(b) External-type rings must be expanded only enough to permit installation without becoming bent.
(2) After installation, make sure that each retaining ring is fully seated in its groove, without looseness or distortion.
(3) Distorted retaining rings must be replaced.
B. Installation of the Retaining Rings
(1) Procedure - Plain retaining rings
(a) Plain retaining rings can contain slightly rounded edges on one side and sharp edges on the opposite side. The slight rounding, caused by the stamping die, is not a bevel, and the ring must not be classified as a beveled ring.
(b) Plain retaining rings must be installed only in square sided grooves. When one side of a plain ring has visibly sharper corners, this side must be installed away from the detail part being retained, so that the sharp-edged side thrusts against the groove.
(2) Procedure - Beveled retaining rings
(a) Beveled retaining rings have the added function of taking up end play in the detail part being retained. This type of ring has a definite 15 degree-bevel on one side designed to fit a corresponding bevel on the side of the groove away from the part being retained.
(b) Beveled retaining rings should be used only in correspondingly beveled grooves. These rings should be installed with the flat side of the ring toward the detail part being retained.
