Question by: Jerry M on Nov 6, 2025, 6:42 PM

got a corn head auger drive that's been giving me fits, runs about 13.7 cubic inches displacement on the old motor. this the right one to swap in?

Answer by: Customer Support on Nov 8, 2025, 9:39 AM

At 13.7 cu in/rev displacement and a 1-inch straight keyed shaft with a 2-bolt mounting flange, this motor lines up well for auger drive replacements in that displacement range. The 7/8-14 straight thread O-ring ports are a common configuration on agricultural equipment, so hydraulic connections connections tend to be straightforward on most setups. Before you put it under load, fill it with fluid first and run it easy for about an hour at roughly 30% of rated pressure. That break-in step makes a real difference in long-term wear, especially on a working piece of harvest equipment.

Question by: Shawn M on Mar 26, 2025, 8:21 AM

Wondering if this motor'll hold up on my seed drill. We run it pretty hard during planting season.

Answer by: Customer Support on Mar 28, 2025, 6:59 AM

Designed for agricultural applications like seeders and harvesters, this motor is built to withstand demanding use. It's recommended to run it at 30% of rated pressure for the first hour to break it in properly.

Question by: Tony R on Sep 28, 2025, 5:03 PM

got a char-lynn motor with a 1 inch straight keyed shaft and 2 bolt mount, is this 103-1038 the same basic setup?

Answer by: Customer Support on Sep 30, 2025, 6:57 AM

The key identifiers on the 103-1038 are a 2 bolt mounting flange, a 1 in straight keyed shaft, and 7/8-14 straight thread SAE O-ring ports (.875-14 UNF-2B). It is also a 13.70 cu in/rev displacement S Series geroler motor.
