Help with hydraulic pump

I have an older 190xt I believe 1964. The SN is 190 4132 d xt. I have no clue which hydraulic pump is on it. Number on the pump is ac 243727. Is that a double or triple stage pump? I would like to buy a rebuild kit for it but want the right one the first time. Any help on this is greatly appreciated.
 
A quick google tells me it's a Vickers pump. If you got your number from the A-C tag look for another number stamped on the pump itself. Google that number or check with some hydraulic shops or suppliers. I tracked down a kit for my Oliver that way and found one from the other green company.
 
It's not a Vickers pump. Allis Chalmers used mostly Webster pumps.
The pat number looks like an AC pn but does not match what goes on the tractor.
If the tractor has 3 point lift it would have a triple pump. Part number 248735 or 70248735. part number is on the pump flange. There may also be the manufacturers part number also.
 
I would say this helps. I looked all over the pump for the number you described and cant find any other numbers. It does have three point. I bought a pump off ebay and the hydraulics worked great, but no power steering now. The reason I bought the "used" but working pump was because the remotes had no pressure all of a sudden while cutting hay, and stopped moving. put on "used" pump and all was good but no steering now. cleaned the spring and valve in pump and still no steering. Have oil coming out of hydro hoses at steering cylinder when I turn the wheel one way or the other, and lots of it, shoots out about 25ft. My old pump is torn apart now, and the brass plates on the front side of the pump have groves where the gears ride. All the other brass plates look good. Thanks for your help, I will start with that number and see what I come up with.
