…..Excellent, especially the speed adjustment, I was at a loss, as the normal back of motor adjustment didn’t work, thank you tons….. for this I use a cassette tape with a keyboard tone recorded in G played back to an old fashioned guitar tuner with a moving needle, works a treat…..of course this cassette test tape was recorded on a known correct speed recorder…..thanks again.
Very many thanks for taking the time and going to the trouble of making this video. Without it, my machine would have been scrap. As it was, these clear step-by-step instructions and clear video enabled me to to the job in less than an hour (helped enormously by the man at Miratv in Bromley, Kent, who allowed me to pick up the drive belts rather than wait for them to arrive in the post). I would have had a clue how to do this job without this video. Brilliant.
Thank you Graham, I am about to do this to my Sony TC-KE400s deck myself, and this video will be most helpful. Very well explained and covered. Thank you again. Andrew
Yet another KE400S saved! Thank you for making the process of changing belts so easy to follow. Even taking time to show re-assembly. So easy and so quick. Also thanks to Ian Moore for suggesting Thakker's as a reliable belt source in the comments.
Graham, I want to add my thanks for your simple, clear and concise instructions. Thanks to you my Sony deck is playing perfectly again. You really should do some more instructional videos - you have perfect presentation skills.
Absolutely brilliant video. The eject mechanism on my Sony TC KE230 kept jamming, and thanks to your video and some £8 new belts, it is now working perfectly and sounding better than ever. Really glad that it kept the machine out of a landfill. Thanks for taking the time to give such a clear and well constructed step by step, much appreciated!
Many thanks, Graham. In the process of changing the belts in a Sony TC-KA1ES, I managed to knock the cam gear out of alignment. Yours is the only video anywhere that shows what the proper alignment should be before the belts go back on. You saved me -- now I can enjoy all my old tapes from decades ago.
Thank you Graham for this perfect video. I got yesterday this tapedeck for free and disassembled it before seeing your video. Not very difficult. I took away even the mainboard to clean the complete case deeply. Was quiet dirty. The belts have been rotten. How you have shown to position the belts when reassembling will be very helpful for me too. Next week I will get the belts and hopefully everything will be fine at the end.
Dear Sir Graham Nunn, thank you very much for your excellent, and almost “providential”, tutorial in order to let me change the belts of my cassette deck Sony TC-KE300 (same family of tape readers). I have followed your procedure, step by step, with a real success, what would never have been possible for me without your instructions. Thanks a lot also for your tip of fine tuning of the speed. As said by Thomas Peng, “I can enjoy again all my old tapes from decades ago” Luc.
My Sony cassette deck does not turn anymore. I did not think I could repair it myself, but with this video, which is really very well done and very educational, I will try!
Definitely helpful, thank you for posting! Very well shot and not rushed. I'm very glad I watched this before replacing the belts on my KE500S. Cheers from Chicago!
I have exactly the same kind of problem. It existed since I bought a brand new deck from Best Buy store in Chicago. When I tried to use it the first time after I bought it, it didn't work and it was past its warranty period, and I never used it since, always promising myself to take it one day to the repair shop... That never happened and now, thanks to this formidable video. I'm going to attempt to fix it by myself. Good luck to me...
Many thanks, Graham. This instruction video is absolutely brilliant! I have replaced two belts of my Sony TC-KE300 without any problem. My tapedeck is playing excellent again. Cheers from Holland.
Just to thank you for the time and effort you delivered in the making of this video. It was of great help to me servicing successfully a Sony TC-KE230. Cheers!
Thank you so much for this excellent video.I followed your very clear and concise instructions and had complete success. Having revived the deck I am amazed at how good it sounds. Bring back the Cassette! Thanks again
Thank you Graham. My TC-KE400S has differently configured motherboard and daughterboard. My unit appears to be two years older than yours, from the printed date. Your video was very helpful and I'll be ordering replacement belts, rather than spending out on a new unit. Big 'thumbs up' to you. : )
My TC-K615S has been giving me FITS. Your video helped me see that my drive belt cog mechanism is spinning freely. It isn't catching on either of the 2 stop peg positions. I have a feeling this is my issue...or one of them...either way, your video has helped immensely in keeping me on the right track. Thank you!
