have you read specifications? Needle system: 134-35 LR Needle size: 80 -100 Nm Max. sewing speeds: 2.800 s.p.m Max. stitch length: 8,0 mm Top feed stroke: 7,0 mm Stitch type: 301 (Lockstitch) Thread type: synth. 40/3 Clearance under the sewing foot: max. 15,0 mm it also says max 3/8'' thickens. I am not used to imperial measurements sorry, but I guess you will be better at that. The name 335 suggest it's a clone of Pfaff 335. You can find a lot of info about that here.

you can also check the adler 68 parts list: https://www.college-sewing.co.uk/amfile/file/download/file/3091/category/498/

I wrote you a message with details.

Search on the forum, it was already linked here in few topics. Actually if you Google it, the first result leads back to a post from 2021 😀

There is one on ebay https://ebay.us/m/MZBMPe There are also some Chinese for a fraction of price (24$) that could maybe work. They don't have the sliding wheel on the top. I can do it for 70$ (knee lift) + ca 45$ shipping. But you need to wait at least till Friday when I am back home from a short travel. I need to weight it and check if it is really working.

According to Pfaff 545 Spare parts catalogue is the same as on Pfaff 138, 145 etc. I could sell one for a fair price (which I don't know yet :))) but I don't think there is a point sending it from Switzerland to Texas

When I was first cleaning it, I didn't know the know it is from Bakelite, so it broke in half. i glued it together and put it back it still hurts a little bit. But there is no magic behind it, it's just a simple know sitting tightly on that shaft. After you loose that screw nothing is holding it. Except old oil and dirt.

i can download the "BA Pfaff 138-1" than Hans has attached. I guess some kind of safety check is preventing it for you. Otherwise it is this one: https://issuu.com/davidmannock/docs/pfaff_138_adjust_manual

Frozen zig zag knob is a known problem on this type of machines, here is a video of solving the problem with Pfaff 130. Search this forum for Pfaff 138, there are already posts discussing various problems, including the one with ZZ know:

1) Check first the obvious part as it is written above: - is threading right, is thread moving through the needle, check threading through every single part, i.e. tensions disks, check spring assembly etc. - check the needle, is it bent or damaged 2) is the upper thread going around the hook? 3) check the needle position to hook and hook timing, I suggest using the old adjustment manual for Pfaff 1245 (the successor of 545), needle and hook timing is described in point 5, but I suggest going through everything: Pfaff 1245 Adjustment 89_09.pdf

I am using something similar, but without the spool stand (I am using the main stand on the table). It works without problems and very fast.

I will just give a few comments on Pfaff 145-H4 6/1c LMNP (as I only know Pfaffs) It's a compound feed, high throw H4 machine, i.e. 14mm under the foot at maximum lift. C is for medium to heavy material (C and D have the same hook). It has a safety clutch. The down size of 145 are small bobbins, the same size as those used in domestic sewing machines. This is not a problem when working on small jobs, but it becomes annoying when working on larger runs or with thicker threads. From the pictures I can see that someone has put some effort into the machine, it has a new upper tension piece and new cover plates around the seam length lever. But looking at the table and the pedal, it looks like it has been sitting in storage for a long time after leaving the factory where it was used hard for many years. But this is just my guessing :))) I have a few old Pfaffs and I service them myself. They usually run incredibly well for 50 or more old machines. The main problems I have are those that have been serviced incorrectly, mainly screws that have been over tightened. Some parts are hard or impossible to find, especially inside the machine. Feet, feeders, tensioners, bobbins, hooks and bobbin cases are still available, and you can get them either as original Pfaff parts, which are very expensive, or from China, which is much cheaper but of varying quality. To my European eyes, where Pfaffs are more common, $900 is a steep price for such a machine. I think the reason is that the H4 version is somehow very famous and sought after. As Kgg said, buying a servo motor would be a good idea and it will add to the final cost. Btw. if you are mainly doing marine vinyl, especially for the larger pieces, I think the flat bed is a good choice.

You never loop the thread around the pin. Pin is there only to prevent disks from turning.
