Default Best solvent to clean out main turntable bearing?

Hi folks.

Can't seem to find any solid answers to this, but I was wandering what the best solvent (available in the UK) is for cleaning out the oil bearing housing of a Garrard 401 (or any turntable for that matter) ?

Is white spirit or methylated spirit safe to use?

Many thanks,

- John

I use dry kitchen paper towel for cleaning the sleeve bearings of my turntable.

Yes, but do not drink either.

Meth is not a solvent for most oils, white spirit is. Lighter fluid would be my choice out of the things I've got handy. The chance of damage to something as hard as a bearing is small, just don't get anything abrasive in there, and don't leave any moisture.

...or you could use WD40.

For anyone reading this thread looking for more general advice, remember that *sintered* bearings absorb whatever they are soaked in. In this case, solvents aren't a good idea. A few hours soaking in a suitable oil (preferably heated) is all that's usually required.

Wouldn't think of it (hic!...... damn!).

Thanks for all the advice - will try the heated oil approach. I believe the bearings in the 401 are sintered (according to: http://www.slatedeck.com/turntables/...0Bearings.html)

What's the best way to heat the oil? Hair dryer, or perhaps placing the oil in a container, then placing container in boiling water, or something else?

Thanks,

- John

Thanks, I wasn't aware that sintered bearings were employed here...

Sintered bearings can be solvent washed clean, and should be, if the bearing has been allowed to 'dry-out'.

It will need re-filling with oil - best done as a heat soak, rinse with clean oil (to ensure all solvent is driven off), and a final heat soak.

The longer the better for both stages, and it will STINK...


Afterwards, wipe the exterior, and degrease the base of the bearing, before applying a new gasket using something like blue hylomar.

Add some oil, and gently insert main shaft - if you use the felt ring, it will soak up some of the excess, and ensure continuing lubrication...

Agreed, I meant that they shouldn't just be rinsed in situ, then a smear of oil applied, as one might with ballraces etc.

I just heat the oil in a small pan over a stove. I guess there's a degree of risk, but no more than in making chips!

In the end I merely poured the oil into a beer glass I had to hand (!) and put the housing in there, leaving it on the window sill - been so hot it's doing the job nicely. Will leave it a day more than clean it up.

Just hope I don't pick up the wrong pint glass..... the colour is exactly the same as a good ale
