Designed for diverse configurations and sizes, this 10000 Series 57.3 cu in Geroler should work as a replacement, as long as the part number 8573-004 matches your old one.

been trying to track down a geroler for my 10000 series unit and keep running into the wrong part numbers, is 8573-004 the right one for the -004 configuration?
Question by: Jean M on Jul 19, 2025, 7:53 PM
That part number is correct for the -004 variant in the 10000 Series. The full product covers the -002, -003, and -004 configurations, so just make sure you're matching your specific suffix. The 8573-004 is the Danfoss Char-Lynn supplied part, and it carries the catalog number C1EZ84 if you need that for your purchasing records.

i keep hearin “geroler” on these Char-Lynn motors. what exactly is this part supposed to do
Question by: Carl S on Dec 16, 2025, 5:59 PM
Inside a hydraulic motor, a geroler is the internal gear set that creates the displacement as oil flows through it. In this case it is a 57.3 cu in per revolution geroler meant for Eaton Char-Lynn 10,000 Series applications where consistent, precise performance matters.
