Cross-Referencing Heavy Motions Inc. Parts

Heavy Motions markets much of its line as direct interchange for major hydraulic brands, which makes it a practical source when an OEM part is discontinued. HM589-series PTOs are 100% interchangeable part-for-part with Chelsea 489-series units, and H51-series gear pumps replace Parker/Commercial P51-series pumps. Gear housings, relief valves, and other component parts are engineered as aftermarket replacements for Parker, Eaton, and other discontinued OEM products. If you have an obsolete Parker, Eaton, Commercial, or Chelsea part number, we can cross-reference a Heavy Motions equivalent by flow, mounting, rotation, and port configuration. Send the OEM number or nameplate data and request a cross-reference quote.
