Product Questions & Answers (3)

Question by: Lyle M on Aug 18, 2025, 4:42 PM
Been running a grain auger setup and the old motor finally gave out. This a direct swap if the shaft and mount specs line up?
Answer by: Customer Support on Aug 20, 2025, 6:37 AM
For a 2-bolt flange and a 1-inch straight keyed shaft, this motor fits right into a lot of standard auger configurations. The port size is 7/8-14 straight thread O-ring, so as long as your existing fittings match up on all three points, you're looking at a clean replacement. The 2.80 cu in/rev displacement is worth confirming against your original motor spec too, since that affects your speed and torque output at a given flow rate.
Question by: Phil C on Dec 27, 2025, 6:52 PM
got a hydraulic auger motor to swap out. is this one the 2 bolt mount with the 1 inch straight keyed shaft?
Answer by: Customer Support on Dec 29, 2025, 5:03 PM
It matches a 2 bolt mounting flange and a 1 in. straight keyed shaft, so it lines up with setups that call for that mount and shaft style.
Question by: Brent A on Sep 24, 2025, 11:20 AM
Will this motor hold up okay if I'm running it pretty steady on a harvester?
Answer by: Customer Support on Sep 26, 2025, 6:20 AM
Designed for agricultural equipment like harvesters, this geroter motor should perform well under continuous use, assuming you stay within the recommended operating temperature of 180°F and case pressure of 1500 PSI.
