I have several Mark VII dryers of varying age, the oldest ones being 14 yrs. old. I've never had the first bearing or motor issue from any of them. I grease them on the "NEVER" schedule. None of them has ever been greased.
It won't say on the motor. It will say in the data sheet. You'd have to find the one specific to your brand of motor and follow the greasing schedule as well as the correct procedure. It should be as simple as looking at the brand and using Google.
