MM 445 hydraulic pump

I’m looking for a hydraulic pump for a Minneapolis Moline 445. I’ve called AGCO and they were unable to help me. Can someone help me out?
 
Thinking there is two different pumps. 3pt and some with power steering. Would have to be used one or rebuilt. Part # on pump body.
 
Can not find any numbers on the pump. I found the part number on AGCO. Part # 10A11289 hydraulic pump with flow control valve. There’s a line that runs from the pump to the front of the tractor to the power steering then back to the filter housing.
 
Be careful when removing so you don't drop the coupler inside, and they had different spline counts.
 
Original pump 10A8012. Crosses to 10A17560. Used on 5 Star 335 445 and early M5. They are rebuildable. I redid one for my M5.
 
I believe someone has had the pump off and apart before. When I took the pump off there was not a coupler and the pump wouldn’t turn. Curiosity got to me so I took the pump apart, and saw that there was some damage to the bearing plus all the needles weren’t there. Missing about a quarter of them.
 
May I ask were I would be able to find this pump? I’ve tried a couple different places and they were not able to find a pump for me. What company carries it? I would be very appreciative of the information, so I can get this tractor back together.
 
If core isn't to bad get it rebuilt or do your own. The Torrington bearings (needle) have to be changed anyway. Have to be cut out. Not really a MM pump. On casting is Webster part #.
 
I believe that is the original number for the standard pump. Replacement number was the 10A17560. I just got done resealing the one on mine. If the center section on your pump is flush with the other two sections of the pump it is the standard pump. The replacement pumps, the center section is larger and sticks out farther than the other sections of the pump. Also, the replacement pumps were grey in color.
