For sale is a Huge Hydraulic Motor. Char-Lynn, 36-02, Product Number 9-1-31-003 775 15 made by Eaton Corporation. This motor weighs about 100 lbs, and has a 2 1/8" shaft (all dimensions approximate). Despite the visible rust from storage, I could not find any evidence that this motor has ever been mounted, there are no scratches on the shaft or the drive key, and the openings are all sealed with what looks like factory plugs. I bought this motor from a stockroom of a liquidating factory.
See the PDF below for more info. This motor looks like Char-Lynn 10000 series.
