Grease: I know this is a old post and still people need to know what has worked well for some of us that have been doing repairs for a long time.
I have used a product that I bought at a hardware store and then having nothing but good results over years combined with no negative side effects I have come to use Lubriplate 105 from a 10 Oz tube that is kept in a plastic film container on the bench. Over the years, I have never had a single deck come back to me with the problem being caused by a failure of the grease used. Not one. In addition I cam across an oil that I was at the time trying to get rid of. O put it in the motors or a A2000R test case deck- what happened? I had to wipe my eyes and check all my connections but a deck previously able to get down to a wow and flutter of say .07 to .06% was now reading .02% with AMS Signature series 0W30 motor oil which is a synthetic oil. You can use three in one if you like but I know what oil I will use and I continue to use it to this day.
