B2400HST Hydraulic Problems

[Moose]

Okay, backstory on problem.....

Pressure line going to power steering pump developed a crack, since the previous owner had brazed it (badly) before, I had to have my local hydraulics place make a replacement for me.

Get home, get everything installed and fire the tractor up. Discovered quite quickly that I had not tightened the hydraulic pump fitting (oops). Shut down engine, tightened fitting and cranked back up.

Go through bleeding procedure, seems very stiff. Try front loader, nothing.

Check flow control and it is fully open. Fluid level is good.

Lower 3ph and then try to raise it back up, no go.

Tractor will move forward and backwards without issue (other than dragging front loader bucket on concrete).

Any ideas on what I should try next?

How long did you let it run? Sometimes it take up to 10 or 15 minutes for the air to bleed out of the system and things start working again.

Update....

Completely drained and refilled hydraulic fluid, including cleaning of strainer and installation of new HST filter.

Fired up engine and let it run for 15-20 minutes, still no hydros. I glanced at the hydraulic pump and noticed what appeared to be a little bit of smoke coming off the bottom of it. I do not know if this is oil burning off from where the fitting was loose or something else.

Pump was warm/hot to touch. I pulled the plug on the diverter valve and oil was present.

Any ideas? I do not have the $$$$$ kubota flowmeter/testing kit. ISthere anything else I can use?
