I just replaced the belt on my Pioneer CLD 702 after not having used the unit in many, many years (I bought it new in 93). The tray now opens and closes without issue except there seems to be a momentary thud or binding noise when you first click on the Open button. Here is a Vimeo link that illustrates the problem.
