Product Questions & Answers (3)

Question by: Billy B on Jan 27, 2026, 11:12 AM

Will this motor hold up on a grain auger, or is it more for light duty stuff?

Answer by: Customer Support on Jan 29, 2026, 6:08 AM

This S Series Geroler motor is well-suited for agricultural augers, among other applications, so it should handle grain without issue.

Question by: Darryl A on Sep 26, 2025, 7:20 AM

been running an auger on the farm for a couple seasons now and the motor finally gave out, trying to figure out if this one'll hold up better long term, what's the maintenance situation like on it?

Answer by: Customer Support on Sep 27, 2025, 8:31 AM

Breaking it in right makes a big difference with these motors. Run it at around 30% of rated pressure for about an hour before you put it under full load, and make sure the motor is filled with fluid before any load hits it at all. After that, keeping your hydraulic fluid clean is the main thing. The recommended filtration standard is ISO Cleanliness Code level 18/13, and the fluid itself should be a premium anti-wear type hydraulic fluid at 70 SUS viscosity at operating temperature. Stay within the 180 degree F temperature limit and keep case pressure under 1500 PSI and this motor should give you solid service life.

Question by: Lynn E on Jul 3, 2025, 1:44 PM

got a motor with 1/2 npt lines already, are the ports on this one the dryseal kind or just regular npt

Answer by: Customer Support on Jul 5, 2025, 1:43 PM

Port threads are .500-14 NPTF dryseal pipe thread, which matches the common 1/2 NPT port callout and is meant to seal on the threads for a tighter hydraulic connection.
