Maybe the bearing needs lubrication in my XXX. Anyone know how to do that? Jon |

If you look at the rear bearing you will notice a cap over the bearing held on with two screws. If you unscrew the two screws the cap will come off and you can add grease to the bearing. The front bearing is the same BUT you will have to take off the fans. To get the fans off you will notice three screws along the edge of the fan housing, they hold the fan housing covers in place. You unscrew those three screws to get the fan covers off (don't lose the small nuts at the end of the screw). Once you get the top cover off you have access to the first fan. Wrap something around the fan and take the nut off the end of the armature shaft. You can then take off the fan, remove the lower cover, take off the second fan and gain access to the front bearing. You will see the same two screws as on the rear bearing cover. Once you take off this cover you can add grease to the front bearing. When you reassemble the two screws screw into the cover on the other side of the bearing. Then just put everything back in reverse order of taking it off.
Lower fan, lower fan cover, upper fan, upper fan cover, the three screws and the small nuts that hold the covers in place. Hope that helps. |

After decades, the carbon brushes become stuck in the shunts and the spring doesn't move the brush out to the commutator correctly. Simply remove the carbon brush from the holder and clean the shunt with a q-tip dipped in alcohol. Get all the carbon dust from the shunt. That's what's wrong with your model S. At the same time, grease the front bearing.
When you replace the motor brushes, be sure to use a commutator seating stone to seat the brushes back as well as clean the commutator. It only takes a moment holding the seating stone against the rotating commutator. Cleans and brightens it back up. As far as the bearings, you add grease to the balls. Remove the bearing 'shield' for access to the balls of the bearing race. Some bearings have metal caps on both sides, which means you cannot grease the bearing. New bearings are still available if you find yourself with bearings that have metal shields. New bearings have vinyl shields which come off be prying at the edge with the tip of a razor knife. High Temp bearing grease, like for automobile wheel bearings is obtainable at an auto parts store in a pound can for a small amount of money. |
