Got an engine project where the parts don't quite match up? This crankshaft sleeve adapter is here to save the day! It converts a 7/8 inch shaft up to 1 inch, letting you use your existing pulleys or clutches on different engines. Made from industrial-grade cold-rolled steel, this thing is built tough - CNC precision machining means perfect fit and durability that won't let you down. The 3-inch long adapter comes with a step key that handles both 1/4 and 3/16 keyways, so you're covered for most applications. Installation is straightforward - just slide it onto your shaft, align the keyway, and you're pretty much good to go. Sometimes you might need to gently tap it into place with a small hammer for that perfect snug fit. Perfect for small engine projects, go-karts, lawn equipment, or any situation where you need to adapt between these common shaft sizes. The silver finish looks professional, and the quality construction means it won't wear out or fail when you need it most. Whether you're a professional mechanic or a DIY enthusiast working in your garage, having the right adapters on hand can make the difference between a project that stalls and one that runs smoothly. This little adapter delivers big performance where it counts!