Just wanted to say a big thank you for such a clear precise tutorial which also worked for the TC-KE200 and all for the price of a £12 set of drive belts from Thakker in Germany. Thanks again 👍
Great video. It helped my replace my belts on my deck. Plus I wouldn’t have know you had to adjust the play speed using the trims on the circuit board rather than on the motor itself unless you said.
Thank you for your hard work and effort , I have the very same deck and can now service with confidence and limited brain power which is something I lack ! Again thank you Sir !!
super helpful thank you! one of gears on the drive side wasn't aligned afterwards and it was causing the tape to run off the cassette, took a while to figure out, good to check these are aligned before butting the top case on!
Huge thanks Graham. I have the TC-KE500S and was able to bring it back to life due to your video. The large belt had snapped and the small one had lost its elasticity. The 500S is a bit different when it comes to teardown and rebuild (a lot more wires) but the drive mechanism is the same. Was able to find new belts on eBay for $17 - including shipping from Portugal to the USA.
That certainly was helpful! I hope your instructions are going to be working for my K415 as well, but I assume so. Thank you very much for your effort, almost 3 years ago...
THANK YOU THANK YOU THANK YOU, I HAVE THE SAME TRANSPORT ASSEMBLY FOR MY TC-WR635S, I SPEND THE LAST WEEK TRYING TO FIGURE OUT HOW TO GET AT IT AND DIDNT THINK TO LOOK BEHIND IT.
Great video, thanks. Looks like the mechanism is the same as in my TC-KB820S - I was wondering how to get to those belts and now I know. My belts feel a bit slack and I'm getting noticeable wow and flutter so I'm going to get some new ones in there. Your video has helped, many thanks.
Great video - followed instructions carefully, old belts were complete gum. Replaced belts and now tape turns but no output at all!! Any suggestions appreciated!
Great video. Just fixed my WE-605 Sony. Belts were tar. Another guy showed the newer dual deck belt replacement. You showed in perfectly communicated detail, how to disconnect the electronics, without destroying them. This is not a detail that you should just start pulling on things to see how they come out. Nope......Kudos! Perfectly taught and great detail...... Stay safe, Dave
After watching this video (and one other one) I felt it was worth giving is a go. I ordered a set of belts from eBay for £10 This evening I replaced the belts on my Sony TC-KE400S and it appears to be working perfectly. It seems that Hazel O'Connor "Breaking Glass" tape that I bought from eBay was dodgy all along, it's still laying up :-( Now I have a fully working TC-KE400S, thank you. one point that may confuse some, is the tape speed adjustment, I know the video tells us not to touch the speed adjustment pots but I wonder how many people turned those pots? From experience (back in the 90's) I decided to turn some pots to boost the output on a Marantz tape deck = I ruined it :-( My Sony deck is now working, thank you. I really appreciate you taking the time to record and share your knowledge with us.....
I just picked up one of these from eBay and it has a knocking sound during playback, so I will be using this video to help understand how to look inside. Thank you!
You could connect it to the line or microphone input of a computer and use "wfgui" that will show the frequency (if using a test tape) and the wow and flutter. Not as precise as an oscilloscope, but it gets the job done.
nice video ..Tip :for speed calibration you can use you Phone with a programm called Sound Spectrum Analyser.. you just have to create a test audio cassette with different test tones on a callibrated cassettedeck..if you play this on your bad cassettedeck the programm will show you if the tone is too high or low..
