ApplianPar Crankshaft Sleeve Adapter - 7/8 To 1 Inch Pulley Bore Reducer Bushing

Mechanics and DIY enthusiasts, this crankshaft sleeve adapter is one of those simple but incredibly useful tools that can save you from major headaches! This adapter takes a 7/8 inch diameter crankshaft with a 3/16 inch keyway and converts it to fit 1 inch pulleys with a 1/4 inch keyway. The applications are endless - whether you're working on small engines, industrial equipment, or custom projects where pulley sizes don't match up perfectly. I've used this for everything from updating older equipment with modern pulleys to custom engine builds where components needed adapting. The quality is solid - it fits precisely without slop, and the keyway is machined accurately to prevent slipping under load. What's great is how this little adapter can make incompatible parts work together perfectly, saving you from having to replace entire components or do custom machining. The installation is straightforward - just slide it onto your existing crankshaft and you're ready to mount your larger pulley. Whether you're a professional mechanic or a home workshop enthusiast, having a few of these adapters on hand can be a lifesaver when you encounter mismatched components. The value is excellent considering how much time and money it can save compared to alternative solutions. Definitely one of those 'why didn't I think of that' products that every serious tool collection should include!
