Replacing Keyboard Felt on a Yamaha Clavinova CLP-820

[@RA-el6zj]

Finally someone showing clearly how to properly disconnect the keyboard. Thank you. 👌🏻

[@ragzpar]

I have the CLP-970A. The initial steps were a bit different but the meat of it was all the same. Thank you so much. It cost me only 37$ instead many hundreds of dollars if i had to have someone fix it for me. On hindsight, think just the bottom felt should be enough to fix the sound problem. The top felt didn’t get any damage, it was all the bottom felt that took all the beating. Next time, i’d recommend to order just the bottom to get it fixed for just 15$. Thank you so much for your video.

Man, I have been waiting for this video for 15 years!!!!! Thank you so much!!! Once I had to pay USD 200 to a rogue technician that replaced the felts and the job just lasted for couple of years... Now I will do it myself and properly!

[@georgesmith7252]

Thanks for the very helpful video. Used it to change felts on my CVP 96. A few more screws had to come out to get the keyboard out but otherwise just as you described. My piano sounds amazing! Thank you !!

[@louisegoulding3604]

Thank you so much for this video! The process with a CLP-840 is abit more complicated as i had to remove the keyboard cover and there were quite a lot more screws, but the general process was the same and I successfully replaced both felts in a little over 2 hours. So pleased with the result, no more clunking and the piano actually sounds sweeter. Thank you again - you are a star!

[@gprakasham]

@louisegoulding3604 : I do have CLP-840, Can you pls share where did you bought the felt and the part number?

[@jamesmoats4103]

I had to replace the upper felt on my Yamaha CP4 and thanks to this video, I got it done. Thanks a lot.

[@laceyc.6104]

Thank you! I was able to replace the felt and my 20 year old CLP-840 is like new!

[@Ipergenio]

Great tutorial! This morning I've replaced the bottom stopper on an old CVP 103. Clavinova pianos seem to be all very similar to open. Just some little difference. Thanks for the useful guide!

[@alf3752]

Thanks for this vidéo, I followed it to change my both felts on CLP-820, perfect result!

[@toysun888]

Feel happy for you! Can you tell me where you bought the stopper felts? Thanks!

[@amarjitbassan7310]

Just bought a second hand 820. £200. Keys sound clunky. Think the felt needs replacing. Where did you buy the felt from?

[@llj746]

Thank you so much for uploading this video. It is very helpful!!!❤

[@musicroom7185]

Thank you for this video. Sounds like new again!

[@resynthesizer4565]

Nice video, thanks. Syntaur has the upper and lower felt. I am not affiliated with them. I buy spares from them all the time.

[@AFiB1999]

Thanks Roy, Ill be replacing soon. Very well explained

[@billkahler]

Yamaha has parts that work on many pianos interchangeably. Some of the keyboards are obsolete. Check Yamaha 24x7. You might need a service manual (not owners manual) to get the part number or you might have to call Yamaha. Also some parts are available on eBay, sometimes at higher prices than Yamaha, sometimes less. A note about taking off the felt - mine was really a sticky mess. I tried a heat gun. Worked on the adhesive but melted the plastic a little. WD40 works great. I used long needle nose pliers and lifted up a side of the felt rolling it slowly and squirting a little WD at a time. The spongy rubber soaked it up and I was able to get pretty long pieces off at a time. I cleaned the surface off with alcohol and a paper towel. This was on a P90, by the way. Lots of parts are interchangeable including felt. I used felt meant for a P120 on a P90. Exactly the same thing. I thought it was a little short at first but it stretches and lays flat if you install it from one side and go along little by little. Here is a compatible list for white keys: CLP-110 CLP-240 CLP-270 CLP-810 CLP-811 CLP-840 CLP-860 CLP-880 CLP-911 CLP-920 CLP-930 CLP-950 CLP-970 CP-33 CP-300 CVP-92 CLP-115 CLP-120 CLP-130 CLP-150 CLP-170 CLP-230 CVP-94 CVP-96 CVP-98 CVP-103 CVP-105 CVP-107 CVP-109 CVP-201 CVP-202 CVP-203 CVP-204 CVP-205 CVP-207 CVP-208 CVP-209 CVP-210 CVP-307 CVP-405 MO8 Motif 8 Motif ES8 Motif XF8 Motif XS8 P60 P80 P90 P120 P120S P140 P155 P200 P250 PF-500 PF-1000 S08 S70XS S90 S90ES S90XS YDP-113 YDP-121 YDP-223 YPT-121 Korg C6500

[@NicoSensei]

Thanks for that very helpful video! I just went through the same process on a 20 years old CLP-920, there's a top lid but it's very simple to remove it. Now we're good for another round 😁

[@Frankie-C68]

Great job young men!

[@ronaldeng3454]

What a helpful video and patient, well behaved, little boy!

[@billkahler]

To hold the key hammers out of the way you can run a dowel through. 3/8” or a little smaller.

[@leandrogutierrez158]

Many Thanks ...

[@jameslabs1]

Dissection. Cool.

[@nembuss]

Definitely the felts are the problem with my Yamaha P-105, but I can't find any store where to buy them.

[@RobStone84]

How did it sound with new pads with power turned off? Did thumping go away completely? Could not detect thumping while he was playing at the end. Sounded great! Awesome video! Doing this in a few days when pads show up. Thanks so much for this video!

[@FreshAirRules]

Its truly amazing how many KZbinrs forget to do the comparison exactly the same way they demonstrated the problem in the beginning!

[@steveroy1]

Yeah, sorry about that! I was just looking back at this video and thought the same thing. I can tell you that it was super quiet after I replaced it. Before the replacement, you would have heard the thumping as my son played - it was annoying and distracting.

[@RobStone84]

@@steveroy1 we ended up having to replace the whole keyboard module with a newer revision since keys started dying. Set us back $800 but was cheaper than new piano.

[@ecsyntric]

cannot tell if it made a difference due to the music

[@robertojparraf1]

Gracias

[@novakant3048]

Sad to say, I bought the upper and lower felts for a yamaha p-85 since the noise mine makes sounds just like the felts are worn out. After replacing them, it is no better than before. It has to be something else in my case. Very discouraging to buy these for $80CAN and have nothing to show for it.

[@FreshAirRules]

You probably need a lower density so they cushion the impact better. The P85 was always kind of loud that way. The P95 and up are better. The 105/115/125 are great. Maybe they just came with cheap felt and you can opt for a better quality one from a different model. Key return noise drives me nuts. Its one of the worst aspects of digital pianos. I've heard weatherstripping can work well. Not sure if you need open or closed cell foam or something else. But you have to choose it carefully. But it should be incredibly cheap. Probably 1/10th the cost of what you paid. One could also buy a tiny piece, then put it under the key to see how loud it is. Any window or door contractor is sure to have scraps they could give you. Keep in mind you want the key to have the same amount of travel it had before or very similar. So the cushioning should be close to the same thickness of the original I would think. And probably the same shape. Like you wouldn't want automotive weatherstripping which often is hollow and tubular. There is noise when the key goes down and noise when the key returns. So there's usually 2 cushioning areas on every piano. Some pianos like the Kawai use special grease for a lubricant and cushioning but I heard that Vaseline can also be used because getting that special grease can be difficult. And buying it from the manufacturer probably costs a small fortune.

[@Benson_Bear]

@@FreshAirRules Thanks for your comments, here are some replies: I tried weatherstripping also, with about the same travel distance for the keys and about the same compressibility and springiness. It was not any better. In fact worse, because something about the weatherstripping (surface texture I guess) made it that the keys that were not used for a while (like if you dont play for a day or so) stuck slightly to the surface of it and the first striking of the key had to be harder! This went away after first strike. My conclusion at this point is that most of the key return noise is due to something internal to the key, which is a bit of a mystery really. Also it seems very difficult to lubricate them; it is hard to see what point needs lubrication and how to get it in there. If one uses the wrong lubrication, I have heard, this could get markedly worse, and I believe that. Maybe I will just get a new piano but that is a big budget hit for me! I don't think the noise (even if due to lack of lubrication) actually affects the action much. If I play with headphones I don't notice it much.

Link for felt online buying please

[@toysun888]

Thanks so much for the video. I have opened up my clavinova cvp-103 and prepared to replace both syopper felts. However nowhere can I purchase brand new replacement parts in Hong Kong (where I am), nor over the internet. Can someone kindly tell me where and how I can purchase this pair of stopper felts? Thank you! Ricky Yung

[@Ironsmithwins]

Hello! It's applicable to Clavinova CVP705? Thanks in advance

[@kenw2046]

Thanks for the great sharing. What is the part number? Thanks!

[@willo7979]

I’m thinking of, instead of replacing the foam/felt strips, great if i can just carefully peel it of and still keep the whole piece intact, and just shift the strip sideway by half a note away, so hammer rest on foam/felt surface that’s still good?

[@Ipergenio]

this doesn't seem a bad idea

[@billkahler]

Bad idea. The felt comes apart because the adhesive is so strong and sticky. It won’t be reusable after removal.

[@willo7979]

@@billkahler there are many ways than double sided tape to bring two surfaces together.

[@billkahler]

@@willo7979 you surely can try it, but for me the entire strip of felt layers and sponge/rubber and adhesive disintegrated into little bits. Good luck.

[@willo7979]

@@billkahler definitely it takes some skills, for example; - you need to know that a dab of IPA releases the adhesive bonding of the thick felt from plastic frame, - you need to know that you’ll need a plastic blade to gently peel the adhesive off, not pulling it by force. - you need to know that the adhesive will stay intact and reusable when ipa has dried off If that’s too much of a skill for someone, then yes, get new felt, as there’s more than one way to solve problem.

Help, soon after turning On my Yamaha Clavinova Keyboard, there was a loud, short~lived noise, which essentially like killed the most enjoyable music machine , and need expert advice on what to do. Roger Nichols CHarleston, WV. 25304

[@michaelhatch1994]

I have a Yamaha electric piano CVP-7 that got a lot of use during covid and I cannot get Yamaha to respond to a service request for new felt. Looks like I'm headed down the "weather stripping" road. Shame really.

[@digitalbphotos]

Any chance you have a part number? I've got a CLP-840 (just about identical to yours) that I need to do this to. I called Yamaha Canada and they were completely useless. Sent me some pdfs for me to figure out which part I might need... but they're impossible to decipher.

[@FrederiksbergFestspil]

For the upper part, you'll need: WF212001 and for the lower part: V7640101

[@balacv02]

I followed this video till the 11 screws and side pieces were removed on my clavinova clp 735. But the keyboard won’t lift up the way it is shown here. Any ideas. I am stuck

[@Cheiz87]

I did it on the CLP-950. Apart from also having to remove the closing lid with 2 screws, for the keyboard I had to remove also about 10 screws that connect the keyboard to the bottom; you see them at around 2:50 in this video; I don't know why this is not shown in this video? After that, I also thought that the keyboard was still stuck, but with some gentle force I was able to push it back a bit and then lift up (not lift up like in this video). Next time (if there will be a next time) I will only replace the lower felt I think, the upper is the most work and doesn't make a lot of difference, the lower felt (key release) was a big improvement though!

Hi sir. I do have a unit Clavinova 930. I have few queries during my DIY repair. I'm not sure whether is circuit board (key notes) or the rubbers and felt. Pls advise.
