Repair and Diagnosis: Transmission: Clutches: Description

Three types of clutches are used in International Harvester vehicles. Auburn clutches are distinguished by the open cover design. Borg & Beck clutches have a full, or closed, cover and three release fingers. Diaphragm Spring type clutches also have a closed cover, but are distinguished by a dish shaped diaphragm spring which is slotted, thus creating multiple release fingers. Removal and installation of all three types of clutches is similar. Clutch actuation is accomplished through hydraulic system on Motor Home, and Mutli-Stop chassis. All others incorporate a mechanical release system.
