Description & Features

Rated at 17.90 cu in/rev displacement and 351 Nm of torque, the Eaton Char-Lynn H Series Geroter Motor is well-suited for demanding agricultural and industrial applications including harvesters, seeders, agricultural augers, and industrial sweepers and floor polishers. The 4-bolt mounting flange provides a stable, secure installation, while the 1 in. straight keyed shaft and 7/8-14 straight thread O-ring ports support reliable connection in working hydraulic circuits.

Built around a spool geroler design, this motor features extended bearing life and an increased shaft seal for durability under sustained load. The compact form factor allows integration where space is limited without sacrificing output. Maximum case pressure is rated at 1,500 PSI, with a maximum operating temperature of 180°F. Premium anti-wear hydraulic fluid is recommended, with filtration maintained to ISO Cleanliness Code level 18/13.

Product Questions & Answers (1)

Question by: Cindy A on Feb 15, 2026, 2:50 PM
motor's been sitting a while and we're fixin to put it on a harvester auger setup, what's the break-in procedure look like before we throw it under full load?
Answer by: Customer Support on Feb 17, 2026, 7:33 AM
Run it for about an hour at roughly 30% of rated pressure before you put any real load on it. Make sure the motor is completely filled with fluid before you ever apply load at all. Skipping that step is one of the faster ways to shorten the life of a motor like this, so it's worth taking the time even when you're in a hurry to get back in the field.
