Abstract: A fluid coupling device and fan mounting arrangement is disclosed. The fan is of the type having a hub portion and a plurality of fan blades integrally molded therewith from a plastic material and an annular spider having its outer periphery attached to the hub portion and a plurality of inwardly extending tabs bolted to bolt bosses projecting forwardly from the front surface of the output coupling member. The bolt bosses define a bolt circle having a radius R.sub.1 and the output coupling member includes a plurality of pilot portions defining a pilot diameter of radius R.sub.2, wherein R.sub.2 is greater than R.sub.1. The annular spider includes a plurality of inwardly extending pilot tabs, each of which engages the outer periphery of one of the pilot portions of the output member.
