My 1019 is in need of some TLC due, mainly, to non-use. I have downloaded the Service Manual and three files: Repair Stand, Motor and Cam. I am in awe of the time and effort put in to create these service instructions. My question is are there any more of these files?

Thanks for what you have done and what I have found.

I know this response is a bit late, but make sure you also download the official Dual instructions and service manual for your turntable: https://www.vinylengine.com/library/dual/1019.shtml.

I have been reading through all of this and I cannot seem to find which idler wheels on which units. Mine is a 1019 and the idler wheel is cracked and in bad shape, I suppose it’s from incorrect handling in the past. Any help on what idler will work would be a great help.
Thanks.

This is what you need. You will have to follow his directions on returning your old one for buying his new one. They are rebuilt with new rubber tires. http://thevoiceofmusic.com/catalog/part ... ategories=

Dual 1019 continuous repeat problem notes.

My 1019 was repeating instead of stopping in single-play mode. The main cam has two paths and which path is followed determines whether the tone arm repeats or stops. Referring to the 1019 service manual it is the cam follower (137) position that selects the path to follow. And it is the change lever (195) that moves the cam follower to the stop position.

Now the service manual says to correct this problem you should “re-adjust [the] the change lever”, but offers no info on exactly how you make that adjustment. To be clear: you bend it. After spending at least an hour reading, looking, searching, thinking and watching the mechanism over and over as I cycled it by hand I wondered if I could just bend it into the position described in the manual. Yes, you can. Apparently in this case the meaning of “adjust” is “bend forcibly”.

After making this adjustment my 1019 is shutting off correctly.

I have successfully serviced the motor on my 1019 following the procedure outlined here. My question: the copper thrust plate is badly worn on both sides, so flipping it over isn't really helpful. Is there a source for this part or is there a suitable substitute part that I can use? Small polished copper discs are not that common.... Thanks for any advice!

I have successfully re-polished a copper thrust plate by rubbing it on various grades of sand paper (starting with grit 150 to finish with grit 1200), rather time consuming but giving good results.
You can fine-finish it on grade 000 steel wool and make it shine with some copper polish.
Very good results so far.
Hope this helps,
Cheers,

Hugh

I followed the service manual and substituted some of the lubricants with modern lubes with great success. It sounds great, my Father would appreciate what I have done for it to keep it going and in the family.
Thanks for all the help and leads on everything.

Following the advice on this forum, I now have a 1229 (mine) and a 1219 (Christmas gift to the parents) in great working order.
1219 - new dearing ring, new steuerpimpel and washer, relubed motor, rewired, old grease removed and regreased, etc
1229 - straightened tonearm, new steuerpimpel and washer, old grease removed and regreased, etc

Thank you all!

Substituting modern lubes can be ok I think BUT - PLEASE make sure that old stuff is FULLY removed first and also, please don't ladle replacement lubes on with a trowel as is common with many who've never done this kind of thing before.. A 1219/1229 is NOT the place to learn one's servicing skill - buy a cheap old Garrard/BSR whatever to practise on first - plenty of factory applied grease-now-glue on old late 60's/early 70's Garrards!

In any case on 12** onwards decks, mrow2 here (Don) has replacement gadus alvania grease, black rubbery pimpels to suit most later decks, the 1219/1229/1249? parts and a great basic servicing sheet with instructions.

Couple more reminders - dualcan.tumblr.com for pictorial stripdowns and other articles on servicing motors, cams and so on. Also, some new original parts.

Also, organdonorparts.com for good used parts and many not on the site if you ask...

Yet another 1219. Following the DIY guide, as previously, I am servicing the motor. I find there is no "circular plate" in the bottom bearing assembly, for me to reverse before re-installing. I seem to recall doing that, last time I did this.

There is the copper colored "springy" deal, the bronze sintered bearing, one large and one small fiber "rings".

Did I lose it? The plate that is. Come to think of it, none of you could judge that one in either sense . . . so, never mind.

The question becomes, is there supposed to be one in every motor? I do have one earlier model 1219 that I could from which I could salvage a motor, either to use, or just peruse . . .

AFAIK, there is always a copper disk in the bottom of a 1219 (as well as 1019) motor.
I usually turn it over when servicing. If it has been serviced before, it is always possible to re-polish the best side by rubbing it on a piece of fine grit paper (500-600-1200) in order to get the surface smooth and flat again.
Good work!
Cheers,

Hugh

I suppose this plate is now "unattainable"? Did not see it called out in FSM.
