Maintenance Alert (Bearing Lubrication)

[dusty]

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.

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.

As always, it is important to read the manual (I sure had not). From the Crafter's Station Manual:
"The motor needs lubricating. You should oil the motor according to the directions on the motor label. If your label is missing or unreadable oil your motor after every 50 hours of use with approximately 1 tsp. of SAE 20.
1. Remove a yellow plug from each end of the motor.
2. Place appropriate amount of oil in holes.
3. Re-insert yellow plugs."
My Power Station manual indicates that NO lubrication is necessary. Though I will inspect the motor the next opportunity I have. Hope this helps.

I worked up a "table" showing all of my Shopsmith Tools along with maintenance schedules. Most of the maintenance is quarterly. If you would like, I can scan and send you this table.

I have this "table" posted on the wall and have found this extremely helpful in keeping the maintenance up to date.

Trouble is, I am working on a, new to me, shop. So, everything else is currently sidelined.

That would be appreciated, attach as a pdf - Please!

I would very much appreciate having such a chart.

Wow I would love to have a copy of your table. Thank you in advance. Jim

Please count me in too!

I would love to have one. I don't have a system. Dusty, I assume that this is not true of the Mark V Motor. Am I safe in that assumption.

You are correct in that assumption. The Mark V motor has bearings. As far as I know it is only this one motor, used in the Power Station and Crafter's Station, that has this bushing arrangement and I don't know that that is universally true.
