I am posting this for my husband, he does not do computers, so here I go. He replaced the hyd pump and now is having trouble with a whining noise and cannot get the power steering to bleed or work. The loader and lift are working fine. He has taken off the regulator block and checked the screen and it is clean. We have replaced the hyd filter and using new 303 hyd oil. If anyone has got any ideas on what to do next we would greatly appreciate it.

This sounds like what my tractor was doing. Had to change the tube and seal that goes between the pump and the cast part of the tractor, when he changed the pump did he check how stiff. A simple check also is to take the filter out and with a hook made from wire pull the tube towards the filter side reaching through the hole of the filter side almost into the pump from the filter side.But that didn't accomplish much on mine I had to chaNGE IT OUT.
We only have one pump. Just the main pump. Can the loader and the rear hitch work well if the intake is not sealing? The tractor does not show any foaming or milky oil so we assume that it is not sucking air. Our tractor is a 1962 year model if this helps any. There is no place to piggyback on this pump. We are stumped.
Your new pump sounds like it is a closed end pump for applications that do not have power steering. You have to have two pumps because the so called piggy back pump is a separate pump just for power steering.
Now, in case he did remove the power steering pump and install it on the main pump, it has to have a gasket and o-ring between the two pumps. The regulator valve assembly has no connection to power steering what so ever.

Quick tech tip, compare the old part and new part CAREFULLY, and if you see major differences such as in the size or number of ports, QUESTION WHY.
It should have been obvious that there was something majorly different about the old part because it was much larger than the new one and had more holes.
