contact Collier Equipment in Alabama. They might have what you are looking for. The 91K5 Singer. They get good money for those.

if you install a needle positioner, you will need to order a plug from DA to mount the synchronizer on. I have the part # if you need it. glenn

Pic of the machine please so we can see what it is a clone of. glenn

Why replace the wheel? You want to slow the machine down? A servo motor will do that. I have a 669 with a servo motor and a 45mm pulley on the motor. You could add a speed reducer to slow it down more. However, with the speed reducer, you cannot add a synchronizer to the balance wheel because it screw up the sensors in the needle positioner part of the synchronizer. My runs as slow as I want it to. I also got a 669 from weaver. it is an Eco model. I added air foot lift to it. glenn

Damn!!

I have original Adler springs and clamps. Not cheap. Spring only $95.00. You can buy a new the leaf spring , clamp and screw from Adler as an assembly only. Last I checked $126.00 and change. glenn

Model of machine? glenn

I have tension springs for the bobbin case. Also, does your machine have a tension spring in the needle bar? Check it. glenn

I have used it before. Nice stuff

Gorgeous rebuilds! very very nice. Hammertone paint? glenn

ok depending on what gear you are fixing. Forward glove repalming, Pfaff 335 or a clone of it. Other articles would be goal pads Adler 205-370 or clone, Juki 441 or clone. walking foot single needle post Pfaff 195, 595, 1295, clones, Adler 68, 168, 268, Juki 1610, 1710. Flatbed walking foot. Lots to choose from. I have been build and repairing goalie hockey gear for over 50 years. I know what you need. PM with specific questions. glenn

if he replaces the motor, he loses the auto functions on the machines. Both motors are -7 which means they have toys. I would go the route of a phase converter like Uwe said so you do not lose those functions. glenn

OK. watch a few utube videos on changing belts on singers. Pfaff much the same. You have to remove the balance wheel, and the bushing that the main shaft goes in. glenn

The 291 was Durkopp's answer to Adler 767. When Durkopp bought Adler about 20 years ago, the decision was made to keep the 767 over the 291. Both are great machines. The problem was the threading of the 291 was Micky Mouse compared to the 767. It is a weird way to thread it. DA used some of the features off the 291 in its design of the 867. Specifically the trimming system for thread cutting. The 291 will sew heavier than the 255 but bobbin is a little smaller. glenn

please post pics of your Adler on the stand. That will help, Uwe, what is the cylinder arm machine on the floor in the back in your photo? glenn

Pfaff 1425 should be close to the same as the 1445. glenn

Buy the Consew. Better machine. Never been impressed with Sailrite machines. I think they are overpriced. I have been sewing and working on machines for over 40 years. Consew the better machine. Better built. glenn

Scorpio Leatherworks, See if you can get a one piece servo motor in Europe with a 45mm-50mm pulley on it first. Let me know and we can go from there. glenn

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
