Abstract
A pin has an end secured to the pressure plate and the pin is disposed within a pressure plate hole for constraining the clutch cover and the pressure plate together for rotation about the rotational axis. A bushing is disposed within the hole and includes a bore for receiving the pin. The pin is received within the bore in an interference fit relationship while the bushing is permitted to move freely within the hole in the clutch cover. The pin moves within the bore in response to an adjustment force to accommodate wear of the clutch friction components. A resilient assembly absorbs vibrational force along the rotational axis to prevent misadjustment of the clutch. The resilient assembly is interposed between the bushing and the pressure plate to prevent the pin from moving along the bore in response to a vibrational force.
