Everything is so professional and casual. You basically show your hands and comment on their work. This is so different from other similar ones, that I even recorded your video in case of need.

Very nice video,which gives clear ideas of servicing any kind of mechanism.

This video is awesome. Thanks for much! It, and your other videos, helped me on my TC-K620, which was a gooey mess. The small belt was so far gone that I even had to take that motor completely off the board because the goo had gotten down to where you oiled the other motor. On mine, there is that tiny retainer ring that must be pried off to get the door detached. It went flying and was lost for a while. Fortunately I remembered how I had the mechanism pointed when I pried it off and carefully searched until I saw it over on the side of a cabinet. The retainer ring on the idler thing under the bottom of the tape cradle was hard to remove, and even harder to put back on without losing it. I found that turning the tweezers to the side and pressing down on it with both prongs works best. But I got the deck working, and actually enjoyed fiddling with it.

Another reason why I love ❤️ this channel ❤️ thanks my friend ❤️

I got the TCK570, belts are on order, but already check your video, it is really insightful, also for a noob mike me. Will let you known what the outcome is once all is done, thanks though for making this video💪👍

Guess what im doing right now... (had to deal with the gooey version) had repaired it earlier with a self made belt from innertube bike :) If your going to fix this same one I recommend you also order the 2 capstans beside the 3 belts.

I don't know what kind of cleaning solution you use, but I have used only Isopropyl alcohol for cleaning such repairs for decades. And only sewing machine oil to lubricate the sliding bearings. It is quite cheap with effective. I have a similar SONY TC-K 661S and it plays great.

Thanks mate! I have bought a Sony Tc-WR870 and i will have to change all the belts and this video give me a first idea of Sony mechanism.

there were two more washers (transparent plastics) in the back plate holding/spacing two capstans. they are easy to lose just be careful.the supply pinch roller needs to be adjusted with a test tape.

thank you for this video, you helped me a lot 😉

Your video is the absolute best! I'm fixing a TC-K677ES, followed the instructions, replaced all the belts as shown, and now eject button works, FF and Rewind work, but when I hit play the heads move up into position but the cassette tape doesn't turn- after a second of trying to play, the player auto-stops like it's reached the end of a tape (but it hasn't). Any idea what could be jamming up the mechanism only when I hit play? thank you for your wonderful video.

You mentioned the middle motor was for fast forward / rewind - I'm just curious, in play mode, is the take-up reel powered by the same motor, or by the capstan motor instead?

Good video 👍

Deriving inspiration and courage from your superb demonstration, I work on my TCK-590, although not exactly the same but mechanisms overlap. Managed to get the belts on and reassemble, repeating the process twice as, for some reason, the cassette holder does not open or close. I do not know what I might have missed, possibly misalignment of the loading cam gear? Thank you for any advice.

Many Thanks!!

I want to ask you a question.

I see you didn't pay attention to the microswitch on the right that detects the opening of the door during assembly. You have to turn the big white gear a little or press the microswitch.

Thanks for the helpful video, I also have TC-K670 and have disassembled the player and the belts seem to be a little bit loose, but they still seem to work when I turn the wheels. I have problem where when I want to play cassette, the motor just makes a whirling sound. Do you think this is fault of the belts?
