Description & Features

Designed for demanding agricultural and railway maintenance applications, the Danfoss / Eaton Char-Lynn T Series Spool Geroler Motor delivers dependable low-speed performance in a compact ductile iron housing.

Got a T Series Char-Lynn motor that wore out on my harvester, part number on it is 158-3978-001. That the right one to order here?

that supplier part number matches exactly. The 158-3978-001 is the Danfoss Char-Lynn T Series Spool Geroler motor listed here, so you're good to go on the replacement. Just keep in mind the lead time runs about 90 days on this one, so order sooner rather than later if harvest season's coming up on you.

got a hydraulic setup for a grain auger, is this Char-Lynn T series motor the kind folks use on that?

For ag equipment work, it fits the common use case. The listed applications include agricultural augers, along with harvesters and seeders, and it’s a low-speed gerotor/geroler style motor in the Char-Lynn T Series.
