    fit perfect

    Put this motor on a hydraulic auger drive and ran it through some tough ground — clay, rocks, the works. Held pressure well and didn't get hot even after extended use. Build quality feels solid, splined shaft seated clean. Really happy with it.

    Bolted right up to the SAE A flange without any fuss, shaft fit the spline coupling perfectly. Only reason I'm not leaving full marks is it took about a week longer to ship than I expected, but once it arrived everything checked out fine and it's been running strong since.

    Replaced a worn-out orbital on our skid steer attachment and this one dropped right in. We've put a good amount of hours on it already and it's holding up great. Definitly buying from Northern Hydraulics again.
