Hi Brian,
thanks a lot for your info, I had a feeling it's important to use a proper grease. That P500 model is really good even after so many years, in 1993 it was top model, rather expensive. I like it and use it as my main MIDI controller in studio and as a source of interesting piano sounds, so I don't want to damage it. I will try to get original Yamaha grease.
Happy New Year!

Hi DanielIt is very important to use the correct grade of grease on these keys. It is readily available from Yamaha. ; Use of the wrong grease can have dire consequences.Given that Yamaha is a Japanese company and that you are in Japan I would suggest you contact Yamaha direct.There are a whole series of Clavinova’ that are suffering from the wrong grease where after a time the back part of the key, the fulcrum, cracks and the key then tilts over and rubs on the key next to it. This was a manufacturing fault, caused by the grease used attacking the plastic, resulting in Yamaha replacing key frame assemblies FOC.As far as I’m aware your P55 is not one of them.RegardsBrian G3OYUFrom: vintagesynthrepair@yahoogroups.com [mailto:vintagesynthrepair@yahoogroups.com] On Behalf Of Daniel Forró

Subject: [vintagesynthrepair] Re: lubrication grease in Yamaha keyboardI just started cleaning of my Yamaha Clavinova P500 after 18 years.
It needs complete disassembling of weighted keys. I just have
mentioned white creamy lubrication grease used on some friction spots
and joints. Because I want to clean the keys well, this has to go
away and I have to put there something similar.
I wanted to ask here if by chance somebody knows what is it, or which
substitution would be good and work without problems. I use the
instrument only in my studio, and here in middle Japan we have hot ;
(up to 42 C) and humid summers. So i suppose grease should work well
under such conditions and not flow away.
Thanks for advice in advance, and Happy New Year to all here!
