auto tanner slipping

[Adrian]

    My auto tanner drum is slipping back somehow in the motor and not revolving like it should.
 Has anybody else had this problem and if so can it be fixed without the purchase of a new motor? Thank,s.

Look at the drive cog on the end of the motor shaft or the one on the tank shaft.
They both have small set screws to hold them tight to the shaft; sounds like one of the set screws has backed out.
