Micro Seiki RX 5000

Many thanks to your helps.

I think is one is not the air bearing I can't see any privided hole for air line underneath, and the platter and bearing spin OK.

Hsindo, I don't know the size of the screw, it's just metric ones.

The unit came with Thorens mat but I removed it and it now looks disgusting like this, so I really need to split them to clean to aviod backache.

Can anyone also tell me how to remove that 15 years double sided adhesive tape, particularly on Micro platter?

Goo Gone(denatured alchohol) if this doesn't work mineral spirits. Lacquer thinner can be used but be careful of any surrounding finish.

You could try WD 40 and let it sit there till everything softens and hopefully just wipe off with a paper towel. It should be safe and non corrosive.

Goo Gone will work much better than WD-40.

This is an excellent TT -- but the screw suggestion is likely to mar the gun-metal of the platter -- this is a pressure fit only. The trick is to heat the platter. Put a towel on the platter an pour boiling hot water on the towel. It should (maybe with WD-40) lift right off.

A note on the bearing -- Micro-Seiki used lead (Pb) "powder" in their oil -- it is very toxic, and should be handled with care. Before you go through the exercise of removing the oil and changing it, you should listen to bearing housing base with a stethoscope -- if the bearing moves freely,and is not noisy, just use it as is. Otherwise you will need to replicate the same original treatment - and use powdered lead (Pb) [available here - www.testbourne.com/materials/metals-details/3523-640/Lead-powder/ ] in your replacement oil. This is due to the spacing in the bearing, and I am not sure if graphite powder would be a good substitute, as graphite might etch or corrode the stainless steel -- whatever you do, use a "high molecular weight" oil -- or an impregnated one.

These are best driven with an aramid (Kevlar) string -- you can buy a 600yd spool at Edmund Scientific [scientificsonline.com/product.asp_Q_pn_E_3034863]

Enjoy -- I would also invest in this record weight -- TRITIUM POLISHED BRASS COPPER RECORD Clamp -- look on ebay fo it -- it REALLY makes a huge difference.
