Abstract
A viscous clutch includes an input member, an output member, a working chamber defined between the input member and the output member, a reservoir to hold a supply of a shear fluid fluidically connected to the working chamber by a fluid circuit, a valve that is electromagnetically actuatable to selectively control a flow of the shear fluid along the fluid circuit, a control coil assembly, and a securing mechanism. The control coil assembly includes a modular center hub removably attached to the input member, an electromagnetic coil and a coil bearing rotatably supporting the electromagnetic coil on the modular center hub. The securing mechanism is removably attached to the input member radially inward of the working chamber and the reservoir, and includes a radially outwardly extending flange.
