Do what it tells you to do in the owner's manual.

I still have the user's manual. It says nothing about maintenance such as lubrication of parts, etc
Hi
I have a TD160 Mk 2 of similar vintage as a back-up/project deck.
The principal maintenance tasks apart from belt replacement revolve around lubrication. The centre bearing should probably be cleaned out and re-filled with oil. Ordinary 3-in-1 is not suitable, BTW. The motor bearings (top and bottom) could probably also do with a drop of oil, though this can be a little more difficult to apply.
If the suspension still bounces well, it probably doesn't need adjusting, though this is the next stage in maintenance. My example came without an arm, so the suspension had to be set up when the chosen arm was fitted.
I obtained a maintenance kit from Joel Boutreux (ex-Thorens employee) via Ebay. His maintenance guide can be downloaded from Vinyl Engine, and offers much guidance.

Thanks. Where, exactly, is the "center bearing"?
HiThat's the one revealed when you remove the sub-platter underneath the heavy main platter. Depending on the version, this sub-platter might be metal or it might be plastic.
Some of these decks have a device fitted that locks the sub-platter in place, and this has to be defeated by undoing a small screw on the sprung chassis, reached underneath the deck (a pain!).
Once the sub-platter is lifted up, you will see the hole from which the steel spindle has just emerged. This is the bearing. Both this and the spindle should be cleaned, and new oil needs to be added to the bearing and also the spindle, before the latter is lowered back into the bearing.
The link shows a series of internal shots of a TD166 from The Analog Dept site. This is a later mark without the built-in tonearm and with a different (lower-voltage) motor, but much of the chassis detail is the same. Images and instructions for the TD160 are relevant,too, as the TD166 was a budget version of that model - though it was on the market for many years after the TD160 was withdrawn.

Thanks for that detailed response. It looks too complicated for my rather limited mechanical skills. As I said, the table has worked flawlessly for close to 30 years. So maybe it doesn't need lubricating. I had asked in response to reading about other Thorens owners lubricating their decks.
I replace the platter bearing oil and lubricate the motor about once per year or so. After 30 years of use you might consider cleaning things thoroughly before doing that, along with replacing the belt.
We don't have to be mechanical engineers to do this, but it's good to familiarize one's self with major sources of information. I would highly recommend closely reading the Analog Dept site and the Vinyl Engine tutorial linked above!
Regarding maintenance stuff to buy...I've used off-the-shelf oils and generic belts, a modern Thorens branded belt, and the maintenance supplies sold by Joel linked below. I prefer Joel's stuff, myself.
