Hi there. So my XF8 has been bleeding screws since I got it. It was already missing some, and I didn’t tighten the others when I bought it. D’oh. I’d like to go to my local hardware store and buy the right screws. Are there specs for exactly what screws I need? I can eyeball them and guess, but I’d like to make sure I have the optimal length, width, and thread pattern (the twirly screwy circlies that make a screw a screw). I’ve looked online from the yamaha site to sentaur to here and can’t find the info. Thanks! |

Here is a service manual. You can look up the part number and check with Yamaha what a replacement screw spec would be.

SM https://elektrotanya.com/yamaha_motif_xf6_xf7_xf8.pdf/download.html See pages 189 and 191 of the PDF. The description gives type of head, whether tapping thread, and diameter x length (in millimeters). Getting a precise match from a hardware store will be hit-or-miss. That’s particularly true for tapping screw threads (pitch), less so for machine screws. Bringing along some from the XF8 would likely improve the odds, but I suggest that you order the screws from Yamaha. |

Same thing happens to me....I am constantly finding screws on the floor from the bottom of my XF8. |

Adding toothed lock washers might help.
By the way, it isn’t a new problem…

Thanks for the input, all. I’ll try ordering from Yamaha. I’ll probably pay extra, but better safe than sorry. I don’t want the wrong screws coming loose in my road case and scratching up the beauty that is the XF8 WH. Cheers! |

I have never had an issue with screws falling out of my XF, or any of my other gear for that matter, but I sometimes find loose screws that appear to have come from my head.... |

I suspect many of us have had days like that. Â :-)
Which raises a question…
I’m, of course, referring to…

This thread is very interesting. How on earth is this happening? (ruling out paranormal activity, of course) |

Unlike the 61- and 76-key models, which have metal bottom covers, the 88-key ones have wood composite (fiberboard) bottom panels. Even if screws are properly tightened initially, that material tends to compress a bit over time and the screws will loosen. Presumably, vibration and gravity do the rest. |

I’ve played one a few times, but never looked under one. This thread was enough to make me check the screws on my XF7 though, before you pointed that out. |

That would certainly loosen things a bit further. But a few more screws loose would probably cease to be an issue at that point. |
