PL-112D internal skipping noise

Postby MrsBettes » 13 Oct 2017 05:43

My PL-112D started making a loud internal skipping/scratching noise. Can anyone please help me, by telling me what it could be?? It also used to make a thumping noise through the audio but as of right now that is not my concern unless they are related. I don't know that much about the mechanics but thought I would reach out here first.

Pay attention to the condition of the ball . It is located in the shaft bearing drive . If the ball is damaged, it can cause knocking , clicking and other sounds . Carefully inspect the ball through a magnifying lens . On my PL-12D ball was worn out and needed replacement . Also - read this blog . Very useful to know - http://mr-ives.blogspot.ru/2013/07/rest ... table.html

Are you sure that the platter is not "rubbing" against the top plate?

I actually have a 112D (now my back up) and I had to adjust the suspension on it to level it and keep the platter from contacting the top plate

Also, in wouldn't hurt to also examine and re-lube the spindle bearing and the aforementioned ball. It's stupid simple to remove and lube it on the 112D :)

BTW......
A basic rule of thumb with any belt driven TT is, when you remove the belt and give the platter a good spin by hand , it should continue to spin for about 2 minutes before coming to a complete stop.
This is with a well lubed bearing in good shape .

This is also good way to do some trouble shooting for issues such as yours. :)
