PULLEY WITH INTEGRAL HUB CONSTRUCTION Abstract of the Disclosure A pulley (40,140,240) having an axially extending annular belt engaging wall construction (42,142,242) including an axial wall portion (44,144,146,244,246) formed of sheet metal. The sheet metal also forms a circular wall portion (52,152,252) integral at one end with the axial wall portion and extending radially inwardly and axially inwardly with respect to the one end of the axial wall portion. The circular wall portion has an annular bend in an intermediate annular area thereof (54,154,254) and extends therefrom generally radially inwardly to a hub construction (56,156,256). The entire hub construction is formed integrally from the sheet metal into a cylindrical wall structure (58,158,258) extending axially outwardly from the circular wall portion. The cylindrical wall structure has an axial extent greater than the diameter of a shaft engaging interior cylindrical surface thereof (60,160,164). The axially outward end of the cylindrical wall structure provides an integral radially outwardly extending annular lip (64,166,270) suitable to be operatively engaged by a pulling tool for removing the interior cylindrical surface from engagement with a shaft on which it has been engaged.
