TP-16 arm lift issue

Post by colver » 13 Feb 2016 13:08

I have a problem with the arm lift on my td125 mk2. I cant get it to rise and lower much that its any use. Does anybody have any experience of such an issue of the TP-16?

There are three springs on the underside...be sure you have all three there. Just open the bottom (with care) and you can look right into the apparatus.

Check springs before messing with anything else.

Hi Colver,

AFAIK, there are no hydraulics into this system.
What are your symptoms: drops too fast or too slow? or not at all? Is it the shaft sticking inside the tube?
You can open/disassemble the mechanism if you are a good DIYer, but it is a PITA to reassemble it with the springs at the right place...
The one I fixed last month dropped too fast, so I smeared a tiny drop of silicone oil on the shaft and it worked OK.
The shaft is kept on top position by the horizontal spring #2.
Hope you can make use of the attached pic.
Cheers,

Hugh.

Hi Hugues many thanks for your reply. I had a half hearted go about a year ago to fix the lift but ive decided that its time to make a big effort and get it right. Im going to give it a go at the weekend, your instruction pic will really help, many thanks. Will let you know how things go. Cheers. Colin.

Hi Colin,

My pleasure!
The best you can do is have a look at the beast and find out the origin of the issue.
Do not hesitate to call if you encounter any problem.
Cheers,

Hugh.

Hi Hugh, I managed to get the arm lift working. It was the wire that was sticking inside the the outer cable. A bit of moving back and forth with some 5W-30 oil has done the trick. HOWEVER! I have another problem. The lift should move slowly up or down but mine is either instantly up or instantly down. Lowering means the stylus drops suddenly onto the record or or raising means the arm bounces up into air. If I move the slider button gently then all is well but its relying on me to do the controlling with a steady set of fingers. Any ideas?

Colin.

I would try applying a tiny droplet of viscosity 300 000 silicone grease on the internal shaft then making it slide up and down several times.
This grease is available from most hobby shops: it is used to lube the Scalectric type model race cars diffs.
You should be able to apply the right amount by the trial method. Start very sparingly.
Other turntables use the same stuff for their cue lifting system (Dual, Lenco etc.)
Hope this helps.
Cheers,

Hugh.

Cheers Hugh will try that this afternoon. It is bone dry so what you say really makes sense. Oh and while im here, whats your views on Thorens 110, 180 and 280 turntables. Im looking to pick up a budget Thorens and these seems to be the cheaper end of the market. The 280 tends to be dearest and the 110 the cheapest at normally around £50 -£70. Many thanks. Colin.

Hi Colin,

It was my pleasure to help you with your TD125 issue... and quite easy because I just had one from a friend of mine for repair/servicing. And it had the same issue.
My knowledge about Thorens is limited to the ones I had the opportunity to repair: mostly my own, both a heritage from a close friend and my late Dad (a TD166 and a TD146)
So I'm afraid I cannot really comment or advise on other models, especially newer ones.
Maybe someone else will jump in and give you the answers...
Cheers,

Hugh.

hey Hugues TR4. I have a TD 166MKII with the same issue, cue lever drops the needle like a stone... I've read your instructions on fixing this on another model. might this apply to my TD 166 MKII as well? if so, I'm not familiar enough with the inner workings and part names to determine what you mean by "internal shaft". can you possibly point this out in your photo?

"I would try applying a tiny droplet of viscosity 300 000 silicone grease on the internal shaft then making it slide up and down several times."

thanks!

<t>Hi Chris,<br/>
<br/>
As you can see on my pic, the arm rest (the horizontal black plastic part) is attached to a shaft which slides inside a tube.<br/>
If you are afraid to open up the beast, try and introduce a droplet of silicone oil as mentioned on the side of the shaft.<br/>
Then make it work up and down manually to spread the oil inside.<br/>
It is also possible to reach and clean the whole mechanism and smear fresh silicone (beware: too much of it will over slow the lift system).<br/>
Did you download the service manual from the VE library? Could be useful before you start disassembling (have a look at page 4)br/>
Hope this will help.<br/>
Good luck and Cheers,<br/>
<br/>
Hugh</t>

PS: sorry for the text of my reply. Just tried to save the draft while looking into the library.
Hope it's clear enough though!
