John Deere / BorgWarner S300-series turbocharger, OEM data plate model code S300W069, serial C0306 2044 R. The John Deere leaping-deer logo is cast into the compressor housing. The John Deere P/N line on the plate reads RE5?9644 with one digit obscured, so the full part number requires verification and is not published as confirmed. Application: John Deere diesel engine — specific engine family and rating are not verified. May fit John Deere PowerTech applications; buyer must confirm. Condition: Used, untested rebuildable core. Heavy surface rust on the turbine and center housings, dirt and oxidation on the compressor housing, corroded oil fittings, casting-edge damage near one turbine-housing boss, and no wastegate actuator visible. Compressor wheel appears complete in photos, but shaft play, wheel condition, and housing integrity have not been inspected or tested. Sold as a core for rebuild or parts. All ports will be drained and capped for 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.