I am about to replace the belts on a Sony tc-wr875 double cassette deck and want to know if the flat belts (capstan belts) are they installed on the pulleys(idlers) the same as this model? Anyone know? Thank you
I replaced the two belts with a set from a “kit” online. The small take-up belt seemed too small and tight, but I installed them anyway. It SEEMED to operate fine, until it ate two two tapes! 😡. I wonder if anyone else has had issues with any of these “belt kits” you find online? And if anyone knows the actual Sony part numbers for the original belts?
Hi! I have this deck! I changed the belts but it doesn't work well. It works in play, but if press fw or bw it comes back into play with a lot of noise and it also ruined the tape.It is very strange because everything has been cleaned and nothing seems broken. Can i try something else?
Thanks for a very well produced video. I have the TC-K715S It hasn't had much use from new . Has been stored in a room and just powered on and off every year for last 15 years. When I pressed play last year nothing happened ie the captain doesn't engage. Could this be the belt ? Just tried it again and the eject does not function. There is no tape in. Any advise appreciated
So I have the TC-KE400S and I followed your directions exactly and everything worked great. Except for the fact that my tape plays at insanely high speeds. I went to the back and adjusted the two parts like you send but it didn't change anything. Is there anything else I could do?
Hello, I have a problem in replacing the pinch roller of my deck. I was able to take the pinch roler assembly and replace it with the new one. However there was a pin in the plastic assembly which holds the pinch roller that came off. I am not aware of how to place the pin in the assembly and put it back, Any help in this regard is highly appreciated.
Great video - managed to change the belts with not too many issues. Haven't used my tapedeck for years, finding the tapes are sounding somewhat underwater, just wondering if that's likely to be the fact that the tapes have been left in a loft for 10 years or not!
Cleaning the tape heads with isopropyl alcohol should help - I had the same issue. My tapes were in the loft too, so perhaps they need to acclimatise to room temperature. If that doesn't work, a demagnetizer may be required.
@@grahamnunn912 hmm unfortunately it seems that isopropyl alcohol is in some demand at the moment with the current situation! They're definitely acclimatised temperature wise as have been in the same room for the last couple of years. I have tried cleaning the head with some WD40 contact cleaner (previously used for cleaning a circuit board) but doesn't appear to have helped. demagnetisers do not appear to be cheap...
I have KE600S that needs some repair too. Does it have the same tape drive mechanism as yours? How many belts are there in that mech? Thank everyone for advance and advices.
I can only measure the belts that came out. The larger one is 104mm when flattened, but had stretched a bit so perhaps it's meant to be 100mm. The smaller one is 38mm.
7:20 On this mechanism, that little gear on the metal motor shaft is prone to cracking and spinning on the shaft, which causes all kinds of weird issues. If replacing the belts doesn't fix your tape deck, that is the likely culprit.
I can only measure the belts that came out. The larger one is 104mm when flattened, but had stretched a bit so perhaps it's meant to be 100mm. The smaller one is 38mm.
Great video and very well explained! I also have a question about my tape deck from Sony, so I changed the belts and it works too. The problem is when I press the stop button, the tape continues to run on the left side. What could be the reason?
I have a TC-KE500S that needs new belts. Would the TC-KE400S belts be the same size. Also do you know where I could order belts. I found a guy on ebay but they are in portugal. Do you know of any in the states or even give me the supplier in Germany. Thank you
The belts I ordered listed the other models that they were compatible with, and the TC-KE500S wasn't mentioned. So although I'd be surprised if they didn't share a mechanism, I can't say for sure that they do. Finding belts in the US might be tricky. The seller I used was 'phonohifishop' on eBay.
Hi Graham. Thanks for the vid. I have similar deck. Both belts have melted with age. No motors are running. Do the motors need belts for them to operate? Do I have another problem to solve now? Thanks.
I'd be surprised if there was a problem with the motors. Changing the belts is the first and least expensive step and should solve the problem - if you have another issue with the deck you won't be able to diagnose it until the belts are changed anyway. Just make sure to clean off all traces of the melted goop first.
