Abstract
A rotating clutch assembly has an apply piston, a backing plate, drivingly connected with a rotatable shaft, and a plurality of friction plates spaced between the piston and the backing plate. The backing plate is limited in axial movement along the shaft by a pair of locating rings. One ring is secured in a groove on the shaft and the other is secured in a groove on the backing plate. The backing plate has a axially extending wall that overlaps the one ring to prevent centrifugal escape from the groove. During assembly, the backing plate and friction plates are urged in an axial direction against the piston to provide sufficient space to install the one locating ring; and then the backing plate is urged in the other axial direction to provide space to install the other locating ring.
