yes!

I have this motor mount for quite a while and I wanted to junk it but figured it could be a mount for a speed reducer. Shaft is 15mm. Holes on the mount are 16mm but I found a thin wall 16x15 tube in the scrap box. Works for me. Step pulley is from another machine and just put on for testing. Motor mounts for sure differ. Just as and idea...

I meant the bits on the 2nd pictures.

The serial number is the key for figuring the date, maybe this helps: https://ismacs.net/pfaff/pfaff_manufacture_dates.html Some of the parts do not belong to your machine obviously.

first picture looks like a Singer 45w of some kind - whats stamped on the oval silver tag? EDIT: Maybe 45w53 or similar - just look up some other sub classes maybe you find the right one https://www.manualslib.com/manual/154111/Singer-45w53.html?page=4#manual EDIT II: https://www.manualslib.com/manual/364556/Singer-45w.html?page=2#manual

Just replied your PM and just saw you post here. Yes, the curved spring is putting a little bit pressure on the bevel edge of the washer - so your problem then is the missing spring

its a super fast clutch motor - you will not have fun with it - get rid of it - buy a servo Singer 211G and 211U had similar dipsticks - maybe worth checking parts lists. I think Singer called them oil gauge.

Your gearbox is set up correctly . But I´m not sure if there isn't missing a screw that hold the pinion on the shuttle driver - or is the screw head sheared off or is it just covered with dirt? See picture below. Sometimes when people take apart Singer 29K or Adler 30 patchers they put on the cam pulley the wrong way meaning rotated by 180°. When the cam is rotated by 180° you will never get the timing right. But I only can guess here cause I´m not in front of your machine.

have you adjusted the cam? See red arrow in my picture.

w/o knowing your machine and w/o knowing what in particular you did or have tried so far or what YT video you have watched... there is a cam with a wing nut on the rear, when you loosen the wing nut and shove it in the upper position an tighten it again you get more foot lift. If it does not help loosen the two screws in one of the reed circles (dose not matter which) then rotate the hand wheel until the inner foot and the needle tip arrive at the throat plate level at the same time then tighten the screws. hope this helps.

Head mounted on a base plate so I can switch the head with my 29K71 patcher which has the same base plate mounted so one stand for 2 machines. https://leatherworker.net/forum/topic/79339-singer-108w20-my-new-binder-setup/ My Singer 51w Post bed machine setup which also is used with 107w & 143w flat bed machine (switch head and drive belt - and ready to go) https://leatherworker.net/forum/topic/89568-singer-51w-post-bed-143w-107w-flat-bed-setup-on-cut-down-singer-stand/

maybe safety clutch triggered - if it has one.

DOT, CS Osborne or Stimpson with brass "core" DOT also has a PULL THE DOT line which is much stronger that the plain ring snaps nut not very fashionable so depends on the purpose.

Maybe try a Teflon foot or roller foot (both dirt cheap). You seem to sew the material "unguided" (no hands on the material) have you tried "spreading the light fabric with thumb and fingers a little bit?

But it will not fit your 239! The 239 have lot in common with Singer 111 but NOT the needle plates and feed dogs! If you are able to cancel the purchase better do - it will not fit!

Inline foot set your needle plate cut out is short enough so the outer (now rear) foot can rest on it. I had to order a new needle plate + feed dog for my 111G156. MIne is on the way: https://www.ebay.de/itm/154704899719

or maybe a an "inline foot set" but not sure if that works on your 239. You may need a needle plate with a shorter cut out then cut off toe so the (former) outer foot can step on the needle plate right behind the inner foot. Know what I mean?

Looks like an quite early black machine with paint quite worn off. I´m not sure but maybe at that time there was no H1-H4 rating. Bobbin are usually all the same in the 14x class (approx 22mmx11mm). Needles depend on how the machine is set up you can set it up for different needle system by raising and lowering the needle bar. Not a big deal really. Keep in mind - what you see on the tag is how the machine left the factory decades ago and it is well possible the machine has been altered / set up for different purposes several times (old machine) during its lifespan. Best way to figure its specs is testing it. Old / worn machines are always a gamble.

I do non´t think you will find a 100% matching paint of the shelf. I´d check home depot (or similar) and buy some brown rattle cans. But if this is of major importance for you and you really want it very close I´d check with a paint matching service or your local car painter, they may be able to find the closest shade for you. You may have something like this locally: https://www.myperfectcolor.com/Custom-Color-Matching-Services/33936.htm or try a color detecting App for your phone (the one with out wires ) like Color Grab https://play.google.com/store/apps/details?id=com.loomatix.colorgrab&hl=de&gl=US

roller foot is not possible on tripe feed machines. You need a drop feed or needle feed machine for that.

I don´t know the answer but I can guess. Knowing similar machines have a bobbin case opener on the hook - maybe the 3bl has no bobbin case opener. You will notice when you look on the underside of the machine. This is just a wild guess!!!

That basically it is a Adler Class 4 machine only Dürkopp labeled (Dürkoppp and Adler merged in 1990). Pre 1930 manufactured I think. Needle system is 328.

sorry - I was on the wrong track with my SV machines statement I had the thread with the 133K darning machine in mind Looking forward to what the Singer museum will say...

I only can imagine a "hole puncher" - but don´t ask me for what purpose. I really have no clue. Is there a drive shaft for mounting the hook?

That indeed is interesting.... Well its an SV machine - very little to nothing is known about certain SV models, some are predecessors of later standard machines and some are kinda prototype or made for a special customer application.... no one really knows em all. Maybe yours had tension units positioned somewhere else. Right - no slot for the take up lever - very odd. Can you post a picture of what is behind the face plate please. EDIT: Just a guess - no hook, no tension units, no take up lever - was this machine for what ever reason meant for just punching holes into... what ever????
