Harley owners and mechanics, this mainshaft sprocket wrench is about to make your transmission work so much easier! Specifically designed for that stubborn 1 7/8 inch nut on Harley front transmission pulleys, this tool fits 1936-2006 Big Twins and 1999-2006 Twin Cam models (except 06 Dyna). The 5.5 inch depth gives you plenty of reach, and the 1/2 inch drive works perfectly with your ratchet or breaker bar. Made from high-quality steel with a black oxide finish that resists rust and corrosion, this wrench is built to last through years of use. It's specifically designed for removing and installing the nut that locks the transmission pulley in position, making belt, pulley, or sprocket changes way faster and simpler. Just remember - this isn't for impact gun use, and you'll want to confirm your specific model compatibility before ordering. If you're doing transmission work on your Harley, having the right specialized tool makes all the difference between a frustrating job and a smooth repair. This wrench pays for itself the first time you use it, saving you time and preventing damage to expensive components. Serious tool for serious Harley work!
