Finally; a video where I can actually see you put the two parts of the mechanism together and I can see HOW you put the belts onto the rollers!! You’re my hero. Thanks a million!!

Well good job for an amateur. It's a professional work you did. Even a professional technician started by making mistakes then he learned from it. I really appreciate your work ❤️

Thank you! This is the clearest and best-photographed tutorial of its kind that I’ve seen so far

Thanks! Your video helped me replace belts in my Sony MHC-3600.... without watching video I don't think I would be able to do it on my own.... old belts basically disintegrated lol over years from heat or just being old, and there was no way to see it belt routing before taking apart. Big thanks!

Boy! I feel so lucky! I just bought the identical deck, in perfect shape, from our county's electronic recycler for five bucks, but the belts are a melted, gooey mess! You just saved me a bunch of grief! LOL! Fantastic video! Thanks!

I wish all explanatory videos were this clearly shown and well-explained. This isn't even my model of cassette deck but I still couldn't stop watching all the way through to see what tips I could pick up. Thanks!

I followed the excellent tutorial and got the goop out and the belts in. The good news is that everything runs. The bad news is that there is regular clicking on both decks, in both directions. It is obviously tied to the counter because the clicking is faster when the hub on either deck is spinning faster. There is also a background hum. I've checked all the connections and wiggled things while it was running. So, unfortunately, I have several hours down the drain and a deck that will be going to the dump next week. Absolutely GREAT tutorial ... this has nothing to do with your efforts. It simply shows that sometimes there is more than one problem.

Watching the video really touched my heart. There was endless love for every product in Japan.

Thank you so much for such a well-done video! Works like a charm!

This is great. Just Sunday I was given my mom’s old tape deck, which is a Sony very similar to this one and lo and behold, the belts need replaced. Once I get the belts I’ll be coming back to this video. Thanks!

Thank you!!! Fixed my 25 year old Sony TC-WE625 and it works like a charm again.

Big thanks for this, a real public service. I really liked that you did this slowly and showed clear images of the belts on and how to just pop them onto the riollers once assembled which others don't spend enough time on. It worked for my sony double cassette tc w490. So happy now going to repair those other decks lying around, keep the best and sell the rest off.

Thank-you very much for this video! I have the same model, made later in November of the same year, so this was spot-on. My old belts were just sludge. I found that alternating between an alcohol soaked Q-tip and a GUM floss pick really helped to clear those tiny pulleys with their tiny crevice.

You sir are a diamond for going to the trouble of putting this video up. Great help.

Thanks for your video, with this I changed the belts of a Sony system with the same mechanism, that was used by my father in the 90s. Thanks!!!

Helped me a lot to fix my TC-WE 835S. Had an issue at first, redid the whole belt thing, this time I paid more attention to a nice looking alignment of the white plastic wheels thingy next to the shorter belt. Reassembled, everything's fine now.

That is a most helpful video indeed. I will try this new knowledge on my TC-WE525 which looks a little different on the inside but it's from around the same time beginning of the 90s so I'm not expecting too many surprises. And you are very brave using your very first tape for the test run on your re-assembled deck. The deck could have done all kinds of bad things to your tape but you just believed in the quality of your work. 👍

Someone just gave me a NIB WR565 and the belts have turned to goo. I've re-belted a lot of turntables, VCR, tape decks, etc., but it is amazingly useful to benefit from your mistakes (which I most certainly would have made) and to see how to use the posts to hold the belts while you put the "clamshell" back together. Thanks!!😀

Excellent! Simple, slow step by step instructions and great clear closeups so that one can actually see what's going on. And thanks for not putting any distracting background music throughout like some people do, lol. Good job! I have a Sony TC-WR520 that needs new belts. I've taken it apart to look around in it and just need to get some belts. I'm going to see if mine can disassemble like yours. I too had taken the whole unit out. I'll try it like yours. Also, I didn't know thats what those posts were for on the belts. I assume you found an online repair manual because I never would have figured out how to put the belts on using those posts. I did find a manual with diagrams for mine but it doesn't anything about wrapping around those posts (The manual calls them "claws") and then pushing them off and on the rollers. I wasn't sure what they were for.

Many thanks. I repaired similar Sony dual tape deck from scrap.

Thank you! I look forward to bringing my TC-WE471 back to life with your help!

Thank you for this video. I have the TC-WR775. It's a bit different but the belt concept was similar and helped me out big time.

I saved this to my favorites for when my belt kit shows up 👍

That was an excellent video I've seen other people do this and they didn't show it very good. I have a Sony TC- Wa8es that needs belts this shows the general concept . Thank you

Fantastic video. I'm going to attempt to do my TC-WR775 thanks to this info.

Excellent video I use your video to fix mine! it was a piece of cake with your video as a reference!

