Question by: Darryl M on Aug 2, 2025, 1:54 PM
got a setup where I might need to swap hydraulic connections around. does this motor give you both side and rear ports, and what happens with the ones I don’t use
Answer by: Customer Support on Aug 3, 2025, 3:43 PM
For installation flexibility it comes with both side and rear ports. The unused ports need to be plugged so you are not leaving an open path for leakage or air entry.
Question by: Bonnie C on May 13, 2025, 9:33 AM
I need to know if this will fit on my machine. It's got a 4-bolt SAE B mount now.
Answer by: Customer Support on May 15, 2025, 6:37 AM
Yes, this motor features a 4-Bolt SAE B mounting flange, so it should be a direct replacement as long as the other specs match your existing unit.
