Pfaff 193 arm shaft disaster..

[alexitbe]

Well, I have been trying to get a post bed roll foot for shoemaking for ages and just before Christmas I found one.  Instead of the 9hr journey each way, I convinced the guy to send it buy post...  It arrived just in time for Christmas and its broken... Seriously broken.

The arm drive shaft has been broken right at the balance wheel.

So I have two question one about disassmbling and the other about fixing the shaft.

Is it possible to loosen everything attached to the arm shaft and slide it out or will I have to disassemble the whole machine? I don't think I can do the latter..

Should I replace the shaft or would it be possible to bronze braze it?  I have an old pfaff 142 and wondered if the arm shaft might fit... I cannot find anyone selling spare parts for the 193 despite thinking it was still in production...

Its really put a dampner on my Christmas, I know it shouldn't but I thought I finally had the last important piece for my shoemaking hobby... and now I am back to fixing instead of shoemaking..

 

Any advice and word of hope would be greatfully recieved..

Have a good Christmas.

Alex

Damn - thats bullshit!

Shipping a sewing machine from an "unexperienced" seller (in terms of shipping) is a 50/50 risk . I would always remove the hand wheel form the machine when shipping it or support the machine with styrofoam the way the hand wheel is free. And you at least need 1.5" styrofoam on each side (more is better) of the machine + it has to be packed real tight!

I have a parts list for a "new and old" 193. I´ll send them by email.

Pfaff once changed their parts numbers - what I have observed is that the old part number is part of the new part number meaning they added some digits as prefix and some digits as suffix.

The old number of the arm shaft is 10002 - the new number is 91-0100 002-05

College Sewing seems to have the shaft - seems this is the one but better check with them:

German dealers might be cheaper but my experience is (ordered Pfaff parts once and requested prices from 10-12 different dealers) that CS necessarily is NOT the most expensive. Prices from German dealers varied by more than 100%.

¿¿Looks like someone filled in that spoked handwheel for heavier mass??

And Merry Christmas.

Thanks Constab and Jimi for the information...

It was really my fault, the old man didn't really want to post, but I convinced him it would be ok.  So I must take the hit...  Lesson learned.

The machine was from an old Salamander shoe factory, so maybe they filled in the wheel... The machine hasn't been used for a very long time and the old man said he was glad it would be used for shoemaking again.  I guess he used to work in the factory.

 

Will I need to strip the sewing machine completely? This is my biggest fear.

Cheers

Really strange, that a shaft of stainless steel can fracture like that

You could use the tactic some of my old customers used, something like a letter / email to Singer stating my machine broke after only 100 years so i demand a replacement, although in my case it was workwear that had not lasted being used for three years or something like the red uniform is to red even though they had photo's before they ordered it

LOL

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.

The visible crystal structure is not from stainless steel.  I also don't see why a manufacturer would use more expensive SS when CS will do the job quite adequately.

I guess you are right - but still weird. The package must have taken severe beating.

Bent shafts and broken hand-wheels are common when sewing machines are not properly supported and packed.  Many items get dropped a few feet during shipment for one reason or another.  Insurance might help, but sometimes very hard to get the parts to repair or to straighten a bent shaft.  There are stories here too about cracked or broken beds.  The lesson here is to ensure the shipper knows how to pack and packs it correctly.  Otherwise, may be best to skip the "great deal" and wait for one closer to home.
