Nice step-by-step, but he does make a critical error at around 30:30
when he greases the screw threads. Lubricating the thread will make
the chuck feel springy and cause it to release too easily. If you find
the chuck releases when backing out a tap while power tapping (for a
reasonable size tap), oil or grease on that thread is likely the
problem.

The last page of this catalog has the short version of the repair
procedure.
