If you put a smaller pulley on the motor, I think 2" or 45mm is the smallest they make, it should slow it down just right. I also removed the brake shoes on my analog servo motor as well, made start up much predictable and smoother.

Nice looking machine, easily will last another 60 years. There is another recent Pfaff thread, there are some great links to information on the Pfaff machines.

I use 135 with a 22 needle on mine, works very well. Go here and search for manuals for the 1245. https://www.pfaff-industrial.com/en/support/downloads/technical/documentsearch The service and instruction manuals are what you want. I wouldn't get too hung up on the letters and numbers of your machine, yes, nice to know but you're never sure if it was changed somewhere along its life.

Give it a good cleaning, oil it up and adjust it. There is a manual for setting up a 1245 which can be used for the 545, plus there are copies of the 545 manual but honestly the 1245 manual is much better. Your problem looks like the tension is set wrong. The 545 is a great machine by the way although parts are sometimes hard to find and are usually pricey. Give this post a good reading as well:

I agree on the servo motor. I installed a Consew CSM550-1 analog servo motor on my Pfaff 545, held off with installing the speed reducer and have found it to be just fine. If you go with the Consew servo motor CSM550-1, two suggestions: 1. contact Bob at Toledo Industrial (advertised on this forum) 2. remove the brake shoes from the motor, it makes startup much smoother. I wrestled with going with the analog vs the digital servo motor and opted to save a little money by going analog. Sometimes I do wish I went with the digital so I could install a needle positioner. If you go digital, Sewquiet or Sailright 12 coil motor would be my choice. I've been using mine for some Jeep seats in leather, my next job will be an interior for my boat using vinyl. The Pfaff is a great machine, you really lucked out on that one. Let us know the specifics on the machine and holler if you need help, always someone here to help out.

I'm going to suggest looking at anything that rotates, any excessive clearance will make that type of sound on other mechanical things. Have you looked for excessive backlash in the gears underneath - and I'm assuming the Juki's ahve gears.

Glad it was simple! I had a 145 but was able to find a 545 very close to home in better shape. Finding a newer 1245 would be my ultimate machine. Overall they are built like tanks, once you set them up they go for ever.

Could the safety clutch do that if there is a bunch of thread wound up around the bobbin holder? My guess a good cleaning and adjustment is all it needs.

I have had good luck with this company: https://www.amazon.com/stores/ckpsms/page/8C8B8C59-BE53-42E6-B404-8E5D05BAEFB8?ref_=ast_bln&store_ref=bl_ast_dp_brandLogo_sto

You could adjust it for the shorter needles, the 190 system aren't very common, I had a 145 H4. The 135's are a little more popular but there is another that is used on the Consew's but I can't recall what it is, that might be the way to go. Good luck with your search.

Sorry I can't help you with a bar but have you thought of having yours re-tapped? I can't recall if it's a through hole but if it is, you can always insert the tap from the backside which might give you a better chance of hitting the original threads. If this isn't your cup of tea, maybe a friend who knows machinery can help you out? I think the thread is a M3.5. You might try this one: https://www.cutexsewingsupplies.com/products/cutex-needle-bar-part-number-91-710650-92-compatible-with-pfaff-145-335-545-sewing-machine?variant=42810286604531

I wouldn't take it all apart, just enough to get the gummed up stuff cleaned out. I have a 545, also had a 145 that was pretty dirty. I flooded parts with WD40 and 3 in 1 oil to get everything all cleaned up, especially on the 145. Search for the 1245 setup and adjustement manual, most of it will apply. I have a lot of documentation that I can send you if you want, let me know.

I see my photos didn't upload, wil get them tonight.

I have a couple more but I can't upload them right now.

Managed to take these pictures with a scale in the background, let me know if these are OK or do you want more.

Sorry, got home late last night and didn't have time to measure, will get to it tonight for sure.

No problem, I'll reply back tomorrow.

Mine is an H3. The presser feet are the same between the H3 and the H4.

I just received the presser feet set I ordered from Amazon for my 545. They are https://www.amazon.com/stores/ckpsms/page/8C8B8C59-BE53-42E6-B404-8E5D05BAEFB8?ref_=ast_bln&store_ref=bl_ast_dp_brandLogo_sto and are now the 4th set I have ordered from them. They fit just fine and I would recommend that brand. I did order a different brand last year which stated it would work with Pfaff machines, however it did not. I woudn't think ppresser feet are different for application, I can't see having to adjust your machine just to sew piping vs. regular stitching. Also, if you order from Amazon, I have found their return policy to be easy and fair.

Thank you -

Can you share the link for the diamond shape logo one?

I'm not trying to be condescending but have you tried looking for the correct presser feet? I had gotten an edge guide presser foot for my Pfaff and it would not fit even though the ad for said it would,. I could have made it work but I found another brand that worked perfectly, it too said it would fit a Pfaff. It isn't easy but you can find parts that will actually fit a Pfaff. CKPSMS was the brand that worked for me, I know they do have other presser feet that they say will work with a Pfaff but I have not tried them. Keep in mind the model number of the one that worked for me had 1245 in the part number which I take it to mean it would for a Pfaff 1245 machine.

I would agree with the previous posts that your machine probably didn't have one. If you compare your gear cover to the one in the video, there doesn't appear to be a place to connect the oil wick. If you open up that gear cover, I bet you'll find a blob of hardened grease and not oil.

Best source for parts like that will be on ebay. There was someone in Poland I think that was selling parts a year or two ago, not sure if he is still listing. New parts will probably be non-existant sorry to say and it seems only the consumable type parts are available from China. Keep looking on Marketplace and ebay for a another machine you could use for parts, they do come up time to time. Remember that the 145 and 545 are almost the same except for a few things, H3 and H4's are also very similar so you could expand your search for those as well. I had a 145 and sold it, replaced it with a 545 and am very happy with it. Good luck with your hunt, be patient and something will come up eventually.

The Pfaff 145 doesn't have any belts on the machine itself so you must be talking about the drive belt from the motor to the machine. Take your original one to Ace Hardware, auto parts store or even on-line if you can read the numbers on it and get a typical small engine 3L belt with matching numbers. The 3L is the belt width across the widest part, do not use a 4L as they are too wide and stiffer. They should last for decades, unless the machine has been sitting with tension on the belt which will give it a permanent set. There are also other types of belt you can use, some look like a round hose while others look like a leather belt with interlocking pieces. Do a little searching to see what's out there.
