there are many manuals on internet, but I couldn't fine something exactly for 169. Service instruction 69-343 DE-EN language than you have this post on leather worker forum: A German only service manual for Adler 169 and so on

to me it looks exactly like connectors used on computer power supply units and motherboards, this one on my picture is cable from motherboard to hard disk, or the 24 pin PSU ATX cable: you need to find 2 pin connector, sorry I don't know the name of this type, maybe someone else will jump in soon CPU-Power-Cables-4-Pin.webp

Strima use the same socket on their controllers (I use them), but it makes no sense to order only a few items from them (the transport costs are too high). I got something similar from Aliexpress, but the polarity was wrong, so I had to rewire it. You can also get these things on Amazon. The controller and the lights are generic Chinese products, they are all over the place, with different names and hard to know characteristics. So some guess/testing is required. btw. the title of your post is somehow lacking :))))

I know this is an old post, but for future reference, this one is threaded incorrectly, from the tension discs the thread should go directly to the thread controller. Do NOT go around the pin/post as in the picture above!

As I don't trust Aliexpress too much, I bough this one from Amazon: https://www.amazon.co.uk/Canilla-Machine-8-000RPM-Controller-Accessories/dp/B07SDP5FHB?ref_=ast_sto_dp&th=1 I run some small industrial machines with it: a Merrow butt-stitcher, a Yamato over-stitcher and a Dearborn blind-stitcher. Frankly I don't know if they are any different than usual ebay/aliexpress motors, but at least you know whom to complain.

If you check part lists of Pfaff 1242 subclasses, they go up to 72 mm. 1242 is double feed, feed dog and needle fed so it is more an upholstery than a leather-working machine. Btw I have one with a simple 4,8 mm gauge that I use for flat felled seam on fabric. PFAFF 1242 parts.pdf p.s. you didn’t wrote what kind of material and what thickness you would like to work with.

another thought: use needle synchronizer I have a 750W servo motor (brushless) with electronic control box and external synchronizer on the sewing machine. I don't know how many coils it have, it was the upgraded version, but it could be just a PR thing. The low speed is 100 rpm but what actually makes it great is the synchronizer. Pedal down > needle down, pedal up > needle up. There is no problem with speed as I can go step by step when I need it. The needle is always in the perfect position, when the loop is already made (down) or when the thread is unlocked and good to move (up). I used one table with the motor with different machines, each has it's own synchronizer fixed.

Here is a video of rebuilding the machine (in 6 parts) from a retired Bernina mechanic: https://www.youtube.com/watch?v=PVbA1gH1dWY&t=9s and here he is adjusting the Bernina https://www.youtube.com/watch?v=qoXRnmFJ2N8 but as far as I have seen, there is nothing about the cam box in those videos. Do you have the exploded view of Bernina 217: https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.supsew.com/download/Bernina/Bernina%20217.pdf&ved=2ahUKEwjVos3-l-OKAxUmhv0HHVz6MPQQFnoECA4QAQ&usg=AOvVaw1R4bnPRV_xIhOwSZW3inpU good luck, post the results of your work here :))))

Just google "Pfaff 145 parts diagram" and you will get all the links for pdf's of it with exploded views. I can copy a few links here but I think it's best if you pick the one that suits you best. When looking for parts I usually combine a few different ones, there were different editions. For my Pfaff 142 the best one is a really old one, but I still combine it with newer ones to check if the part number has changed. And to time it, I used the knowledge I gained with my 1245, where applicable. I cannot help you with the dismantling, for me finding missing parts, cleaning, oiling and timing is a challenge and I never venture far beyond what is necessary.

Just lower the presser foot bar and start using high shank feet. They work perfectly fine, but it's true, you need to press them on with some effort and precision. I guess, smaller tolerances, Germans love that :)))). More about lowering the bar is here, you just need to loosen one clamp: Here is my 138-6, original foot for comparison, and actually I can still use, as on my presser foot bar there are two holes for the screw. red arrow points the presser foot bar clamp.

if you think something is stuck around the hook mechanism, , I would first: - remove the bobbin and the hook, and check what is going there, you do it from the top If the screws 1 (there are two of them) don't wanna move you can achieve similar (disengaging the hook) by either: - loosening bolt 2 (they are on both sides) and then you can slide the whole hook/bobbin assembly away from the lower clog wheel - or loosening bolt 3 (there are two of them), than you can freely rotate without engaging the hook Doing anything of this, you will have to re-time your machine. And to time it, you need to be able to manipulate those parts (all the screws on the picture). Yes, you need the right screwdriver. Striping the screws will send you on the mission of where to buy them. You can guess how I know it :))) Get the exploded view of your machine and check how it works. btw. I don't own Adler, but my Pfaffs 1245 and 142 look very similar at least in this part. .

what is " vertical cam plate"? are you trying to achieve the full movement of feed dogs? Just asking because my 1245 also moves them only in horizontal direction and I haven't found that problematic. But I like to tinker with my machines, so I will follow your work..... My 1245 was retrofitted by previous owner from 190 to 134 35. I never bothered to buy 190 needles as I use 134 35 in two other machines and I don't need the additional height (similar use as you). Needles are practically the same, but 190 is few millimetres longer than 134 35. With my pfaff you only need to lower/raise the needle bar. A minor annoyance is that if the needle bar is in the lowest position, foot is set to maximum vertical movement and I raise the feet, the middle foot touches the needle bar.

I have a pdf with very nice exploded view, it's taken from here: https://www.occaphot-ch.com/bernina-info/kap-2-setting-service/ you have also some pieces of information here and there about cam mechanism. Download pdfs and read them, maybe they can help you.

I don't know if this are CAMMA disc, but they are for Bernina 217, I think you need to log into the forum to see pictures: https://www.naehmaschinentechnik-forum.de/viewtopic.php?p=119667&hilit=bernina+217#p119667 You have this overview: and also every single cam with a number:

I guess such price is because of free delivery, I guess Germany and France, and everything else is paid. Price to Switzerland is also much higher, 135 CHF
