H Series Geroter Motor, 8.90 cu in/rev, 2 Bolt Mounting Flange, 1 in. Straight Keyed Shaft, 1/2 NPT Ports, Compact yet powerful|Extended bearing life|Increased shaft seal

For a 2-bolt flange configuration with a 1-inch straight keyed shaft, this motor lines up with that kind of auger application directly. The port size is 1/2 NPT, so as long as your existing hydraulic connections matches that, you're in good shape on the connection side too. Before you put it under full load, plan on running it easy for about an hour at roughly 30% of rated pressure. That break-in period makes a real difference in how long the motor holds up over time.
