How to dismantle Well Tempered for shipping?

My dear now departed friend might have replenished the damping fluid in his WT Reference arm with something having a higher viscosity rating than the original, which certainly could account for its overdamped sonics. He wasn't sure what he put in there.  This was a guy who was a mechanical engineer and who taught me a lot about audio; it was very sad when he started to fail mentally, and I miss him to this day. But the unstable azimuth would seem to be a consequence of its basic design. 

I used to hear the WT Reference tonearm in my friend’s WT Reference TT, many times. Eventually, when he was finally suffering from dementia, I had to help him install a new cartridge, which caused me to have to fuss with that screw under the base of the TT to move the tonearm to adjust P2S and also I separately adjusted azimuth for the new cartridge. The downstream equipment was Berning ZOTL amplifiers driving Acoustat full range ESLs, so not too shabby. My overall impression was that the tonearm made every LP sound "good" but not real, kind of homogenized. In trying to set it up, I noted that it changed azimuth as the stylus traversed the surface of the LP; it would slightly roll over, counter-clockwise. Overdamped, I think accounted for the SQ. I did not come away with the determination that I would go to any great lengths to keep that tonearm in service, but obviously others feel differently. And it's possible that the TT itself contributed to the coloration. I do respect that.

The hole is of course directly under the tonearm pivot. Nice right rear of plinth
