1215 shut off issue

Post by Studio59 » 17 Jan 2019 03:39

Greetings fine citizens. I simply cannot get the switch arm(s) to move freely enough to shut off motor at end of cycle. In the experience with some of you who have encountered this seemingly common problem before, is the issue typically with the grooved shaft that the arm pivots on? I cannot get the shaft to unscrew or budge even. Many thanks.

Hi,
That central post (1215 item 180) in a common problem for all the Dual changers because of their age and the extreme hardening of the Alvania lube used on that spot.
The best way to get it out is to remove the two top items (177 and 178) first.

Now you can get alcohol further down on the shaft and let it work in.

You can also use some heat but be careful of the cam if you did not remove it. The cam also comes out very easily if you remove the three items on top , 25,26 and 27.

The complete bridge 201 with cam 223 comes out as a unit.

Don't forget to remove the counter nut 28 up top for 180 first!

Obviously the best is to do a complete strip down as all the lube points are dry and to that end I have the complete 1215 restoration on line, but for some reason it seems not to be linking at the moment.

In the meanwhile, take your time- it will come out!
Regards,
k

Many thanks for your response...with images no less! Confirmation of this procedure is very helpful and makes me feel much better I wasn't on a wild goose chase. I might as well take out the cam and clean it all off. That being said, might you be able to recommend a source for at least a few of the many lubricants indicated by Dual? Many regards, michael

Hi Michael,
Alfred (dualfred) has a complete set which also uses the lube numbers as you see on page 22 of the manual,

Perhaps dropbox might let you in on my 1215 pictorial:

If that works, let me know please.
Regards,
Klaus

Hi Klaus, I was indeed able to view the dropbox files, and they were helpful, even as though they were for the 1219. Same shaft and other components. But with regard to the 1215S, the correct position for the long barrel spring that goes over the shaft is still a question for me. Additionally, after very thorough cleaning, although slightly improved, the switch arm still fails to travel far enough on it's own to defeat the switch. Spring seems applicable here. Unfortunately, tightening the shaft snugly only seems to bind the switch arms considerably. :roll: Thanks also for the link to lubricants, as I am limited in resources at the moment to alvania, lithium and very light bore oil.

To anyone else and Klaus who so graciously assisted, I'm happy to report that after some effort, the deck works properly now. With this shut-off issue it seems that there are 2 main issues: Cleaning the main shaft is prominent, and getting those off is difficult but necessary. Only after I had applied heat to the shaft could I get the arm off. The shutoff arm still would not travel far enough until I completely disassembled and cleaned the speed selector assembly. Sometimes Duals can make one crazy, but a little patience and perseverance pays off.

Hi,
Precisely because these old lubes are so tough is why nowadays I strip the units down and rebuilt.

Every linkage that has grease or oils applied has more or less the same problem. By stripping the units, all parts can be cleaned and once re assembled will run like originally intended.
It does seem daunting for the first time, but so is continually finding another hard lube problem and never really getting it done all the way. The key is to work in group sections, (drive, auto system, tonearm with sound wiring etc.) which helps to keep things in order.
On my web page I show approximately 18 different models, all getting completely restored. Hopefully these guides can Help in the process.
Regards,
k

Thanks Klaus! Hey, I am wondering if that rotating clamp device is an item one might find on the planet without too much difficulty. Thanks! michael

Hi Michael,
If you are referring to the repair stand, then no, the stand pictured you will not find easily because it is a Dual manufactured stand meant for internal use in its service organization. For sale, Dual manufactured a collapsible stand of which the oldest version from the 1950's I still use today as well:

and the very last one they made, KDW 344 :

Because these are no longer made or very hard to get, I have designed a plan for a DIY stand which is also in the Dual Service thread on top. This simple wooden stand works nicely and can be made relatively quickly and inexpensively.
Here is a sample that our VE member Hugh made and is using to repair a PE Rex:
