Introduction: Piano Clavinova - Change Key Stop
If your keyboard is too noisy (volume at minimum, key pressed and depressed make a loud noise), then you can change the stopper and stopper felt (~50€)

- first refer to the manual!
- 2 people is mandatory
- time required 2H45...
Step 1: Opening the Piano
follow the steps in the manual p12
12. Keyboard Assembly
12-1. Remove the top board assembly. (See Procedure 1)
12-2. Remove the key cover assembly. (See Procedure 5)
12-3. Remove the panel assembly. (See Procedure 6)
12-4. Remove either the rack assembly L or R. (See Procedure 8)
12-5. Remove the end block assembly L, R (See Procedure 9)
Step 2: Removing the Keyboard Part
12-6. Remove the nine (9) screws marked  and the two (2) screws marked . (Fig.9)
12-7. Move the keyboard assembly backward, hold the central area of it, and get it upright to remove. (Fig.10)
* Holding both side ends of the keyboard assembly may twist and damage the frame.
Step 3: Handling the Keyboard Part
Surprisingly, the keyboard part is not rigid: it's required to handle it with the keys vertical
I experimented an "Oh sh*t" moment when a key dropped...
Step 4: Removing the Old Foam
there is another the tricky part: it's really sticky
use an Xacto knife, a screwdriver and be patient
Step 5: Rebuilding the Piano
Remove the dust with a hoover
When reinstall the keyboard assembly, tighten the screws marked  and the screws marked  in the right order. see manuel p12
Step 6: Conclusion
- take time to read the manuel instructions
- I had some scarry moments
- don't do this alone ;-)
And frankly, my piano wasn't probably too noisy before, because I haven't got any sigificant improvement... Ha ha
