Google is your friend (sometimes) here is a download link for the manual: https://ismacs.net/singer_sewing_machine_company/industrial-manuals/17-22&17-23-manual.pdf Pictures will help to visualize your machine issues.

The predecessor is the Singer 107w50. I think it shares a lot of parts with this machine. Yours just has a more modern casting. I think it is late 1950´s -1960´s made. The predecessor flat bed version of your machine is the 107w1, 107w2, 107w3 and the like. The flat bed machines for sure share some parts with the cylinder arm version a s well. I´m almost certain that the instructions for the 107w50 will help you a lot with your machine. https://www.manualslib.com/manual/364298/Singer-107w50.html?page=6#manual

hope they did not turn out too small

I have these Mil. Spec. pattern files. Do not recall where they came from - not sure if they help you. I have more but cannot upload them - files are too big

do you have a picture from the left side / the face plate so we can see if parts of the tension unit are missing.

do you need just the hook or the hook + hook saddle? If just the hook I probably have an idea but you have to remove the hook from the saddle first so that I can see the bottom side.

Don´t know where you come from but I restored my 29K71 with parts from College Sewing and they were all fine except the shaft for the front drive (no drilled pin hole). But bit by bit I replaced all non OEM parts with OEM Singer parts but thats a different story. The encircled thingy IMO is parts of the darning device.

Wiz, the 34K11 subclass it the much heavier subclass in the 34K range. The upper arm and hand wheel are from the 45K and it has a larger hook than the other 34K's (like 34K5 or 34K1 or the like). It is using the 214x2 / 328 needles.

Very similar to Singer 96K.

When you want to pick up the bottom thread you have to hold the top thread with your fingers. Send me a PM with your email address so I can forward you a manual for the 34K11 - file is too big to attach here. I think 12mm is pretty much the max. you are able to sew with either of the machines so keep in mind that with 12mm material thickness you run them at their very limit! Not sure if the 34K11 will be good at this at all with it´s rather narrow feed dog.

I agree and most likely a touch up could make it look even worse cause you will most likely not find a 100% matching paint and the original paint is already a bit aged so that makes it even harder to match...

Some pictures of the machine would help so we know how it is set up. But usually yes. Roller foots are fairly cheap an on this machine class they just mount where the regular presser foot is mounted. Depending on the roller size you probably have to adjust the foot bar height. https://www.ebay.com/itm/165207112611

You cannot retrofit a walking foot to sewing machines. There are "top feed" attachments for certain domestic machines but that is not even close to what is considered as a walking foot (aka triple feed = bottom feed + top feed + needle feed) in the leather trade. The 17-30 is a light - medium duty cylinder arm machine with drop feed and reverse. Some may have a roller foot some may have a straight presser foot. They have a long beak shuttle with fairly small bobbins.

I do not agree that the 34 subclass is the "heavy subclass" - see above list of sub classes. The 34 is the same as the 30 but with motor stand. The motor stand makes it a 34 everything else is like the 30 incl. needle System 88 - the head only w/o treadle or motor stand is the 30. Check the list. IMO the heavier class has the higher foot lift as well, meaning the machine that takes the 214 needles should have a 15mm foot lift. Thats at least how I understand the subclass list. But I`m maybe wrong. How high is the foot lift on your machine?

They are expensive indeed! 29K shuttles are not compatible with CLAES. CLAES pathcers are the most excellent patchers (high lift, long stitch length...) nothing better out there. But when it comes to spare parts I would always go with the later Singer 29K models like 29K71 / 72 / 73 cause their parts are still made and affordable. Made in China or Taiwan but still! But well depends on what one needs or expects from a patcher. The later 29K´s are technically more advanced than the earlier model and quite capable when properly set up.

alright - checked the parts list and looks like the 328 / 214 was the needle for the 40, 43 & 44 subclass. So if yours is a 34 (mistyped?) then it takes System 88 and if it is a 43 then it takes the 328 / 214 needle. Confused?

Just checked again looks like they had a 8245 with 328 / 214 needles also. So it is well possible that your machine (subclass 43) takes 328 / 214 needles. BUT the 328 needle system is special cause different needle sizes have different needle shank diameters. Personally I never have seen a 8345 with 328 needles. A rare machine and I know someone who wants one - right. Glenn?

I think the Mod. 200 came in a subclass for 328 / 214 needles. Here is a list of sub classes for the 8345:

The only needle that could probably fit is the 332LG (this is the longer version of the 332 / 29x3). 332LG and System 88 have the same length BUT the 332LG has a slightly larger needle shank diameter than the System 88. So maybe they fit - maybe not. But to be honest I guess they wont but depends on the needle hole in the needle bar.

Well, the Singer Manufacturing Co. we know for industrial sewing machines is no longer producing industrial sewing machines and no longer exists. They stopped loooooong time ago, several decades ago I´d say. Basically someone has bought the brand name Singer and they are now marketing sewing machines but they no longer manufacture industrial sewing machines in their own plants and The domestics machines are for sure made somewhere in Asia. Singer nowadays is just a brand name among others. The head company is SVP they own the name Singer, Husqvarna / Viking and Pfaff. When it comes to industrial sewing machines don´t expect anything from them, they are just marketing "domestic or consumer" sewing machines but no serious industrial sewing machines (or do they?). All to my best knowledge.

just came to my mind - maybe the safety clutch has tripped or one of the timing belt pulleys is loose / loose set screws or the timing belt is a few teeth off.

This is where you have the slider (far to the right) This is where you want the slider (far to the left) - the further left the slider is the higher the foot lift. For moving the slider you have to loosen the wing nut or in your case the small lever on the slider.

I would guess this rather is a hook timing problem but hard to tell from the distance.

Move this slider to the left that in crease the foot lift. The further left the higher the foot lift. If that does nor help pleas post pictures of where the presses foot is mounted.
