    Hi guys,

    Recently bought a second hand MIM 70s jazz bass, got it at a really good price but noticed one of the machine head bushes was missing. I've managed to get hold of a new one, but the bush won't go in the hole.

    What's the best way around this?

    Thanks

    I would strip the bass, and fill the control cavity with whatever soil would best support your local flora and/or fauna. Plant at the beginning of spring.

    Good luck!

    :D dang Americans making fun of UK lingo again!

    Now, you'll need to get a bushing that fits. Maybe the one you have is metric and the mim is inches? Or vice versa? Pull an existing one and measure.

    However, once you determine that you have the right ones, you MUST PRESS them in using a clamp. Never bang them in with a hammer.

    Just don't shave it for a while :D

    What 96tbird said. They don't just fall into place, they have to be pressed in. If it feels like it will almost go in but not quite it is probably the correct size.

    Haha had me thinking for a second then, I take it they're not called "bushes" in the US.

    Thanks for the advice guys, sounds as if the one that I've got is too big, as it doesn't even slot in at all.

    I'll buy genuine fender ones to be on safe side.

    Thanks

    I think Fender offers the direct replacement. Should drop right in. Good luck!

    The same trick is used to install U-joints in a drive shaft. But a vice is used instead of a clamp.

    Personally I just tap them out with a dowel rod and the palm of my hand. They are never that difficult to remove, and that is a way over complicated solution to a simple problem. I press them back in with a bar clamp with rubber pads.

    No, I made up the method all by myself.

    I've liked the term "gudgeon pin" ever since discovering it in a British racing engine manual. In the U.S. the term is "wrist pin." Gudgeon seems like a name from British satirical writing, ("Mr. Gudgeon could wither a flower garden with the merest twitch of an eyebrow.") Or something like that.

    Yeppers, when I started working on Triumph engines all I could get was an official manual from England and it was written in the king's English so it took me a minute to translate it.

    As for the machine head bushes, I've always pushed them out with finger pressure, and put them back the same way.
