A viscous clutch (') includes a rotor (), a housing () that at least partially surrounds the rotor, a center shaft () rotationally fixed to the housing, a mounting disk () rotationally fixed to the rotor, a working chamber () defined between the rotor and the housing, a reservoir () for holding a supply of shear fluid, an electromagnet (), a valve assembly () to selectively control flow of the shear fluid between the reservoir and the working chamber, and a flux guide () operatively positioned between the electromagnet and the armature. At least a portion of the mounting disk extends outside the housing. The valve assembly including an armature (-) that is selectively movable in response to magnetic flux generated by the electromagnet, and the magnetic flux is transmitted between the armature and the electromagnet along a flux circuit. The flux guide extends through the mounting disk.
