Help finding this relief valve

[John V]

Howdy, I'm looking to find a matching relief valve to this:

Tried scratching the paint off the valve to find a part number, to no avail.

The valve block has 613 written on the side of it.


Thread diameter measures .65in on the dot


It's on a Yanmar mini x. Yes I could order from the dealer, but they want an arm and a d*** for it. So I'm having fun playing detective.

Thanks,
John

Pull it apart and start changing o-rings?

There's nothing wrong with the relief valve. I need to add two relief valves to the PTO circuit.
