I can help you. Is it on a treadle stand? Do not need any oil or grease in the oil boat on top if you are using nylon or polyester thread since most come lubricated. You are looking for a one piece servo motor. Not sure what is available in Europe. If in US, I can tell you. You might check with Strima in Poland to see what they carry. You will need to have the motor come with a 45-50mm pulley on it. No bigger. glenn

You can gear the servo down. Make sure it has a 45-50mm pulley on the motor. There is a way to make the balance wheel on the treadle stand into a speed reducer. I can walk you thru it. The lobes on your bellcrank are worn. That is why the stitches are so small glenn

You can order a synthetic roller on line from amazon to replace the stone feed roller. It does not grab as tight as the stone one and I found it works better. Not expensive. try one. I also replaced the foot with that roller foot. It works better on thin leather. These machines are touchy so once it is set, leave it. glenn

That is the set up I prefer. glenn That is the set up I prefer. glenn

Not wax pot, oil pot. glenn

Most 441 machines are mounted on an off the arm stand be a H legs or Weaver stand. I prefer that set up up. You want to hang anything off the arm to sew, you will find problems in your current set up. glenn

Only if the thumb screws to mount the binder are hanging down below the slide plate. Glenn

Made that way so feed dog does not lose contact with the binding. glenn

The bobbin case. Machine has no feed. needle goes up and down. makes stitch. you move the item by hand to darn up a rip or hole. glenn

is he looking for Needles? glenn

Would not be hard to build this. You need a round shaft, collar, spring, washer, cotter pin. Or call Collier Equipment or Bob Kovar at Toledo sewing and see if they can get the parts. part # rod #223684 collar #227227 screw #200113 spring #206628 cotter pin #202302 glenn

Machines without the P have skiff feed: Feed dog moves back and forth but never drops. Used on the 335-17 binding machine for symmetric feed. 4 motion drop feed is this: Feed dog comes up to meet the needle (1)and inner presser foot. (2)then move to the back, (3)drops down and then (4)comes forward before moving up again. Also called elliptic feed. glenn

You could sew leather with it. glenn

Yep Sorry about that Wiz.

Ccwboy Class 4. glenn

Were they made in UK? US? glenn

call Manufacturers Supply in St. Louis. They sell clickers. See what they say. glenn

Same manual will work. The 372 has smaller fittings on it like feed dog, feet. It uses smaller sized 134-35 needles. glenn

Nice work C!, glenn

The 335 can sew #138 thread. You just have to make a few modifications. Enlarge hole in inner foot and feed dog. Pfaff made a heavier take up spring. I would install that as well. I also went to work on the gap and finger on the bobbin area to have more clearance for the thread to clear on each stitch. glenn

Nice find C!!! glenn

Y The speed reducer screws with the sensing in the synchronizer. You can use a servo motor, synchronizer and speed reducer but not all three. I would get rid of the speed reducer. glenn

I would have the piece in the back welded first to see if it will work. Strima in Poland carries a lot of older parts. Check with them since you already have the part numbers. I you contact Pfaff in Germany and see what they have. There is also a guy on eBay in Lithuania that sells a lot of older Pfaff parts. glenn
