Intermitant motors should be replaced. From experience, relays and transformers rarely go out. It is usually the motor that burns out and it usually does so quickly when at life's end.

A motor can last for as long as you want it, or it can self-destruct before your eyes while there is still break-in oil in the fuel. I believe it all comes down to how well you maintain the motor, how you use it, its mechanical genes and a bit of luck.
