but as you can see where I laid it on top that you had to manipulate it in

I have attached some more pictures and tried to show where I think it is cracked using a pencil. I also attached a picture of the o ring because I want to make sure I have the right one. The Kubota dealer told me when I gave him the part # that it had changed and gave me this one which also goes on the other end too. They work fine but is it right that you have to manipulate them into place - you see how it sits on top without any manipulation?
