Durkopp Adler 205-370 Handcrank

Recommended Posts

I came up with a basket-case Adler 205-370 that had set out in the weather for a lengthy time.  It was locked up tight, but still had all of its parts.  I began the process of restoring it to useable condition back at the end of August 2018 when I removed the active Yellow Hornet nest just inside of the top inspection cover.  I had hornets everywhere, and managed to keep from getting stung.

Once I settled back down from that experience, I applied Lilly White sewing machine oil using a syringe and a small Singer squirt bottle to what I could reach easliy, and let it set.  I oiled all of the keepers for the covers and feet, and after a few days, I removed the remaining covers to get oil further into the end of the head.  Every few days I applied more oil and checked the hand wheel for movement.  On the last day of November (3 full months later), I got the first tiny movement of the hand wheel.  I oiled everything again and worked the hand wheel back and forth then with more frequency, and finally got one full revolution 5 days later.

With both upper and lower shafts free, I turned my attention to the outer presser bar that was still seized tightly in the tension adjustment thumb nut.  After lots of oil and some heat from a hair dryer, I hadn’t gained anything by the middle of April (4 more months), so I gave it a big shot of PB Blaster, let it set for a day, and got out the Vise-grips.  I hadn’t broken anything yet, but that thumb nut was going to break free or be destroyed.  One firm twist of the vise-grips and the thumb nut popped loose from the presser bar with no damage.  On April 25, 2019 the machine was totally free with everything operating as it should.

The tension and pretension assemblies came to me in a sandwich bag and have been cleaned and reassembled.  I didn’t take any other linkages apart.  I have set this machine up for another mending and repair machine for my business.  The bulk of my mending is woven or vinyl materials.  The machine came with a #230 spacer, and I added a 7x3-26 round-point needle, Tex350 Bonded Nylon thread, new #28092 bobbin, set of Weaver harness feet, and a #22209 Agri-Direct Spinner knob for propulsion.  It sews just fine, and other than still shedding excess oil that I put in/on it, it’s ready to tackle its first mending job.

Thank you to all of the forum people that have talked about and provided videos about DA205-370 machines that helped me get this machine going again.

Great looking machine for sure.  Any work that you put into it will be well worth it.  Very desirable machine.

Thanks Greg.  I’ll probably use a little sewing machine oil to rub the painted surfaces to see if I can get any more of the rust stains off of it, but that’s probably about it.  I’m not too much into aesthetics (as you can tell by looking at my machines).  I’m much more into function, and will be fiddling with the tension and pretension assemblies as I go.  I know that it has definitely been over-oiled, and that could cause problems down the line if it’s allowed to set idle.  I have it near a traffic area and can give it a few cranks whenever I walk by it to keep it limbered up so that the oil doesn’t dry out.

It’s missing one of the springs in the race, and has one shorter replacement spring that doesn’t match the other two (one of those is bent).  I’ll be looking to get a new set of them (part # 068 00 183 0)?  Do you have those?
