Abstract
A bolt and keeper assembly including a crimper for crimping a portion of the keeper into pockets formed in an upper portion of the bolt head are described. The crimper includes a hydraulic cylinder for carrying hydraulic fluid under pressure and a crimper body having a bore extending therethrough. The bore has first and second end portions and an intermediate portion extending between the first and second end portions. The first end portion of the crimper body bore is configured to receive an end portion of the hydraulic cylinder, and the second portion of the crimper body bore is configured to receive at a least a portion of the bolt head and keeper assembly. When assembled, an upper portion of the bolt head and keeper assembly extends into the intermediate bore portion. A compressible ring is positioned in the intermediate portion of the crimper body bore at a location to engage the keeper and for crimping sections of the keeper into the bolt head pockets.
