So I hate publicly saying I fixed something, because that usually means it comes right back - but I think I fixed it. Got a call today from Dago at UNIS while I was at work so we couldn't talk long, but he suggested I try the steps outlined in the manual for tightening the belts. Just thought I would share some photos as I bumbled through this...
Before removing the square frame you will need to unplug the LED lights. The plug for these is accessed under the player 1 control panel. It's a little difficult to see in the manual, so I included another photo. (Access it in player 1's left corner after removing the player 1 control panel.)
So as illustrated in the manual, there are five different spots where you can screw on one of two adjust plates (these are included as extras in a small box shipped under the table). I'm not sure why only two extra plates are provided if there are five spots. I'm also not sure why only one set of screws are provided as it makes the other plate rather useless when there are no screws for it. And I'm definitely not sure why one plate is plate A and another is plate B with separate part numbers when they both look identical! Anyways, the next three photos show red circles for potential spots to attach the plates.
Photo #5 shows where I attached the plate first. (EDIT: I found out later I installed the pin upside down in the photo. Make sure the pin is facing DOWN to press into the belt.) Like I said, with five potential spots to choose from, this was a pure guess. So I decided to play a game with the hood up, so to speak, to see if there were any issues.
Before starting a game like this, I recommend securing the cable used for the table's scoreboard so it doesn't get damaged by all the moving parts inside. (Photo 6.)
Things seemed fine for about three games, then I heard that awful sound I had heard before. It happened a few more times but it didn't look like things were actually colliding with each other. It just looked like maybe one of the belts was briefly coming off one of the wheels, and then the mechanism sliding back and forth shakes loudly as it briefly gets off track.
So I removed the adjust plate (remember - I only have one set of screws!) and retightened it in photo 7 on a track close to the player 1 side which I thought could be the culprit. (EDIT: Again - it's upside down in the photo. Make sure the pin is facing DOWN.) That might have been all there was to do. I played well over a dozen games after that (with the playfield still removed) and never had another incident.
The paddle/ball pieces are easy enough to put back in their spots as the magnets grip them instantly. I did notice however each piece has a side marked with a line on it. Wasn't sure if there was a particular side this should be facing and didn't notice it before I removed them. I first tried it with the line facing away from me and the ball hit the paddle and sent it flying across the playfield! Switched it around so the line was facing toward me and it didn't happen again, so hopefully that was the problem.
My only other question is how quiet should the movement mechanism be with the glass on? I can definitely hear machinery whizzing back and forth like a giant printer. I assume that's normal as it has always been like that, but I'm curious if this is the same experience as with others.
