Hello,
My old belt being in several pieces, I didn't know how to install the new one; So, after removing the plate, I unscrewed the white plastic gear located near the shaft, although it wasn't necessary; now, I can put it back, but as soon as I power on the board, the plate spins and doesn't stop. I can't see what I'm doing wrong?
Thank you for your help

Yes, I saw the photos, they are indeed very clear, they have a thunderous resolution of Zeus from the dead!!!
So, if I understand correctly, the hole next to the gear (photo 9589) is supposed to receive the axis of the plate.
In photo 9592, we can see the switch I was talking about (in yellow).
It is controlled by the articulated lever (on the right) and is activated by the long plastic piece that is moved in length by the cam of the gear located inside.
Without going into too much detail, the plate must have a pinion that drives the gear, then this gear stops when there are no more teeth to catch on the pinion.
This resting position corresponds to reading (or stopping). At the end of the arm's travel, something activates the arm's return mechanism (this brings the gear into contact with the pinion, and the gear makes a full turn back to the resting position (no more teeth).
The starting and stopping of the motor must be triggered by the position of the arm (outside the disk; between the start of the disk and the resting position of the arm).
So I think that by turning the plate, even by hand, it should turn the gear until the end of the teeth and finalize the return of the arm.
At rest, if you bring the arm above the disk (while keeping it raised!), it should start the motor (plate). If you lower the arm, the motor should stop.

Hello
There was certainly a switch related to this mechanism that you didn't put back in place properly.
Try posting a photo, maybe we'll see something that needs to be moved...

Good call! Congratulations on your keen diagnosis, because I didn't see that little switch; In fact, a small plastic screw was broken with a piece left inside the threading, I put some glue on it and it seems to hold.
In any case, a big thank you, I will be able to play some old vinyl records for my grandson.
Thanks again and have a great weekend.

I got a Scott PS 28 turntable and I want to replace the belt! Does anyone have a diagram for the installation? Where exactly does the belt go? It’s fragile and I don’t want to damage it! Thank you for your responses!
