ABSTRACT:
A clutch drive mechanism for the cooling fan of an automotive engine includes a driving member rotated by the vehicle engine and a driven member carrying fan blades. The driving member includes an axially movable portion which is rotated through drive pins slidably received in bores in the axially movable portion. Resilient grommets are carried in the walls of the bores and engage the pin to prevent noise and rattling as the clutch members are engaged and disengaged. Grooves are provided on the pins which receive the grommets when the axially movable portion is in the fully disengaged position, which allows the axially movable portion to move to a truly centered position with respect to the spindle, thereby eliminating stress on the components when the mechanism is in the released condition.
