Long 445 hydraulics

I think that pump is a simple gear pump. If it is there is no simple rebuilding it. The gears and housing both wear. So you would have to machine the housing and replace the gears with bigger ones. A new pump would be cheaper.
 
Question. My manual call for 17 qts. of fluid for the transmission which feeds the hydraulics. There is a large threaded plug under the seat. Does any fluid go in there? Put fluid in fill hole in front of shifter and checked dipstick behind shifter (right side) until full. Looked in the large fill hole under the seat and see no oil. Don't see another dipstick in the rear. It looks oily in there. Thanks for any help. Hope I posted this right by asking another question. John
