iI saved up and installed a Kinedyne on my 545. I cannot recommend it enough and I simply cannot recommend the cheap chinese servos.

I've heard of people stuffing a pillow or foam to act as a stop too. NIce work on a good old workhorse!

Well I took a chance and ordered an aftermarket one. A Pfaff runs well over $100 if you can even find them. There is a post on this forum that states it's the same case used on some Juki's. Hopefully the one I ordered will fit and will work. If it does, might order a couple more just in case.

Found my bobbin case has a groove worn into the case and the spring, that would explain why I could never seem to tighten the bobbin thread. Can anyone suggest a supplier for a new one? Curious too if anyone has tried an aftermarket one or is it something you would only use a genuine Pfaff part for? The number is 91-08 348-91 for the complete case and spring. Thanks -

I had thought about a Consew but went with a Kenidyne, a bit pricier but a fantastic servo motor - it will go down to 50 rpm, probably the best and most helpful thing I've bought besides my machine. And I do not get anything by mentioning them. Finding info is a bit time consuming but it's out there, look for cowboysew and hightex - and no problems with running the needle positioner once you program the controller to use it. The motor doesn't care if there is one or not, it's all in the controller.

You'll see a difference, assuming you ordered a 45mm? Don't forget you'll also probably need a smaller belt too. Check your safety clutch on the machine to see if it was tripped, that was the problem with mine when i bought it.

Mine is a 545-H3-6/01-CLPMN. I also just installed a Kinedyne servo motor that runs as slow as 50 rpm, talk about control!

I am so very impressed with your restoration, fantastic job. I thought you were in Europe, the part availability seems to be much better there than here in the US. I looked at the decals, unfortunately they don't have any for my model.

You've done a beautiful restoration on your machine! I have a gently used 545 that I think is a wonderful machine. I'm surprised that you found the parts for your modification, I rarely see anything for Pfaffs. Where did you find the decals?

Not exactly creep but the ramp up speed is so slow it almost feels like it. The creep you mention is what I would call slip. With my motor and synchronizer, it's set up where I can get one stitch per tap on the treadle. I think buried down in the settings, I can adjust the speed as well. I don't want others to think I'm promoting one brand of motor, but if you search in my previous posts and then do a little research, you can find out more details from others to see the motor in action. After that, then you can make your own decision.

1) change the motor pulley to the smallest you can find, usually 45mm 2) go with a larger pulley substituted for the handwheel 3) speed reducer 4) I tried 1 and 3 above, ended up getting a different servo motor that would start at 50 rpmand not 200 or 300, game changer -

Pardon if my terminology is incorrect but I would like to change from a knee operated presser foot lift to a foot operated lift on my Pfaff 545. I find the knee lift to be hard to operate without having to readjust my body position to gain a little more leverage to push on it. I have no problems with the force of the foot on the material and I don't think I can reduce the presser foot spring force any more - it has a double horizontal spring across the top which is at its lowest setting. I would like to have the lift separate from my main treadle pedal so adding a second pedal or button would both be an option. Just wondering if anyone else has done this -

I can understand the desire to make something, good luck with it. Keep us informed, might be something others would like to have.

Get yourself a Kinedyne needle synchronizer for accuracy but I'm pretty sure the servo motor controller is what really controls the functions, the synchronizer is just a switch to indicate where the timing of the machine is. The Kinedyne is an optical synchronizer and is super accurate. http://kinedyne-motor.com/products/HM-750SH/234.html You could just get the Kinedyne motor and synchronizer and be done with it. Just sayin - Talk to Ryna at http://www.neelsaddlery.com/ I have no affiliation with Kinedyne or Neels Saddlery, just a very satisifed customer.

Wizcraft is correct, my needles are the 134-35 as well. My machine model is 545-H3-6/01 CLPMN. Mine is for leather so that might explain why I have two leaf springs on mine as opposed to your single spring. Other than that, I think we have very similar machines.
