Maintenance Alert (Bearing Lubrication)
Posted: Tue Jan 05, 2010 12:12 pm
If you labor under an assumption that all Shopsmith bearings are sealed and need not be lubricated then you are as wrong as I was.
I was truly surprised today when I discovered yet another motor that has possibly been abused because I have not been oiling it periodically. How did I discover this?
Well, there was a discussion on another thread about replacing bearings and since I have no project in the works I had time to play. I have had a defunct motor (from my old Crafter's Station) sitting in the shop for months and I decided to pull the bearings to see what type they were.
Much to my surprise (again) there are no bearings but rather bushings. Furthermore, there is a lubrication requirement. When I got the bearings partially exposed I discovered that they were square and soppy with oil. Upon further examination I find an oiling port. Not hard to see just easy not to notice (which I have done for many years).
The alert: These same oiling ports exist on the Power Station. So, at least the Crafter's Station and the Power Station motors require some periodic oiling.

A cotton like material just soaked with oil and packed in around the "bushing"

Nothing Special

The square bearing

The whole mess
Now I am trying to pull the external cover off one end of the motor to get a look at the inside of the square bearing.
I would advise that you check all of your motors to see if they have oil application ports.
