Abstract: A clutch brake assembly is provided for operatively connecting to a rotatable shaft. The clutch brake comprises at least two arcuate members, each having first and second ends, and inwardly extending tabs for engaging standard grooves in the shaft. The clutch brake further includes a first fastener for pivotally coupling the first ends and a second fastener for connecting the second ends of the arcuate members to form an annular assembly about the shaft. The arcuate members may be preassembled such that they are pivotally coupled at their first ends prior to installation. During installation of the clutch brake around the shaft, the first arcuate member is installed around the shaft and the second arcuate member is then pivoted toward the shaft in a plane substantially perpendicular to the axis of the shaft. The second fastener is then installed.