If only I had seen this when I brought a dirt cheap one that had jammed the eject mechanism lol. Figured it out and replaced belts and rubber wheel though so all was good! One thing I have now discovered the flat cable attaching the drive using to the mainboard, mine seems to have an issue. Sometimes when no tape is in, it will say it has a type 4 tape in it. If I press a little on the lid near the transport unit, the indicator goes off. Sometimes recording and playing back the tape will just stop (I assume because it thinks it has no tape in it). I traced it to that cable. Now I am not sure if it is the cable itself or the socket on the transport circuit board. Does anyone know if either are available to buy?
It could be the reed switches that detect the type of tape you are usen they sit at the top of the door, they could be dirty or loose or misaligned. Hope this helps.
You can really tell how well put together a sony tapedeck is when tearing it apart. Im damn sure that on a cheaper deck those tabs to hold the belts while you put it back together dont exist at all.
Hello. Thank you for your video Graham! Sending you a message from Edmonton, Canada. I have a similar unit. A TC-K707ES. I would like to replace the belts. Where did you purchase yours from in a Germany? Thank you kindly!
Thanks for the video! I have a tc-ke500s with a problem. all mechanisms "work" but after a few seconds the music gets distorted and sound weird. I have cleaned and demagnetized the heads. Next thing is changing the belts. Hope this is the problem.... any suggestions?
@@grahamnunn912I changed them already, huge success :) All tapes I tried except for one played just fine. One tape still starts to distort after a few seconds which is weird, it plays fine on my other deck.
Do you mean that the eject button won't press in? From memory, I think that you have to spin the flywheel to reset the mechanism so that eject works again. I can't remember exactly as it's a year since I made this video, but I recall having the same problem. If the belt is broken or loose the mechanism can be stuck 'mid-cycle' - ejecting isn't possible in this state to prevent you from ejecting a cassette during playback. I think that's right anyway. If you've got it opened up you should be able to manually wind on the mechanism until it clicks and ejecting becomes possible again.
@@grahamnunn912 Thanks. Would the mechanism's flywheel be on the bottom right or left? Where is it? I managed to rescue the tape that was stuck but yes the eject button wouldnt press in so I couldnt eject. So if I replace the belt it possibly might be able to eject again? There's only one belt right? To access the flywheel, how much would I have had to unscrew to be able to see it?
@@antonisatwork The flywheel is the large grey wheel at 6:26 in the video. You can turn it with your finger without taking the transport mechanism apart. If you turn it enough clockwise you should reset the eject button.
Hello Graham,Is it possible to change the pinch roller on this deck without taking off the transport system from the chassis of the deck. I have the same deck which is working fine now, but the pinch roller is shiny and will wear out shortly.Thanks for any suggestion.
I didn’t need to touch mine, but I would doubt that it can be changed without removing the transport mechanism. Would rubber roller restorer solve the problem?
isopropylic alcohol over the whole parts and the belts. Maybe you should consider to buy another set of belts if you screwed them up too much. I f*cked up worst: inadvertly I pour WD-40 on the belts and the small white mechanism. Fortunately rubber alcohol did the best. Isopropylic alcohol is far better.
I didn`t change the speed but a little tip I`ve read many years ago: piano. playing piano it will tell you right away the right playing speed... and for the video part (contrast, colours, brightness ) are the waves.
you are really great for doing this. It's the exact same model as mine which made it really useful for me. I used the first half of your vid to diagnose. And sure enough same problem. The big belt had expanded and come off. Just ordered the belts fro Thakker. And I'll add in my result if you're interested. Do you recommend doing any additional maintenance while it's open?
@@grahamnunn912 I have little confidence when it comes to opening up an electronic component and fixing it. But....I DID IT!!!! Completely down to your video. You've unlocked a treasure trove of old music recordings I made decades ago. It means a lot. Thank you!
Thank you Graham, your instructions are first class, what was once a useless cassette deck is now playing brilliantly.
