Helical Drive Gear Assembly with Flanged Keyed Hub - Used, Untested

Used helical drive gear assembly with a flanged, keyed hub — the style used for engine timing, camshaft, fuel-pump, or accessory drive service on medium-duty diesel and marine drivetrains.

Application: Not verified. No brand, OEM part number, or casting number is legible on this unit, so it is offered by photographs, identifiers, and dimensions only. Candidate applications include diesel accessory/blower drive gear assemblies and camshaft or pump drive gears, but no interchange has been confirmed.

Condition: Used take-off, untested. Teeth appear complete with normal running polish; light surface rust and oil residue on the hub, bore, and fasteners. No run, spin, or load testing has been performed and none is implied.

Approximate size: about 8 in gear OD, about 3.5 in overall height, roughly 15 lb shipping weight (estimates — confirm by measurement).

Send us your engine or transmission model and serial number and we will help you compare tooth count, bore, keyway, and dowel locations before you buy.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.

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.
