The Drive Mandrel Stepped Steel Washer from MOROSO (MPN 97100) is a precision fastener component designed for engine builders and performance mechanics. It is particularly useful for applications involving harmonic balancers and crankshaft assemblies, ensuring reliable clamping load distribution under extreme centrifugal forces.
This stepped steel washer features a design that allows it to sit flush against various bore diameters, reducing stress concentration and ensuring even pressure distribution. Constructed from hardened steel with a bare finish, it accommodates variations in bore sizing without the need for multiple fastener sizes, making it versatile for mandrel-mounted applications.
Ideal for engine builders, restoration shops, and serious DIY mechanics, this washer provides OEM-quality performance for crankshaft work and balancer installation. Its stepped geometry creates distinct seating surfaces, making it compatible with drive mandrels that feature shoulders of different diameters.
