Bent motor Shaft TD160

[enzedone]

I have just purchased a TD160 Turntable. It has a bent motor shaft. I was going to rebuild the TT and put it onto a new plinth, which was to be about 10mm thick. So i was thinking, would one of those new Rega upgrade motor kits for Rega 3 be o.k to use?
And if so, how would I work out the distances, sub platter to motor. I've never done anything thing like this before, so any help on this subject would be appreciated......cheers

enzedone,

I have never seem the P3 motor upgrade except here:
http://www.rega.co.uk/index2.htm

Keep in mind that you will have to make a new pulley to adjust the speed....
And I don't know the length of the axel, so be careful ...

The other way is:
3 years ago I did replace my TD145 AC motor with a OriginLive DC motor
and made a huge PS for it.. {now it can work from either 110 or 220 volts AC}

I had no digital camera at that time, but as I remember
the installation of the motor was real easy using the rectangular mounting plate
shipped with the motor, all I had to do was to install the regulation PCb with 2 screws
on a piece of wood glued to the plinth
and replaced the original speed switch of the Thorens with the 33/45 turns
switch provided.

You should find pictures of such upgrades on the originlive web site.
or some sites with Thorens turntables...

I did only buy the DC motor and did build a 9 Volts regulator
with a LM317K and 50VA 12 volts transfo

I will check that site out. Yes you are right about the pulley. At the moment i'm just throwing around ideas. I may have to just put up with the shaft as it is, and leave the TT in it's original condition.

enzedone,

I think I have a solution for you !!!

1)- without unmounting the motor, remove the pulley, get the axel streight
and remount the pulley, if the bend is not so important ; you should solve this easy.
Using a small iron tube to do that.

2)- Disassemble the motor, and eject the axel from the rotor, get it strait then reinsert it.
Just reallign the axel before reinstalling it, that could be the next option.

3)- I sold my motor for about 12 US only the shipping cost, you can find a replacement
real cheap...

Regards.
Alain.

PS: I sold my old Thorens TD145 / 220 AC volts motor 3 weeks ago
sorry.

Hi enzedone

The only proper way to do some straightening is to remove the motor and chuch the motorshaft in a lathe. Maybe a friendly lathe guy will help.

[enzedone]

thanks.

Alain, thanks for that website. very interesting, and lots of discusions on turntables.

Bulgin, yes you are right about that. I have already had the motor out to have a look. I would actually like to take the entire shaft out, but it would be very difficult to comletely strip it down. And the casing is joined together by the shafts that hold the motor to the plinth. So i would have to break those connections and find another way of attaching the motor afterwards.

Thats why i was asking if it was possible to use the sub-platter and platter, then just have another motor assembly. I will think about this for a while as I'm in no rush. I haven't even got a pre-amp to run it yet...........but thats a whole other story.....

I would love to by a nice motor from that site Alain highlighted but its waaaaaaaaaaaaay out of my league, with the exchange rate an all, I could buy another TT for that price.

Hmmmmmmmmmmmmmmmmmmm

Dear Brett,
I am the one who brought a TD145 motor from Alain.
I am living in Hong Kong with 220V 50Hz mains. I have e-bay a TD160 from USA with a 117V 60Hz motor (Pulley size smaller than 50Hz, I think.) which I have replaced with the one I brought from Alain. That means I have a surplus motor suitable for TD160 under 117V 60Hz.
I know 117V motor can be rewired to work under 220V and all you have to do is replace the 50Hz pulley from the motor you have to the one you get from me, If you like of course. And you can have a working wonderful Thorens TT.
Since Alain only charge me the postage cost for his motor, I too will only charge you only the P&P cost.
If interest please let me know.
Best regards,
And again thanks a lot, Alain.
CHOW

That is a lovely offer. So you are pretty sure about the re-wiring?

My pulley is in good order.

I would love to get this going.

I can be contacted via:

Brett

That's a nice compensation for having to work Christmas

Hi Enzedone,
I thing this one may tell you how to rewire the motor:

I am quite sure the one I have can be rewire to work under 220V 50Hz with a proper pulley.
