Abstract
Methods and apparatus are disclosed for retaining components in a downhole motor in the event of a mechanical separation or failure of one or more components therein. As described, the retention mechanism does not require a threaded connection to components of the mud motor drivetrain. Downhole motor assemblies including the new catch mechanism also include a structural element to engage the catch assembly and the components to which it is attached in the event of a mechanical failure within the mud motor assembly.
