Found in an old barn - Pfaff 545-H4

[Uwe]

My Pfaff 145/545 PDF manual (Pfaff 145 545 User Manual.pdf) has some service training info appended at the end. It's not quite a full service manual, more like a handout for an instructor led training class, but it's better than nothing.

Does anyone know where I could find a knee-lifter part No. 93-513 120-91

I attache some pics below.

I temporarly replaced this missing assembly of my lifter with a piece of steel rod but it is not 'aclear' solution... It works very stiff

My local suplier said Pfaff stopped producing this part and I also cannot find any used one...

ps.

Uwe thanks for the manual

regards Brt,

For noncritical out-of-production parts like your Pfaff foot lift roller, I'd recommend make your own, or find/make something functionally equivalent. It's not a high precision or critical part and you're free to make stuff up. You're not running a Pfaff museum, after all.

For example, this roller tip from an edge guide on top of a suitable bolt/shaft/rod is functionally equivalent to your missing part. Of course your parts drawer may look different than mine.

Of course I take into consideration making an 'ersatzteile' of this roller tip. I even found where to buy a kind of wrist joint (photo). There is a plenty of small rollers availiable but I think using this 'fork' may be better because the roll has two fixing points for its axis istead of one on the side. I think this roller has to be strong as the transmitted forces are pretty big. Anw I decided to ask for an genuine part first. Thanks Uwe.

Btw, Did you know that the left slider (cover) of the bed has a small lock - a pin and a spring? I was surprised yesterday discovering it. There is no single word about it in the parts-list (or I missed this). See photos. Finally I also have an used genuine needle bar for replacing :).

Greetings and a Happy New Year for Everyone!

the pin and spring were used to keep the slide plate from coming completely out.  No big deal.  Singer used them as well on the 111W155.

Hi again,

Restoring my 545_h3 'barn' and have two problems:

A) There is a horizontal bar and two levers fixed to this bar with a pair of screw each side (see pic). Two left screws are almost dead so I ordered a new pair. I ordered part no 11-108 225-15 as descibed in the parts list. During the replacement, after unscrewing them it appeared that two left screws are different then two right, however in the parts list all of them have the same part number. (see photo). On the left side I have fine thread (40/inch) diam 5,49mm screws. The right one are normal thread and diam 4,95mm. I believe that the right one are 11-108 225-15 part no but cannot recognize the left one neither in the parts list nor anywhere else in the machine. Can anyone can help me to identify these thick left screws and where I can buy them?

bB) What is No 13-064 383-05 bolt for in 545? (it has a washer and a cotter in H10 version). I cannot recognize its function in the machine?

Regards, Bert

Ha, I'm having a déjà vu experience here. My Pfaff 545 also had mangled screw heads in the clamps on the foot lift linkage bar. I had ordered new screws based on the parts manual numbers (11-108 225-15) but they don't fit my machine either. 

Based on my measurements, I'm voting for the screws in my Pfaff 545 being size 7/32"-40, which is a weird size even in the sewing machine world. I was expecting it to be a 15/64" or 13/64" , which are somewhat common in sewing machines. I had some Juki 1/4"-40 L-11 screws which looked promising, but only for a brief moment. Who knows, maybe Pfaff just found a big box of weird screws on their shelves and decided to just use them somewhere (I really hope I'm wrong here.) 

I found taps for size 7/32"-40 on Amazon so that weird screw size does exist. 

Your best bet for finding screws of that 7/32"-40 size is to look at part lists by manufacturers like Juki, Mitsubishi, etc. that list actual screws sizes. Then order some of those screws and hope for the best. I've not been able to locate any OEM screws with that size. 

Regarding that mystery pin on top of the stitch length mechanism, it's for attaching a return spring. It's only used on the N10 subclass (like on my Pfaff 545), where the stitch length mechanism operates in the opposite direction (there's also no reverse with N10).

I am trying to find these werid screws somewhere in Europe. Maybe UK, so I'll let you know. If not - I am wondering about producing several dozens of them locally. 

And I am happy that the bolt is for H10 subclass only. I was afraid have a some spring missing.  Thanks Uwe.

I will also show you a home-produced roller bar for a knee lifter soon 

Brt,

what about STRIMA in Poland - they seem to have lots of Pfaff parts

Their website does not exist (anymore or not yet) but I bought parts for my Pfaff 345 from them and they were WAY (!!!) cheaper than any other Pfaff dealer I contacted. But not sure if they ship outside Germany.

 

They are listed as Pfaff dealer on the Pfaff website too:

Can anybody help me understanding how the bobbin winder spring should be fixed on the axle? I did a hand-made fix and it's working but I am not sure if it's ok with the original idea. Regards. Brt
