Sign in to disble this ad
Two of the tuners on my BB1500 have become "rattly". They still work, but whenever I play a loud, low, note they rattle, which is quite annoying (practically inaudible on recorded tracks, but annoying while playing). Are there any replacement tuners that will fit? (preferrably without any extra drilling....) The holes for the tuners are ~18mm in diameter and the tuning pegs ~13mm. The tuners are mounted with 3 screws.
This is the bass I'm talking about (only that mine is natural, not redburst):

Yamaha gears of yore had a tension-adjustable collar just below the "Y / Cloverleaf". The collar itself actually had two small holes on either side to acccommodate whatever tool was necessary for tightening or removal. I have the same thing on my '80 Hondo. From what I can make out, your's has the same set-up. Is it possible that these may have worked loose? Happened to mine.

In any case, the only tension adjusting screw is at the bottom of the tuner (as seen in the pic). This affects how hard it is to turn the tuner, but this does not in any way affect the head (Y/Cloverleaf) part which is what has become loose.

Its tough to tell from the pic but is the portion of the shaft directly below the Y threaded into the tuner body in any way, shape, or form? The only way to tell would be to hold the Y firmly and, with a well-cushioned pair of pliers, attempt to loosen that part of the shaft. Your description of a "loose cloverleaf" leads me to believe that may be the problem.

Riis | Nope, it isn't. You see, as I said it is just the cloverleaf that is loose not the shaft.

I'm digging as I'd hate to see you spend money on something that can be repaired inexpensively with Loctite (red) or adhesive.

Riis | It's not threaded, it's basically just stuck onto a rectangular peg.

I guess the task would be to secure the two together and, seeing as there are no other fasteners in the equation, I would consider using a super adhesive like marine epoxy or WeldBond. Of course, be careful not not to get any overflow on the surrounding parts. I'm leaning towards to the marine epoxy as the stuff, once fully cured, can be drilled, tapped, sanded, painted, etc. I've used it to repair garden tools.

I was ready to buy new tuning keys for my old '80s BB300 fretless because 2 of the 4 had loose clovers. They had a gap between the clover part and the post. All I had to do was grab the posts w/ needlenose pliers and turn them counterclockwise which closed up the gap nicely.

The "collar" on my BB400 does indeed have two small holes that a right-angled tool could fit and turn. I just used my vice grips - with some electrical tape on the "teeth" and tightened the collars as needed.
I like that I can set the tension on all the machines to a similar feel, just a little tighter than before.
Now, what's the best way to clean & polish up these?
