Product Questions & Answers (2)

Question by: Ronnie B on Jun 21, 2025, 1:13 PM

what's the torque output on this motor and is it enough for running a grain auger under heavy load?

Answer by: Customer Support on Jun 23, 2025, 6:33 AM

At 491 newton metres of rated torque, this motor handles the kind of sustained demand that grain augers put on a drivetrain without much fuss. That torque figure puts it well within the range used for agricultural auger applications, which is one of the listed uses for this exact unit. Just make sure you run it through the recommended break-in first, about an hour at 30% of rated pressure before going to full load, and that the motor is fully primed with fluid before any load hits it. Skipping that step tends to shorten bearing life faster than anything else.

Question by: Dwight K on Jan 14, 2026, 9:37 PM

got an auger that needs a new motor. is this one the 2-bolt mount with the 1 inch straight keyed shaft and them 7/8-14 o-ring ports?

Answer by: Customer Support on Jan 16, 2026, 6:47 AM

The key details on this motor are a 2 bolt mounting flange, a 1 in straight keyed shaft, and .875-14 UNF-2B SAE O-ring ports (7/8-14 straight thread O-ring). Displacement is 17.9 cu in per rev, so it matches applications like agricultural augers, harvesters, and seeders where that size motor is used.
