I am looking for a hydraulic pump for my HD7 (1944) My housing froze and cracked beyond repair last winter! It is a Baker BMA-330 pump made by Hydreco, it has a 1 1/8" x 2" input shaft with single keyway and a 6 bolt rcircular mounting flange with 1 1/2" NPT in and out lines. Please email me!! Thanks!

Unsure of this unit but on trying to find a good used pump for HD5G found they are few and far between in servicable condition. Might look at more modern pump. Then if you just need a case it might be possible to find one. With straight shaft shoul;d be easier than the HD5 as they used a splined shaft.

I found a brand new Vickers pump for a HD5 but could not come up with connector to engine as it was first style AC used on the 5

Where you at in Idaho? There should be a hydraulic service company in Boise or Spokane, Wa; the best bet with Hydreco long gone, check if the pump can be interchanged then use the replacement names/numbers to try to locate a used or rebuilt unit.

I have had similar experience with old semi-trucks trying to locate P/S pumps or ancient wet kits functional and had to cross the manufacturer through a hydraulics service to get an appropriate unit for them.
