Peavey Foundation truss rod help>>>> please!

Quick question. I am trying to straighten out a 80s foundation neck and believe I need to add a washer or 2 to get more action out of the truss. So I pulled the nut out (that sounded weird) and inside I see what appears to be some hollowed out and deteriorating wood....which makes some kind of sense because the truss is hard to access .......and below that a metal plate almost like a square washer.
So is this a standard part of the truss rod or did someone somehow jam a square washer down in there and try to fill it in with some kind of synth wood compound? Can I move forward with adding a spacer or 2 or has this neck been overabused? Any help is appreciated especially from you foundation heads out there.-- Sorry if it seems a dumb question. Thanks--Phil

You realize that a Gibson-type 5/16 wrench is necessary for adjusting the truss rod? First, try the proper wrench before attempting any alteration that will remove wood, or change the design.

See part #6106 (shown in photo). The design requires a bit more 'reach' than a typical truss rod adjustment.

If anyone told you it was stripped, it's probably because they were sticking an allen wrench in the hole.

Thanks Stacatto. I am using that wrench ( I think I actually got the link from you from another post---thanks). I turned the nut to where it seemed was as far as it would go ---I didnt want to really force it. It still needs to go perhaps a half turn further to get a properly straight neck....do you know if that is what the truss normally looks like under the nut? Thanks!

I recently went through the same issue with a T45. I removed the nut, stacked a couple of washers under it, no apparent change... Kept wondering about that exposed square section... hmmm... Finally decided to really put some torque on the wrench after lubing the nut with powdered graphite. Lo and behold it worked! Try just a 1/4-1/2 turn after you feel the tension kick in. Tune to pitch and check action. Good luck.

It is a bearing plate. It spreads the load across the end grain of the wood to prevent crushing the fibers. It allows for more compression of the truss rod. Standard equipment on all truss rod assemblies.

great thanks guys

Definitely add 2-3 small washers. The rod has a limited number of threads, and the extra spacers will help. Lube the nut before replacing.

As well as the washers mentioned, back clamping the neck into a backbow will help this problem.

Update: I finally found some washers to fit in there but they were not the standard size but rather lock washers that I bent into straight. I don't think standard wahsers exist that would've fit. Anyway, I added two, adjusted and bang...the neck is more or less straight. Thanks for all the help people. Pretty easy process!
