Pfaff 335-17B S Journey To The Unknown!

[Trox]

Hey Tor, just checked again, the thread is nº12-24 unc i think. you can see the difference between the metric one. i am still trying to find the nut that was broken with the balance wheel in the picture.(its glued together)

Yes, it might be because its made before they changed to the new metric standard. There is a small hole over the big one for the takeup spring. There should be a pin in there that push on the mechanism behind your new unit; when you lift the presser foot. That again pushes the disks apart and release the top thread. You see this long pin # 91- 013 091-05. Here is a page of the new type, look for the same in the old manual.

Hi Everyone, thanks for the response.Here is another cheap option. it is a nakajima 280L tension unit which costs the grand sum of $9.87!! can you see any resemblance to the 335 one? i know it looks more like the singer tension unit but i think it is still a great option. it dosent have the small wheel and the bent bracket where the thread goes through, but anyway? the small screw that holds it on to the machine was missing but the two screws that hold the spring on the back fit!! by the way how does that release work for the disks, because it looks like there is a hole for the pin but there dosent seem to be anything behind there?? here are some more shots..

There also is a small curved metal piece where the thread take up spring rests on - it is missing at your machine.

yes that small curved plate is possibly to stop the spring from going back around the other way?? in the casting where the tension spring goes it has a step and that seems to be doing the same thing-stopping the spring going back around?? thanks for the parts page tor, i cant find any old manuals for this one. just a few pages of feet, needle plates and binders and stuff(335 H3 subclass parts) . looks like this one has no parts to open the disks although the hole is there in the casting for the pin to protrude out?? "it was probably still in the think tank" i will maybe stick something in there and see what can be done?? thanks for the help guys.

Thanks trox, in the end i had the newer parts manual downloaded. i tried writing to pfaff a couple of months ago but no reply. i have just sent another email, so lets see if they reply this time. the hinge is on and the machine is hooked up to my patcher treadle, so will put some more pictures up soon! almost there!

[jimi]

Now this journey has been explored and is known??? we are almost finished. thanks everybody for your help and comments!

Hi Jimi,

You did a great job and worked very fast. The only thing remaining is buffing up the needle plate to a high shine on your Buffing wheel. I do that to all my plates so the leather will feed better.

Hi Tor, maybe it dosent look like it has been done but it has been brushed with the brush in the drill, although you are probably referring to the cloth wheel and jewlers rouge maybe?? looks like it still has its original marks when it was machined.

[Trox]

Hi Jimi, yes something like that. However, with a modern buffing compound not jeweler rouge ( thats for jewelers, use something for steel) I have the felt wheel on a bench grinder for that kinds of jobs and a German aggressive polishing compound. Keeps the steel free of rust and feed the leather much better.

Here is the update on the machine. now it has a new 1Hp servo motor fitted to a "mean time" table and some new decals on, new swing down guide drilled and fitted and some new feet and binder plate. thanks again to tor,contstabulary and other LW followers for their help and comments. just to say, dont think that it is impossible to get that chunk of metal going again. some of them just need that clean up and oil part that was left out and a little bit of your time.
