Actually there is no need to remove arm pipe from bearing. Its unwarranted. I noticed it later in the process.

I loosely filled that cotton sleeve inside tonearm tube.
I am looking for tag board pins which we used in school days for making learning diagram. But seems unavailable now. These could make better joint IMO. I will post update once done. Then I plan to remove that PCB.
Initially my TT tonearm has good and well aligned bearings. So I took some epoxy hard glue on tip of wooden toothpick and quicky applied to area where inner screw and locking ring meet. That fixed position of locking ring wrt inner screw. Then I marked current position of locking ring and opened it with help of tweezers. That's it. It came out along with central screw. It wasn't that tight enough and I put it in same place just at place where play diminishes. Also listening helped to find it its not too tight.

I never touched my bearings. I did remove the arm tube to make it a bit easier to shrink wrap and stuff.
You are correct! Actually I realized this at the time of fitting it back and getting it right. It was royal pain.
That is why I am telling to avoid removal of bearing screw for rewiring. Its not required. Tonearm tube can be removed with those tiny screws at the bottom. No need to remove bearing IMO.

Good advice. No need to undo the bearings. Most of the Technics, anyhow, seem to have a dab of a Lock-tite type material on them anyhow. They are precision set at factory, and while I'm not saying it's impossible to re-adjust, there's typically no ned to (unlike many Jelco and Sumiko I work on).

Did the rewire and tonearm dampening, but I didn't remove the arm from the gimble. It took a while, but I completed the process in about 2 1/2 hours. Now, unfortunately, I have a noticable difference in L/R balance. I think I've traced it back to an azimuth problem. I checked the level of the armtube and the headshell with a level, and sure enough, both are off. I've been twisting it back to get it somewhat level again, and althought the sound is getting better, the left channel is still noticeably louder. I'll see if I have any mono tracks that I can use for more tweeking today. If I were to do this again, I think I'd leave the tube in place. Any advice would be welcome.
