The hdy pump is powered by the engine. I think it is a gear connection. The pump leaks into the engine at the spot it is mounted onto.

On my tractor TN95A
The high-pressure system pump mounts on the right-hand side of the engine. It is a fixed displacement, open-center, gear type pump driven by the engine timing gear.
When operating orbital motors or front-end loaders, it is desirable to use a factory installed optional 64 1/m (16.9 g/m) 16.9 g/m pump on tractors with a mechanical shuttle transmission, which will include the installation of an oil cooler.
The type of hydraulic pump installed in each system depends on the configuration of the tractor, and the transmission.

In other words.. follow the hydro lines & find the pump.. IF its mounted outside the engine & is gear driven..
The seal that holds the fluid inside the little box might have ruptured..?? & filling your engine oil w/ hydro. fluid.
Its easy to check but requires the pump to be pulled away from the engine..or removed..
Just blow air into 1 side while blocking off the other..
OR pull it back far enough to see the gear/seal & run the machine..
I'm not familiar w/ that machine so I don't know if that's possible.??
Check your workshop manual.. & if u say, I don't have 1.. GET ONE..they're worth their weight in gold..{hydro. fluid} lol

Hi thclimer,
Thank you, thank you, thank you! That is exactly what I needed, and from Jinman too. I sure miss him. He probably would have been all over my post if he was still around. Many thanks to all who responded to this matter. I will keep you posted on the outcome of all of this.
Thank you kindly! All of you!
Kind Regards,
Steve

Yes Jinman is clearly missed, he had great insight at troubleshooting.
Hope its not too difficult for you to have your hydraulic pump rebuilt.

Hi TheClimer,
Thanks again for the specific information you sent. It got me over a tough row to hoe with all the other stuff going on here. I will be getting to it soon.
Sincerely appreciative!

Those gear pumps are super simple to rebuild as long as the metal parts are in good shape.
Usually an overpressure at some point blows the o-rings. After you get it rebuilt check the relief pressure on your system.

Hi Dwayne,
I got the pump out. There is only one seal? Jinman mentions 2 seals? Where can I find the squared off o-rings? Does anyone have an exploded view/ schematic of the pump? Much appreciation in advance!
