Help!Truss Rod won't turn either direction

Discussion in 'Hardware, Setup & Repair [BG]' started by faulknersj, Jan 8, 2014.

  1. I have a 2001 Fender FMT V that has a stuck truss Rod. I have tried using force but it didn't budge. Any tricks or techniques I can try?

    Thank You!!

    Have you tried taking the tension off of the strings?

    Past that I have used penetrating oil with good results, but keep in mind if it touches finish or soaks thru the wood because to much got it there, it will leave a cosmetic issue
  3. yes....i took the strings off..but good point!! What kind of oils? WD40?

    Thank you!

    A drop of a high quality penetrant in the threads for a day or two might help - I like Kroil or PB Blaster... You have to be careful not to get any into the wood that the nut shoulders up to - otherwise, you might soften it to the point of crushing, then you have another problem to deal with...

    Another trick is to heat up the nut with a soldering iron - again, taking care not to damage the surrounding wood...

    I assume it doesn't move if you tighten or loosen it?

    Yes or similar. If it has rust on it PB blaster works good

    The one i had the worst trouble with was almost completely froze. I unstrung it, oiled it just a bit, wait a few hours and try to get it to turn either way. If not, oil it again and try the next day. Took mine a week before I could get it to back out.

    Eventually what i did was remove the nut, put a small washer over the rod, greased the nut and reinstalled. Worked good then
  7. Exactly. It is just stuck.
  8. Ok cool! I'll give the oil a try. I really appreciate the help! Thank you!

    What do you mean "back out"?

    If you mean that the neck is still not good when the nut is as far as it can go then put a washer on first before you put the nut on. Quickest, easiest fix.
  14. That is exactly it! Thank you! Is there a standard washer size for a 2001 Fender Jazz?

    The washers they sell at Drum shops for cymbals. Those fit, and work well.
  16. how do i get the washer around the rod so that the nut still attaches?

    Thank You!

    With the proper washer(or 2 or 3), you remove the nut, slip the washers over the trussrod end, and thread the nut back on... It's not an uncommon procedure on older basses...

    Fyi, if you just try to drop the washer down onto the rod you may have a time trying to get it to land right although if you put the washer on a screwdriver or similar and use that to feed the washer onto the rod it makes it easy.
