I have a TESLA NC430 turntable, belt drive with the chassis HC43. In time I had to clean it from time to time and today I used a micro mechanics spray for lubricating the mechanics. It work pretty good, but the bad part is that now the arm lift falls down to quickly and after fullstop it is thrown quickly. The arm lift had a cream vaseline before and I think that this is the cause of being thrown so quick. I even tried to calibrate the screws but without any results. Can somebody help me in this problem? Which vaseline should I use? The vaseline worked for about 30 years without any problems.

It needs more friction. In the shop, we use either lithium grease, or if it's a "dashpot" type, SAE 2000 silicone differential gear oil from a hobby store.

Cheers!
