Maybe if you call parts they can let you know what to order.

Generically, you can take a look at:

Call Customer Support, don't do any more guessing.

Thank you. I'll let you know how things turn-out

First option was to call Yamaha. Some items (non-"hard" parts) are below the cut-line and sometimes you run into a dead-end so I offered generic info as a backup. Not as a guessing game. Clarification is good to tack on as the original direction I gave was not explicitly clear.

Thanks for the link Jason. Very interesting reading posted by Kevin Lightner:

Even though its a good idea to check-in with Yamaha first, probably what I'll find is standard industry product/proceedure.
Will let you know how it goes.

Yamaha states, they don't know what type of fader lube. So, they connected me to their most knowledgeable repair/parts person.
She states that there is no-way she or anyone at Yamaha could answer that because it is a secret!!!!!!!!!!! , but that it must be a very thin type, which is completely wrong.
When I asked her to examine the fader personally, she returned my phone call and admitted that it indeed is not a thin lube, but remained steadfast about company secret and recommends to dissemble keyboard and replace fader even-though she had previously suggested to use a thin lube.
I am disappointed with Yamaha's response. Anyone here have some experience with faders? I know for sure that there is nothing proprietary about the fader and it's lube packing.
So my question is: Since there only a handful of basic-type lubes/packing for this type fader what would be your suggestion?
I believe that the information should be forthcoming and probably could be had through different channels.

If it is available through different channels, I don't know where those channels are. I don't know how you know for sure, if you did then you'd already have your answer, no?

Yamaha may themselves purchase the parts pre-lubricated which, if this is the case, presents an understandable issue in answering the question. Sure - there may be some intellectual property if Yamaha does apply the lubrication (or specifies to the factory what to use). But they may just order the parts as an assembly without touching them. So there may not be any conspiracy here. Who knows.

This is where the "cut line" warning comes up. I would personally seek out the best expert opinion on a recognized industry/repair tech/etc standard for an acceptable lubricant to apply and place my order once becoming satisfied I've seen a few sources agree with each other.

The safe/"expensive" bet is to have the instrument serviced by an authorized service center. It's always your call though.

Hi BM, To answer your question,... "then you'd already have your answer, no?"
No, I do not already have the answer but, I absolutely know for sure that any "EXPERIENCED" tech, especially at Yamaha would simply say, use this. period.
I will find the answer regardless from where it comes. The suggestion that Yamaha may be purchasing the faders "packed" is of course, likely, but has no bearing on the fact that a fairly large number of folks across the industry would be able to say with confidence, what products work for these faders. Believe me BM, this is true.
Jason... "Cut-line" warning,"Intellectual property"? Not so. I'll provide the info shortly. It should be useful.
As for Yamaha's response. Its just over the top typical of many of todays communication protocols.

The "cut line" / IP business was just alluding to my original message which was simply that you may not be able to find your answer by barking up the Yamaha tree. For whatever reason. I just had a feeling you'd end up where you did. Which is why I started to prepare for going another route.

Right Jason, I see more clearly what you meant, thanks.
CAIG Laboratories, which many here may know about, is one of the most respected manufacturers of chemicals regarding this subject. They have the right product concerning faders and specifically which one, I'll have that info shortly and let you know how effective it turns-out. There is a high probability that the fader's electrical performance will be slightly improved and most likely sustained beyond the fader manufacturer's expected usefulness under normal operation.
Their products should be in the possession of just about anyone concerned with audio period.
