How to Repair / Change Belts & Pinch Roller on a Sony TCK511S tape Deck 

My 20 year old Sony deck is playing again, thanks! Replacement of belts and pinch roller was easy with this instruction.

The video is well-made, but unfortunately, it doesn't address a common real issue with this Sony mechanism. The main problem with this mechanism is the small 17-tooth gear attached to the assist motor, which has a tendency to become loose on the spindle due to cracks. I've encountered this issue at least seven times and had to replace the gear each time. Another noteworthy point is that the video makes an ambitious move by reassembling everything without thoroughly verifying if the problem has been fixed. While I believe the author may have done this behind the scenes, it's important to mention, especially for newcomers like me. Thank you for the informative video and the verbal comments. I'm excited to see more from you in the future. I've also liked and subscribed to your channel!

I am going to tackle my Technics RS-DV280 twin tape deck.Hopefully the record deck will work as it did when i bought the hi-fi 20 years ago.Pinch roller's and drive belts.Many thanks for your helpful video.

Great video, very helpful. Just one thing: you do not need to remove the pinch holder. The pinch roller can easily be removed with a screw driver by inserting the screw driver from the pinch roller (right hand side) and press to the bottom. This works like a lever. Then you just have to press the new pinch roller with its pin carefully into the little slots with your finger. The pin must snap securely into the slots. If the belts are ok and only the pinch roller has to be replaced you can do it without opening the tape deck.

Thank you for this very helpful video. I got a Sony TC-KE300 for 5 bucks. New belts and a good clean of the capstan and it is O.K. to go. Perhaps I have to replace the pinch roller, but that’s it. These plastic bombers are so underrated! This machine is so easy to maintain, it‘s a joy. It‘s a Sony.

Thanks for such a great demonstration! 💖

Thumbs up😂 the first video where the grey gear wheel and it's position is mentioned. If you change belts and it is in the wrong position, the deck won't play😂😂

Very clear, thank you for sharing your expertise. Everything working now.

Mine is the 561 I have done belts an pinch roller but previous owner for some unknown reason took screws for the cassette heads out and head height and alignment are the main problems now I have fixed all other faults,head height is the main one I am having problems with .I also found lots of dry joints on mine the transistors at the back and audio ins and outs and sound suppression caps needed to be replaced as one was leaking.

Great video, very comprehensive

this helped me a lot. Thank you ❤

Thank you so much, this helped me big time!

Thank you so much for the video ! ! Helped me a lot ! !

A very detailed repair video , thanks. Do you have a preferred supplier for belts and rollers here in the UK?

great video - thank U, my TCK 511s needs new belts 😁😁😁😁

What do you charge to do this? I have a TC-K511s. I'm based in Liverpool.

Hi, Do you service repair? Regards Dave

I have a tc-k411, bought in 90s as a new device. I replaced the belts and it works but there is another problem that remains from the start. The mechanism damages the tape from time to time. The damage looks like a fold, parallel to the tape edge. I made a workaround: a simple circiut that makes the motor to apply less force to the tape while playing and maintain the full force while rewinding forward, but this is only workaround. What can cause such a behavior? Something bent, or bad mounted? Erasing head too high?

could you please share the size of the belt? thanks

danke

Just watched this video after doing a search for belt replacement and got a lot of good tips on making the job easier. I have a Sony TC-K561S (US model TC-KA1ES) which looks similar to this deck, and a Technics RS-TR575 which both need the belts changed. Do you know if the Sony is the same as this one as far as repairs? They also have said that the Technics needs to have the motor connectors unsoldered from the top PCB to get to the belts. Have you ever done the job on that particular deck as well? I fear there’s no other way to access those belts unless you can use a belt hook pull/push tool. Thanks and keep the great videos coming. They’re so helpful for the do-it-yourselfer like me trying to avoid tossing old decks when you can replace simple parts.

One of my tapes snapped. Does that mean I have to replace the pinch rollers?

I followed all of your instructions and when I press play it spins the rapes really fast with no sound. Please help
