tuner post bolts

Post  ack on Fri Oct 29, 2010 11:06 am

Hey all.
My '81 T40 was missing one of the tuner bolts (that hold the gears in place):

I've looked around for replacements, but I was only able to find "close" (the thread size is correct, the heads are different). I got 4, so they're all uniform, but I'm trying to locate originals.

Anyone point me in the right direction? I checked with Peavey - no dice.

Thanks,
Ack

Good Luck! That's the most sought-after T-40 part. The keys were Grover, if I remember right. I'd write them and ask if they're available. If you can, measure the threads as there are two of those type keys that have different threads.To be safe, and if you don't have thread gauges, scrape a light bit of pencil lead on one side of the threads and lift the carbon off with a piece of Scotch tape to send them.

Oh...Grover. I thought they were Schaller tuners.
I'll check with Grover and see what I come up with.

Thanks,

You may be right. Both companies make similar tuners and that may be the reason I find two thread types. You may have to try both.
Good luck,
Chip

Let us know what you find out, and what year is the bass? (It's difficult to see the 'natural' serial no. in the photo).

It's an '81.

I found an older post (on TalkBass) where a guy was selling a set of T-40 Tuners still in the Peavey shrink wrap (I guess they call that N.O.S.). I couldn't tell from the pictures who mfg'd them (Grover or Schaller), but the screw looked correct.

I found the original (missing) bolt - it was wedged between the foam and the material in the HSC!!
I'm so happy about this....how little it takes to keep me happy is amazing.

FYI they are Schaller M4SL
I emailed Schaller and Dr. Lars Buenning (Managing Director - Owner) verified the model.

I purchased one complete Peavey T-40 tuner (vintage, to replace a bad shaft) and found another interesting tidbit: my tuner gears have "large" holes for "large" shaft ends. The 'extra' I bought has a smaller hole in the gear and smaller shaft end. The screws mentioned here fit both.

here are the gears, for comparison:



This is the modern Schaller tuner from their catalog:

Update:

Schaller sent me the screws/bolts for the back of the tuner peg/post... too small!
Apparently there are two sizes that correlate to the size of the hole in the turning gear (above). Who knew!
I sent Dr. Buenning (Schaller's owner) the image and he replied the same day saying he is researching to send new screws. Too cool.

On the left: new "small" screw from Schaller. On the right: old "large" screw from Peavey T-40 Schaller tuner... hacked up by prior owner Sad
