Vintage DD turntables. Are we living dangerously?

A very nice system, chakster.

I am in the process of opening my PD-444, checking the boards etc. very clean I have to say.Should I lubricate (or try) the spindle from the inside of the motor? with synthetic oil? or I better leave it the way it is?
I just realized that loosing the screws of the motor you need to adjust it so the plate turns freely or it could get close to the actual plinth ...

This is certainly odd to say the least, I can't fit the motor back in a way the platter doesn't touch the plinth and turns freely, it came already kind of leaning towards the right by a millimeter or so but now it just won't fit properly, I wonder if I should use washers to keep the motor lifted higher and the platter higher too

My JVC QL-Y66F was making a bit of a clicking noise as the platter was spinning.  Not audible through the speakers, but didn't seem like a good thing.  I looked inside to see if some of the Plasti-clay I used to damp the plinth had come loose, but all seemed good there.  I put 3 little drops of oil in the bearing and mounted my Denon DL-301 MK 2.  No more clicking and it sounds a lot better than it did with the Shure V15 MK IV with the Jico SAS stylus.  

I have about $1000 into the turntable, cartridge, and phono stage and while it doesn't rival my big rig by any means, it would be hard to beat for how much I have invested.

Just found this by Lew

In addition to adjusting the screw under the bearing well in order to set platter height, one can also shim the motor up, if the platter is rubbing on the escutcheon. I found on my TT101, in the course of investigating this new noise issue, that my motor is shimmed by two very thin washers under 2 of the 3 fastening screws. Under the third screw, there are 3 such washers (or shims).

So I guess I have to play with the washers and get the platter higher and free of the "escutcheon" 1st time I have seen that word
