Eaton Char-Lynn Hydraulic Steering Control Unit (Orbitrol Valve) - Used

Eaton Char-Lynn cast-iron hydraulic steering control unit (orbitrol-style steering valve) with 4-bolt mounting flange and splined steering-column input bore. Nameplate reads Char-Lynn / Eaton Hydraulics, product number 21?-1177-002 — one digit sits behind the nameplate screw, so the full Eaton number requires verification. Housing also carries the cast markings 12741 WF4 and 129 (casting marks, not orderable part numbers). Application: Char-Lynn steering control units of this style are found on off-highway, industrial, and some marine/commercial hydraulic steering systems. Application not verified — sold by photographs, identifiers, and dimensions. May fit wheel loader / tractor / industrial steering applications; buyer must confirm. Condition: Used take-off, untested. Complete-appearing assembly with shop soil, paint wear, and light surface rust on the studs. No test or pressure-check evidence — sold untested, not rebuilt. Unit will be drained and ports capped before shipping. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