Muchisimas gracias! Este es el tutorial es excelente es mucho más claro y mejor fotografiado de todos los que he encontrado hasta ahora ... gente tan profesional como tu ,explicando y proyectando la imagen tan de cenca . Es una maravilla y un placer, el poder hacer uno mismo estos trabajos sin tener que gastar tanto dinero en el taller para reparar la Platina de Casete. Mi unidad es un Sony tc we705s y me ha sido de gran ayuda el hacerle el cambio de correas gracias

Excellent video!

WOW thanks for this. I have a Sony that sounds like the belt is slipping so I'm going to order the correct belts and see about replacing them before tossing the unit.

Good job man!! Nice video and the picture quality is great

Great video. It really shows how to resplacing sony cassette TC-WR690 isn't that easy. I use alot of Q tip and 70% rubbing alcohol cleaning off the old belt.

Great video, you don't appear to be an amateur, great tutorial 👍 now I know I can make this myself I have a Sony tc w250 that needs belts replacement. Thanks for this video.

Super helpful video! I just got a TC-WR635S which appears to have the same deck mechanism.

Great video! You work better than many technicians do ... You got mi LIKE! Regards!

I also have a sony fh b170 music set. The cassette part of this one is the same as the 690. I think its belt fits too. Because everything is the same.I was very informed, I did the same. Thank you very much

Thanks a lot i used this video for an older model but it worked perfectly

Thank You, Very Good technical Tutorial. Warm regards From Portugal.

Thanks so much. Excited to get started on mine.

That was the deck I had! Great deck! If you ever decide to let it go, I'd be interested for nostalgia as I am currently using an inferior TC-WE305

GRETA video, thanks. I have a TC WA7 ESA cassette machine and I am HOPING it repairs up the same way.

Great! Thanks für this Video. Will start fixing my Sony deck right now!

I now feel very confident I can fix my hardly ever used Sony dual Stereo cassette deck. I believe I purchased mine in the early 90 also, I have taken it apart to see what was going on and I could see the belt had broken more than likely from just being old and not being used, and knowing that the ribbons just come out of the deceptive clips LOL I didn't want to force them because they didn't have anything that looked like a release pin. Thankfully I decided to look at KZfaq and found your video very clear and well recorded Great job! now I will search for belts.

A lifesaver ,thank you

Suggest to adjust tape speed (and high speed dubbing) since the new belts add more tension to the mechanisms.

Exzellent Video, thank you! One question: when installing the small belt, in which direction shows the end of the spring? I am not sure about that...

Super helpful. Thank you!

Nice worrk sir

great video. is there any chance to find out the length of both belts? any dimensions?

Thank you!!!!

Some Sony cassette decks are over engineered and it can be a hassle just to replace the belts. Not including if you have to replace a gear or a cog. Idler gear are the worst to work on. Especially if you can't find parts.

4:40 gracias

THANK FOR VİDEO

Thank you 👍

Hi Tech Stuff, nice video, I have an SONY TC-EX90, but the mechanism is the same as yours, but whet i change the belts, what I put it back together and tur it on it starts to make a grinding noise, and them starts fast forward and i cant do nothing. Any help please? Thanks

Bravooooooooooo

Do you have any idea where I could find the gears that are around the smaller belt?

I just followed this tutorial. One deck has the playhead and pinch rolls engaged that i cant seem to get to release The other plays in the wrong direction and unspools the the tape. Any suggestions?

Lbt d305 sony have this same mechanism

SOS! Cleaned up all of the goo and added new belts. Now my right side tape deck won’t accept Tapes like they are too big. I can’t figure out how anything is misaligned

Where can I find belts?

I changed the belts put in a new tape and all works, but if I press stop the tape spins back a bit. Then press play and it stops as the tape is lose. If I press rewind and play all fine. Stop and play dose not work, Same on Bothe sides? Any ideas how to fix this. Thanks!

thank you but i live in turkey. original belts is no here. please write me belts dimensions (sory about my bad english)

Hey! What are the sizes of pinch rollers?

Can someone tell me the sizes of the belts pleassee

When does a tape deck need a belt replacement ?. I recentely got a tape deck/ cd stereo from one of my friends very good condition but he told me he never really used the tape deck only cd player, so do you think it might need just some demagnitizing if the tape audio sounds slowed down?. I recently tried it and the tape deck sounds slowed down. Plz help

So I followed the instructions and it turns on, and the motor screams, Ive lubricated the motor, and connected everything as I see it in the video, but it still just eats my tapes. Any suggestions?

my tc-w411 is missing the smaller wheel that touches the large belt at 7:16, is thie normal?

I've got the sony tc-835s is it similar to replace the belts

well surely the late decks were more economic but I think this is a cheap model itself as most of all double cassetes with no bias and rec level adjustments and no oscillator

every piece of rubber is liquid goo, I don't think I can save this one.

HELLO BELT SİZE ?? NUMBER
