Peavey Truss Rod Adjustment

Hollywars · #1 03-13-2010, 05:54 PM

My Peavey TL-5 needs some truss rod adjustment. This is a fact.

I order the truss rod wrench from Peavey, and lo and behold, it is just impossible to get it to fit on the truss rod nut!

I check my dad (mkoby)'s Peavey Pallaedium (sp), and the truss rod nut on his is a good inch shorter, which makes it possible to put the wrench on.

In short, is there something wrong with the TL-5's truss rod nut? Am I doing something wrong? Should I try to shorten the wrench?

I'm not even sure if this is the right section, so move it if that's what should be done.

Nobody has any solutions or pictures of their preferably pre-1991, as in with Super Ferrite, TL-5's?

I'm not sure what you mean by saying that the truss rod nut is shorter. Do you mean that the nut is farther into the neck? I don't have experience with that exact Peavey, but do you or your dad have an allen wrench set?

The nut on the Pallaedium is probably further down the neck. I'm not sure, the TL-5 is a neckthrough, while the Pallaedium has a bolt on with some kind of angle adjuster on the baseplate.

The part you twist that is sticking out is longer on the TL-5, and that is why the wrench does not seem to fit.

We also do indeed have metric and imperial hex sets, not the 5/16's that is required though.

Also, thank you for moving this topic, which I assume you did.

I've seen the long TR nut prob on a couple of Peaveys.

I have cut off the Peavey thin wall TR tool, not to make it shorter for your purpose, but to get it to fit on the nut better. Over time the end will "expand" and not grip the nut. The cut off end needs to be squared up and de-burred with a file/sandpaper.

If you can get the nut off, it can be cut down. It only needs to be .400" long (about 10 mm) to do it's job. Use the end of the nut that is flat which goes in the TR pocket. The bearing surface that mates with the washer in the neck MUST be square with the threads inside the nut. Round over the other end with a file so the TR wrench will slip over it. Use the other end of the cut off nut as a pattern.

You may also be able to find some 5'16 hex spacers that is threaded 10-32 at a hardware store and make a TR nut. I've done that, too. Be sure and get brass.

If you cut down the Peavey tool and can loosen the nut, I've found that a #2 Phillips screwdriver, inserted with some pressure, into the hollow of the nut will unscrew it.

FWIW...I own four TL-5s of various flavors and love them.

Edit:
You could also use a Dremel with a small burr to enlarge the space for the TR wrench if the area would be covered with the TR cover. Dangerous, I know, but....

Thanks. Managed to romance the wrench over the nut.
An engineering compromise.

Adjusting the nut (now with a dab of superglue) will see if 1/5 turn is too much.
