Abstract: A straddle bearing incorporates a U-shaped frame receiving bearings which support an output shaft of a PTO assembly. The bearings flank or straddle a sheave or other drive member which is fixed to the output shaft. Radial loads imposed on the drive member are transmitted to the U-frame as opposed to the clutch and flywheel. The sheave and U-frame are dimensioned to permit replacement of belts or other torque transfer elements without disassembling the U-frame. In addition to being supported on the clutch housing, the U-frame can be supported on a beam and/or a bracket connected to the prime mover frame or a frame of the driven device. The configuration of the U-frame permits adjustment of the orientation of the U-frame with respect to the clutch housing, and also permits the mounting of an auxiliary drive member on the output shaft.
