ABSTRACT:
A shipping and installation restraining strap for the output member of a clutch operating hydraulic slave cylinder disposed concentric to an input shaft driving a motor vehicle gearbox from a friction clutch. The output member takes the form of the clutch throw-out bearing, and the restraining strap comprises a generally annular portion attached to the throw-out bearing and a pair of integrally formed strips having a portion of reduced strength terminating in a lug engaged in a T-slot in the slave cylinder casing. The slave cylinder, the conduit connecting the slave cylinder to a master cylinder operated by a clutch mechanical control, and the master cylinder are prefilled with hydraulic fluid prior to shipment to a motor vehicle manufacturer for installation on a motor vehicle. Upon first actuation of the slave cylinder, the strips are broken at their portion of reduced strength such as to permit normal operation of the slave cylinder for actuation of the throw-out bearing. Alternatively, the restraining strap may be formed as a single unit with an integral tubular dust cover surrounding the throw-out bearing carrier, or made integral with the throw-out bearing carrier itself. The restraining strap is preferably made of plastic.
