I own a similar deck and I noticed there are three plastic poles close to the motor pulley where you can nicely place your flat belt before you assemble the mechanism. Same thing happens to the small pulley (two white plastic clips / poles up the gears pair). The very first time I opened the mechanism in order to change the belts I scratched my head questioning what to do until I watched a YT vid. About the small white gears I noticed a small crack on the lesser gear that made the whole mechanism went "berserk" (I mean rewinding the tape very fast but in the wrong way, trapped door, savage speed changes, strange alarming harsh noises, chewed up tapes, etc.). That little demon is the culprit of almost anything going wrong on these kinds of advanced Sony decks.

I did belts on a TC-KB820 which looks very similar. You can do the belts w/o removing the print board but the centre screw does need to come out. You also need to make sure the cog and pegs on the reel motor are in the correct position when reassembling. I also found the head on the one I did pushed over. Owner tried to force a cassette in with the head bridge in the up position (due to belt failure). Azimuth was seriously out after that.

This was an entry-level 3-header. They were all plastic machines - across the whole spectrum of manufacturers. I recently had to re-belt a Kenwood KX-7050S. It's a freaking nightmare with these machines that have the mechanisms attached to the faceplate subframe. Plus, the whole mechanism has to be disassembled to get to the capstan belt. And while doing that, it's almost impossible to not break one of those extremely tiny solder joints on the Mabuchi motors or the cassette compartment's microswitches ... because it just has to be motorized 😡

I was debating taking a soldering gun and heating the plastic to reform it, but decided against it. Gently bent the arm back anticipating a snap, but I got lucky without heat.

It's like the reverse mechanism is clicking and trying engage, but it's just not getting there. And, it's happening on Both Decks. Regular one sided play seems to work fine. Is there a common part on the main board for that function?? Or did both decks fail the same way?

To my knowledge Dolby S is supposed to be the best consumer Dolby ever conceived, hardly distinguishable from CD (even with type 1), However the head(s) must be squeaky clean, azimuth spot on and a pristine head condition (not worn away). In my experience Dolby B and Dolby C are just as sensitive to these adjustments. Especially if the tape is played in other machines. If the azimuth is off even a little it will sound as if you put pillows over your ears, not to mention and the breathing you'll hear (especially with Dolby C). Many don't like Dolby because in their mind it cuts the trebles, with the way Dolby works it records the trebles at a higher than normal level so it is perceived it cuts the highs when infact it is actually restored back to the normal level of treble sound, however the Dolby circuitry is a bit sensitive to the azimuth even on the same machine the phase difference can confuse the Dolby circuits. Sounds fine with no Dolby but even on the same deck if the azimuth is out badly Dolby will make everything sound awful, even on the same machine.
