Abstract
A retaining device or snap-ring for retaining a mating hub and drum within a transmission is provided. The device is insertable into a groove along the inner circumference of a circular flange and includes a main outer loop, an opening for dividing the snap-ring into two deflectable curvilinear portions and at least partially defined by a tabular extension projecting from each curvilinear member. The tabular extensions provide sufficient surface area for applying deflective or compressive force to the snap-ring and are contoured to facilitate use of a deflection tool. The snap-ring further comprises an externally-projecting secondary loop for reducing deflection force, or an internally-projecting secondary loop for increasing deflection force. The snap-ring may be used within a double-flange hub having a plurality of slots for facilitating insertion of the secondary loop and the tabular extensions within the flange groove.
