I don´t think the shaft is stainless steel.

I haven´t pulled a top shaft yet and cannot support here but you at least have to remove all gears and all parts attached to the top shaft. I have a disassembling / assembling instruction for the Pfaff 145  - maybe it helps you a bit - the head is "quite" similar.

I have sent you the parts lists I have - I hope they help a bit.

Thanks for that Constab.

At the moment, I am having a think about what to do...

Hopefully after Christmas, after stuffing my face with beer and Kloeser, I will have a clearer idea of how to proceed.

Hope you all have a wonderful Christmas.

Alex

Ye Gods, Thats some serious damage. It must have received  one almighty ' wallop '  to snap the shaft. 

 I thinks its safe  to say that everyone on here is feeling your hurt .

Well, if it was mine I'd be considering three options 

  • A total rebuild/ restoration 
  • Replace just the shaft
  • and/or  obtaining a donor machine 

I think the third option maybe good idea if you wish to speed things up to get into making shoes ? 

Whatever you decide to do, I wish you the best ,

Man I was dizzy reading this pdf without pictures.:wacko: I need pictures!  But have a 145 I need to clean and tune soon.  My sister bought it sight unseen by me at an estate sale only because I needed a Pfaff knee lifter table for my 238.  Didn't even pay attention to the machine for a couple of years. But then realized is was a pretty nice 145.

don´t know who typed it - must be decades old. I once found it in a lot of manuals I bought. You may need the "old" parts list (with old Pfaff parts numbers) to understand what parts they mean. I have an old 145 parts list but its too big to attach - if you need it send me a PM so I can forward it by Email.

I have been thinking...  I have several possible solutions at the moment, but I think I have a quick and dirty one that might work...temporarily

Step 1: I will leave the shaft in the sewing machine and drill a hole through the length of the small broken off part. ( I will find someone with a lathe).

Step 2  This part will then be glued with JB Weld to the main part of the shaft and will act as a drilling guide to allow me to drill 15mm in to the main shaft, by hand or with a drill press.

Step 3: Thread(left hand) the hole and then ream out the hole so that the only threaded place is in the main shaft.

Step 4: Use a reverse thread hex head screw to fix the two pieces firmly together...I might have to re-glue the two pieces since it will have been exposed to high temperature during the hand drilling

 

Might work... Just depends if the shaft is terribly hard...

Cheers

good luck with that!  :blink: I know you want to avoid pulling the top shaft. But I´m not sure if it really is worth the effort and at he end not sure if it will work / last at all. :wacko:

If it were my machine, I would take it to reputable cast iron welding shop and get their opinion and estimate for repair (with the shaft out).  Regarding removing the top shaft, I can only say it wasn't that big of a deal with my Claes 8345 patcher.  Removing the taper pin holding the handwheel onto the shaft was the big deal, I couldn't decide which way the pin went because of my inexperience (the ends were somewhat deformed) and lack of instructions.  In your case, if there is a taper pin,  it may be in the handwheel and off of the machine, in which case removing the shaft should be straight forward.

Iirc once my machine was reassembled, I realized the shaft could be removed without totally stripping the machine.  Perhaps the professionals will comment on that for the Pfaff 193

Btw, when you go to remove or replace a handwheel, don't beat it on or off the shaft, lock the internal gears with a block of wood or similar and rotate the handwheel while pulling or pushing.  Be sure the shaft and insides of the handwheel are free of burrs, smooth (a micrometer helps) and lubricated.

Regarding your doubt about the hardness of the 193 shaft, fwiw, I needed to true-up the end of my Singer 45K25 shaft recently to re-install the handwheel,  it filed/sanded easily, so it wasn't too hard.

Best of luck with it.

The alignment would have to be very precise . 

All the best, and let us know how it turns out eh ?
