Abstract: An assembly for retaining a pin in aligned bores of two structural members, such as clevis and a tang, includes a support member or boss, a retaining flag and a retaining pin. The retaining flag is slidably mounted on the support member and may be moved between a service position wherein the pin may be inserted into and removed from the bores and a locking position wherein the pin is held in the bores, preferably locked from rotation. The flag includes an opening having engagement surfaces for contacting a groove in the pin in the locking position. The flag is held on the support member by abutment surfaces. Two abutment surfaces serve to guide the flag in its sliding motion between the service and locked positions. Other abutment surfaces maintain the flag on the support member and prevent removal of the flag. The abutment surfaces contact the retaining pin in the locking position to maintain the flag in the locking position.

Abstract: The stabilizer, in a preferred embodiment thereof, comprises a generally tubular body which is axially slit, as in the prior art. According to one practice of the invention, the surfaces of the body immediately adjacent to the slit have ribs formed thereon which define bearing surfaces for clamping together, to draw the surfaces into proximity, narrowing the slit, thereby to contract the stabilizer to a constrained dimension approximately eight percent smaller than its free dimension. This is done to facilitate its insertion into an undersized bore. The novel method, then, in an embodiment thereof, comprises contracting an axially slit friction rock stabilizer by engaging the aforesaid ribs (formed thereon) with a tool, to contract the stabilizer to a reduced and constrained, approximately eight percent smaller, cross-sectional dimension, inserting the stabilizer into an undersized bore, and withdrawing the tool.