This is a masterclass in how to service a machine with crystal clear instructions. Hats off to you, Sir!
Thank you, I appreciate that.
A masterclass in how to service a machine with clear instructions. Thank you
…..Excellent, especially the speed adjustment, I was at a loss, as the normal back of motor adjustment didn’t work, thank you tons….. for this I use a cassette tape with a keyboard tone recorded in G played back to an old fashioned guitar tuner with a moving needle, works a treat…..of course this cassette test tape was recorded on a known correct speed recorder…..thanks again.

It is also worth checking that pinion gear you can see at 7:27 as they can split causing interesting malfunctions and chewed up tapes :(
You couldn't just by a "Chipmonks" tape to see if it was playing at the right speed?
What is the length of the 2 belts.

R72 is used for high-speed recording calibration only.
Thank you for this video,it,s helps alot.
Great how-to. Worked for me, thanks.
7:20 On this mechanism, that little gear on the metal motor shaft is prone to cracking and spinning on the shaft, which causes all kinds of weird issues. If replacing the belts doesn't fix your tape deck, that is the likely culprit.
Please , can you tell me the size of the belts of this device?

Great video and very well explained! I also have a question about my tape deck from Sony, so I changed the belts and it works too. The problem is when I press the stop button, the tape continues to run on the left side. What could be the reason?
I have the exact same issue. Did you find a fix?
@@LGKvideos No, the only idea I have is that the left motor may continue to run. Maybe solder the contacts?
out of all I watched this is on the money.
I have a TC-KE500S that needs new belts. Would the TC-KE400S belts be the same size. Also do you know where I could order belts. I found a guy on ebay but they are in portugal. Do you know of any in the states or even give me the supplier in Germany. Thank you
The belts I ordered listed the other models that they were compatible with, and the TC-KE500S wasn't mentioned. So although I'd be surprised if they didn't share a mechanism, I can't say for sure that they do. Finding belts in the US might be tricky. The seller I used was 'phonohifishop' on eBay.
Hi Graham. Thanks for the vid. I have similar deck. Both belts have melted with age. No motors are running. Do the motors need belts for them to operate? Do I have another problem to solve now? Thanks.
I'd be surprised if there was a problem with the motors. Changing the belts is the first and least expensive step and should solve the problem - if you have another issue with the deck you won't be able to diagnose it until the belts are changed anyway. Just make sure to clean off all traces of the melted goop first.
Thank you! The TC-KE500S is very similar.
If only I had seen this when I brought a dirt cheap one that had jammed the eject mechanism lol. Figured it out and replaced belts and rubber wheel though so all was good! One thing I have now discovered the flat cable attaching the drive using to the mainboard, mine seems to have an issue. Sometimes when no tape is in, it will say it has a type 4 tape in it. If I press a little on the lid near the transport unit, the indicator goes off. Sometimes recording and playing back the tape will just stop (I assume because it thinks it has no tape in it). I traced it to that cable. Now I am not sure if it is the cable itself or the socket on the transport circuit board.
Does anyone know if either are available to buy?
It could be the reed switches that detect the type of tape you are usen they sit at the top of the door, they could be dirty or loose or misaligned.
Hope this helps.
@@SDsailor7 you right, this sensors need to be disassembled and cleaned with a small sand paper.
You can really tell how well put together a sony tapedeck is when tearing it apart. Im damn sure that on a cheaper deck those tabs to hold the belts while you put it back together dont exist at all.
Hello. Thank you for your video Graham! Sending you a message from Edmonton, Canada. I have a similar unit. A TC-K707ES. I would like to replace the belts. Where did you purchase yours from in a Germany? Thank you kindly!
I got the belts from an eBay seller called Phonohifishop. They appear to still be trading. Thanks!
Thanks for the video!
