Clutches - Diaphragm Spring: Description

Single plate dry disc type with a diaphragm spring replacing conventional clutch release springs and release levers. Diaphragm spring is shaped like a dished washer, with inner rim slotted to form many release fingers, and is pivoted on inner and outer pivot rings mounted in clutch cover. Most models have straight release fingers, however some models have 6 or all of the release fingers bent upward to provide centrifugal action for increased clutch pressure at higher speeds. Models having 6 fingers bent upwards also have weights on these 6 fingers.
