ABSTRACT:
The present invention allows for the pack clearance of a clutch pack to be adjusted during the manufacturing process to the proper amount, even if there are variations in friction disc thickness and steel disc thickness. The present invention is an electromagnetic clutch having an adjustable pack clearance arrangement, comprising an output shaft, a pressure plate, and a clutch pack actuated by the pressure plate. The pressure plate and the clutch pack are splined to the output shaft. There is also a clutch housing splined to the clutch pack, which also receives force from the clutch pack when the pressure plate is applied. The pressure plate defines a pack clearance for the clutch pack, and the pack clearance is adjustable by a pack clearance adjusting arrangement.