I have a tc-ke500s with a problem. all mechanisms "work" but after a few seconds the music gets distorted and sound weird. I have cleaned and demagnetized the heads. Next thing is changing the belts. Hope this is the problem....
any suggestions?
Michael Ritzmaier Yes, it sounds as if the belts aren’t gripping properly. Definitely worth a try.
@@grahamnunn912I changed them already, huge success :) All tapes I tried except for one played just fine. One tape still starts to distort after a few seconds which is weird, it plays fine on my other deck.
Update: it was the pinch roller, changed the pinch roller and it's good as new :)
Very helpfull! Thank you very very much!!
Hi
How did you remove the tape that was stuck in the first place? I've opened mine up but I just want to retrieve the cassette that is stuck first.
Do you mean that the eject button won't press in? From memory, I think that you have to spin the flywheel to reset the mechanism so that eject works again. I can't remember exactly as it's a year since I made this video, but I recall having the same problem. If the belt is broken or loose the mechanism can be stuck 'mid-cycle' - ejecting isn't possible in this state to prevent you from ejecting a cassette during playback. I think that's right anyway. If you've got it opened up you should be able to manually wind on the mechanism until it clicks and ejecting becomes possible again.
@@grahamnunn912 Thanks. Would the mechanism's flywheel be on the bottom right or left? Where is it? I managed to rescue the tape that was stuck but yes the eject button wouldnt press in so I couldnt eject. So if I replace the belt it possibly might be able to eject again? There's only one belt right? To access the flywheel, how much would I have had to unscrew to be able to see it?
@@antonisatwork The flywheel is the large grey wheel at 6:26 in the video. You can turn it with your finger without taking the transport mechanism apart. If you turn it enough clockwise you should reset the eject button.
Hello Graham,Is it possible to change the pinch roller on this deck without taking off the transport system from the chassis of the deck. I have the same deck which is working fine now, but the pinch roller is shiny and will wear out shortly.Thanks for any suggestion.
I didn’t need to touch mine, but I would doubt that it can be changed without removing the transport mechanism. Would rubber roller restorer solve the problem?
Damn, I was careless and got some oil on the drive wheel and therefore on the new rubber. Does anyone have an idea how to clean it the best?
isopropylic alcohol over the whole parts and the belts. Maybe you should consider to buy another set of belts if you screwed them up too much. I f*cked up worst: inadvertly I pour WD-40 on the belts and the small white mechanism. Fortunately rubber alcohol did the best. Isopropylic alcohol is far better.
Thanks, legend. This was a great help
I didn`t change the speed but a little tip I`ve read many years ago: piano. playing piano it will tell you right away the right playing speed... and for the video part (contrast, colours, brightness ) are the waves.
Very helpful, thanks!
Thank You very much!! It helped me.
you are really great for doing this. It's the exact same model as mine which made it really useful for me. I used the first half of your vid to diagnose. And sure enough same problem. The big belt had expanded and come off. Just ordered the belts fro Thakker. And I'll add in my result if you're interested. Do you recommend doing any additional maintenance while it's open?
No need for additional maintenance as far as I know, assuming that everything is clean. Good luck with the replacement!
@@grahamnunn912 I have little confidence when it comes to opening up an electronic component and fixing it. But....I DID IT!!!! Completely down to your video. You've unlocked a treasure trove of old music recordings I made decades ago. It means a lot. Thank you!
@@ThunderbrainTV Excellent! Thanks for letting me know.
It helped me also...Thank you man!!! (Y)
Thanks for this video. Where did you order the belts?
I ordered them from a seller called 'Phonohifishop' on eBay - www.ebay.co.uk/str/phonohifishop
@@grahamnunn912 Thanks for the answer. I have now ordered it👍👍
Excellent!!! Thank you
So would you say that this tape deck is reliable? Does it have good playback and recordings? I just bought one, supposedly working, a few days ago.
Yes, I've always found it to be reliable - apart from the problems with the belts. The Dolby B, C and S noise reduction is very effective.
