Abstract

A spacing apparatus for use in mounting an engine cooling fan of a racing vehicle to a drive structure, typically the water pump drive shaft, is made from a spacer body to which a fan hub quick-releasably attaches. The spacer body has a base with a shaft extending therefrom having a reduced perimeter section over which the fan hub mounts. When the fan hub is in place, engagement rods may be inserted in the fan hub to retain the fan hub on the shaft. The engagement rods may be easily and quickly removed without risk of burn to the mechanic to allow quick release of the fan hub on which the fan blades are mounted.
