[GreenKeys] Noisy motor - lubrication ?

Mon, 22 Jan 2001 18:20:54 -0500

You need to find out if the bearings were the "sealed bearings" before you
pay heed to that No Grease warning...

the synchronous motors lasted longer than the series governed...
mainly to the lack of the carbon dust from the brushes.

a synchronous motor probably has had the bearings replaced...

If the bearings have been replaced you will probably
find that they are the  "open cage bearing" that needs
to be greased when doing a P.M.

The "oil lube only bearings" died... and were not available to the Army
repair system somewhere around 1975.
