Abstract
A pulley shaft and stationary pulley assembly for a belt drive mechanism of a continuously variable transmission includes an inner surface of the pulley having metal-cutting serrations, a blocking shoulder, and a surface for engaging a pilot guide surface formed on the shaft. The shaft, formed of softer material than the hardened pulley, includes a shoulder adapted to have serrations formed in it during the assembly process, a hardened pilot guide, and a blocking shoulder adapted to contact the blocking shoulder of the pulley.
