Designed for serious Harley-Davidson maintenance, the Harley-Davidson Big Twin Mainshaft Sprocket Lock Nut Wrench is a rugged steel tool built to handle the 1-7/8" mainshaft lock nut on older Big Twin models and Twin Cam engines. Its precise fit locks the transmission pulley in place, making belt, pulley, or sprocket changes quick, clean, and safer by preventing movement during removal or installation. With a durable black oxide finish, this wrench resists rust and stands up to the grime of frequent workshop use, giving you reliable service ride after ride.
