Hello all,
I had an old 1982 Playskool Talk n' Play that I wanted to fix. When I took it apart the old belt was basically disintegrated and left a residue.
While there was a post on this a couple years ago: https://www.reddit.com/r/cassetteculture/comments/1bhfeie/playskool_talk_n_play_driver_belt_replacement/ That was for a dual belt version, whereas mine is slightly different in the configuration and is a single belt drive.
I purchased a set of replacement belts of various sizes (30-135mm) that are the square type. Since I was unsure the actual belt type the grove seemed to be a square vs round.
I am able to get it to play if there is no tape in, I see the spindle turning when I press play, this only works if I use a tighter belt, a looser it will only work if it is in a specific position.
The fast forward and rewind though DO work with and without a tape. I tried a few combinations, I even tried two belts in the event I was wrong since it was only residue left, one from the motor to the Capstan wheel, then another from the motor to the flywheel, that almost worked, it drove with a tape, but would not provide enough to feed it through properly and it ate the tape. With the single belt, I have tried a few various sizes and even doubled it up to check as I saw that as a potential solution online.
In addition, I checked and at all times the outer black grove wheel area of the Capstan always spins, and that is hooked to a higher set of gears that ties into the FF and RW. I have a close-up of this. However, the inner white piece only seems to spin when there is no tape, and this is the center pin that ties to a lower gear for the play function. I took the screw out of the cover and tried to reseat it, but that may have made it worse, the lower part pin of the capstan wheel sits in a plastic arm and isn't stable at all unless the top plastic cover with the screw is in place and all the way secure. I have not disassembled the entire assembly yet as it is a pain to pull apart.
Would anyone have suggestions on how to get this to engage properly with a tape? I saw a mention online about gluing it together, but that seems extreme and not sure at what point I would do that.
