OLD REK-O-KUT TURNTABLE STARTS SLOW, TAKES LONG TIME TO COME UP TO SPEED
This problem has been common with the old machines with 4 pole
motors, but it could happen with the upgrad "H" Rek-O-Kuts. They would start
very slow. If you let it run for 30 minutes, it would come up to speed. If you
turned it off an on, it would be fine. Let it sit for a day or two and it would
react almost the same. The problem ended up being the old lubrication, or
possibly old relubrication oil. It had turned into an almost glue. One could try
relubricating, and that might help for week.
The cure is usually to take the motor apart and clean every bearing surface, which is often impossible because of a pressed on pulley. You might only clean the bottom bearing.
Flushing the bearing via the oiling tubes is another answer. If no filler tubes, you'll have to improvise. Ronsonal is a great solvent for that purpose. Squirt it into tubes generously. Cleaning is messy; you need lots of newspaper underneath while you flush, flush, flush. When the fluid dripping out of the motor looks fairly clear, it may be ready for new oil. Let it dry out for half an hour, then add a few drops to the filler tubes. Turbine Oil sold by Grainger has been found quire good for this purpose.
