Default Thorens TD 160 Super:Transport Lock Screw

Hello,

Someone has given me a TD 160 Super that has been in storage for a number of years (10+ yrs) with its transportation lock screws fully
engaged. FYI, the person who gave me the unit is not familiar with its
operation, so I'm turning to this forum for answers. It did not come with a user manual (I've downloaded one from a web site) or any ancillary tools or maintenance supplies.

1) What type and size of handtool is required to unscrew the lock screws.
None of my mongrel assortment of slotted or philips heads seems to fit, and
having felt around with the tip of my finger it seems to be a very narrow slot or, since its diameter seems to be much less than the size of the access hole, I even wondered if it might need a socket.

2) Am I correct in thinking that in the lock down transport/storage state the springs are compressed? If that is the case I'm wondering if being compressed for so long might damage the springs. I'm sure I'll find out right away once my first question is answered and I'm able to return the thing to its normal suspended position - and see if the pulley is centered correctly, etc.

My audiophile credentials are entirely sensory - not much tech savvy here, so I hope you don't mind the low-end questions. On the other hand,
if someone knows of a source for a technical/repair/service manual for this turntable, either a free or low cost download perhaps, I'd appreciate the input.

Thanks,

...Tim

Hi Tim,

It's a slotted cheese-headed screw. If you can fit a reasonably long, flat-bladed screwdriver in through the holes in the baseplate, you should be able to undo the screws. A stubby screwdriver won't do it, though. It may require a bit of "jiggling" of the screwdriver blade to locate it in the slots.

I'm not sure how compressed the springs will be; at least they won't have been supporting the chassis' weight all this time.

Service and other manuals can be downloaded from Vinyl Engine (it says TD145 service manual, but the TD160 and Super were largely identical without the electronic end-of-side detection and auto-stop), or The Analog Dept's Thorens Dept.

HTH,

Mark

Hi you can even remove the bottom plate , then directly see these screws. After unloosening , you may have to check the alignment of the suspension - above vinyl engine link gives enough information
