J Free Posted October 22, 2019 Share Posted October 22, 2019 I'm doing a refresh on my Kronos 88 keyboard-new felts, clean and lube. Does anyone know what the proper grease is for the action? I can't seem to find a definitive answer. Quote Link to comment Share on other sites More sharing options...
The Real MC Posted October 22, 2019 Share Posted October 22, 2019 Something that doesn't cause the felts to swell and ruin the action? No clue. Not something to trifle with lightly. Quote Link to comment Share on other sites More sharing options...

dongna Posted October 22, 2019 Share Posted October 22, 2019 I have to say I'm shocked to learn that keyboard actions rely on or require grease at all. I would not have thought the friction needed to overcome would be nearly great enough to require it. Quote Link to comment Share on other sites More sharing options...

I would not have thought the friction needed to overcome would be nearly great enough to require it. Some use it for lubricant. Standard on the polymer bushings for Pratt-Read keybeds (US keyboards) before the mid-1980s. Some use it for "resistance" to simulate a weighted piano action. Quite common for DPs.

J Free Posted October 22, 2019 Author Share Posted October 22, 2019 White lithium grease. everything I've read says not to use that-it dries out and causes other problems. Have you personally used it and had a different experience? Quote Link to comment Share on other sites More sharing options...
Song80s Posted October 22, 2019 Share Posted October 22, 2019 I don't believe Kronos is like a car, needing grease, etc. Why do you feel your Kronos needs this work ? Is it DIY stuff on your part ?

Anywhere that you have two surfaces rubbing together, a lubricant will help prolong the life of that joint. Grease and plastics can be tricky because you can have issues where certain grease types may weaken the plastic or cause dimensional changes (swelling). Have you tried contacting Korg to see if they'd divulge what lube they're using?

J Free Posted October 22, 2019 Author Share Posted October 22, 2019 I don't believe Kronos is like a car, needing grease, etc. Why do you feel your Kronos needs this work ? Is it DIY stuff on your part ? It started with a droopy black key (bent hammer), and some keybed noise (worn and damaged felts) After 8 years everything is pretty dirty. I figured while it's all apart I'd clean and regrease. Things are currently greased-moving parts with close tolerances require it I suppose. I did reach out to Korg, haven't yet heard. I do know some lubricants would not be appropriate because they don't play well with rubber/plastics. The silicone base probably is the right idea. I was hoping that someone here had first hand experience with something that worked well. cheers- ps MAJUSCULE-sorry about that Quote Link to comment Share on other sites More sharing options...

I would expect some wear on felts. Some key bed noise is normal. [ this has to be defined] it appears your K has heavy wear. Mine is 8 yrs old. I don't understand ' pretty dirty ' ? Huh ? Like lots of dust and pet hair ? Anyway, not all key beds are created equal. I think you should follow what Korg advises and/or what Korg auth service proposes.

That wasn't me on the Korg forum, although I did look around there. It's my gigging board-it gets bounced around on a truck-it does outdoor shows, etc. It's dusty, bits of fuzz, and actually dirty, like the sides of the keys are somewhat black, etc. Regarding the keybed it's worn in the middle, meaning it feels and sounds different in the center of the keyboard. Ledbetter-that might be a good call Jazz+-I was thinking of using something called "Slick Honey" that I use on my bike. The consistency is very much like what's on there.

ksoper Posted October 24, 2019 Share Posted October 24, 2019 Dow Corning #7 silicone lubricant is what was recommended to me to lube the Model D's Pratt-Read action. A little goes a long way.

EricBarker Posted October 24, 2019 Share Posted October 24, 2019 Silicone Lubricant... you can find it at any automotive shop. and "A little goes a long way" is an understatement. The applicators for these tend to push out the grease in bursts, so you gotta be very spare. I've done a lot of repair work on my Fatar beds, and grease is very good to use. I often wash my keys when removing them, to clean them of particulates that tend to build up in the bars I play at. But that removes the grease, so I need to re-apply it. Spring action beds don't require grease, so unweighted players are likely unfamiliar with the practice. But if you look up any tech sheet on keybed maintenance, they'll recommend it. Quote Puck Funk!

There's still 99.999 percent left in the tube. Maybe more.

EricBarker Posted October 25, 2019 Share Posted October 25, 2019 That's good to know. Mine came in a giant red complicated applicator from O'Riley's. It did the job, but it was kind of messy.
