Lubing TT -- What to Oil, Grease, and Leave the Hell Alone?

[ignis-fatuus]

I've been going through a couple of TTs I picked up used--in some cases very used--and I was wondering if anyone can give me some tips. I'm generally more comfortable with troubleshooting and maintaining electrical components and could use some advice on what parts to oil, what to grease, and what not to touch or maybe just wipe down and clear of dirt and debris. Currently I am working on a belt-driven Philips GA-212 but there are other TTs in the cue which are direct-drive driven (Realistic Lab-400, Pioneer PL-400, Technics SL-3300). I have picked up some SuperLube grease but I have been unable to find any SuperLube oil locally. I did pick up a bottle of sewing machine oil as it has a low viscosity and penetrates well.

Attached are a couple of pics of the Philips 212. There are a number of assemblies with moving parts of which I cannot see a hint of lubrication or having been oiled or greased:

a) Plastic linear gear mechanism left of the LDR interrupting swing arm assembly
b) Tone arm assembly (top of TT) and connected LDR interrupting swing arm assembly (Inside TT)
c) Motor driving the belt and spindle/platter
d) Spindle (top of TT) and bushing assembly (inside TT)

Reading through the two service/operating manuals I found online, I see mostly electrical adjustments and servicing with little to no reference to lubrication--or such is the case with the Philips TT I currently have upside down. Any help, tips, or advice would certainly be appreciated.

Failing info in the service manual, at a minimum I'd expect to need to pop the sub-platter out, clean the bearing well out, and put some fresh oil in there. Light machine oil of most types is fine. 3 in 1 electric motor oil, hydraulic oil, sewing machine oil, that sort of thing. Usually don't need much either, just a few drops to leave a film in the bottom of the well is all it takes.

If nothing else looks like its got any evidence of grease or lube, leave it that way.
