Char-Lynn Hydraulic Motors

Char-Lynn is a hydraulic motor brand built around gerotor and geroler torque designs for industrial, agricultural, construction, and mobile equipment. The line was developed under Eaton’s hydraulics business and moved to Danfoss Power Solutions in the August 2021 sale of Eaton Hydraulics to Danfoss. Danfoss continues product support and replacement-parts availability through its Power Solutions division, so legacy Char-Lynn motors stay serviceable under current ownership. Northern Hydraulics supplies Char-Lynn hydraulic motors and cross-references them for customer applications, with roughly 68 Char-Lynn units cataloged.

Char-Lynn Product Lines & Series

Char-Lynn motors are low-speed high-torque (LSHT) units built on gerotor and geroler torque elements. The full range is cataloged as Char-Lynn hydraulic motors, with the disc-valve LSHT designs grouped under gerotor and geroler torque motors. The established series families include:

• 101 H-Series gerotor motors
• 103 Series motors
• 104 6000-Series geroler torque motors

Each family pairs a specific displacement, shaft, and port configuration with the application, so confirm the model number and series when matching a replacement against the Char-Lynn geroler torque motor range.

Cross-Referencing Char-Lynn Parts

Many original Char-Lynn part numbers now map to Danfoss Power Solutions equivalents following the 2021 acquisition, and that interchange is where most service questions land. If you are holding a legacy Char-Lynn model number from a 101 H-Series, 103, or 104 6000-Series motor, we match it to a current equivalent motor or replacement part by displacement, shaft type, port pattern, and mounting flange. We cross-reference Char-Lynn motors against equivalent units so you do not have to retire serviceable equipment over a discontinued catalog number. Send us the Char-Lynn part number or nameplate data and we will return an equivalent. Request a Char-Lynn cross-reference quote.
