[ARC5] Dynamotor Maintenance

[Robert Eleazer]

I note that the manual for the BC-312, et al, says that the DM-21 dynamotor bearings should only be lubricated by One Drop of light oil at the end of 500 hours of operation.

Shucks, I washed out the old grease in the bearings in one of my DM-21's with spray lube, picked out the hardened remains with a screwdriver, and then repacked it with aircraft magneto grease.  I guess I probably voided the warranty....
