This is a special 335 subclass. According to the model plate, #335-H3-734/01-6/01-921/01-BS -H3 means regular maximum lift of 11mm - 6/01 should be the standard model as to the feed dog and feet. -B means a B subclass which is on the lighter side of what it can sew plus a smaller balance wheel. C and D class are heavier and a larger balance wheel -S means for sewing cloth -734/01 not sure on this designation but the extra little lever to the left of the stitch length lever I think allows you to change the upper feed in relation to the lower feed dog -921/01 again, not sure on this designation Like Constabulary said, I would remove the stitch length lever and the back plate, then replace the lever and wee what you got. The stitch should be longer then That lever comes out with a set screw. You need a long screw driver coming up from the bottom to retighten the set screw. Generic stitch length plates can be ordered to replace the existing one and they are not real expensive here in the States. Australia, maybe. glenn

Bradford, Both of these machines are good machines. Bob at Toledo (Cowboy) and Steve at Cobra are both great to deal with. To me, the deciding factor would be which one is closer to you as to shipping costs. glenn

We need to see a pic of the stitch lever and plate behind it. Pfaff 335 machines have had maximum stitch lengths from 3mm to 6mm depending on when they were made and the sub class. The ones produce today have a maximum stitch length of 6mm. glenn

c, Not all parts were changed, just some. I do not think you can get any of the metric parts today. I have yet to find a source. glenn

AngieNZ, The 29U173A was built in Japan. Some of the parts or slightly different in spec sizes compared to the parts for a Singer 29K73 and 29K173. They went to metric sizing on some items and they are definitely different. glenn

C, Singer introduced the cam adjustment screw for the shuttle on the 29K51 series which I think came out in 1923. Up till then, all the 29-1thru 5 and the early 29k1-33 only had the long drive rack on the bottom with no adjustment. Glenn

Send pics so we can see what she looks like! glenn

There are machines with feet for ruffling. A lot of time machines will have a differential feed in that the upper feed and lower feed can be changed so that they are not the same. The Singer 144W304 comes to mind. You can change the amount of difference in the upper and lower feed. glenn

Eddieb, They do make pedals for stand up operations. What motor you choose will help determine a stand up pedal. Where are you located? This will also help to recommend a dealer or place to purchase the servo motor. glenn

Please us the foot from the side and front as well so we can help identify it. glenn

You can but it also requires a different take up lever and some other adjustments. Not a quick change. glenn

I have seen a few of the factory electrified machines. This one has a slightly different motor however with a different clutch on it. Any Singer number or identification on the motor? The table does not have the cast extension piece on the back that Singer came up with to mount the motor. I would say it is not a factory issued set up. However, still could be a Singer motor. I would like to see more pics of the motor. It has the hub and shaft for a front mount wheel which I would change the balance wheel to. Part of the take up adjustment is missing. glenn

Man, that looks nice! Great job on the table. Might consider making them to sell? glenn

Nuttish, I am not seeing a bobbin case opener in the picture. It may be there but I do not see it in the picture. Give us a few more pics of the bobbin case area without the flip down guide. glenn

jshep, You want to use 3L v-belts. The length of the belt you will have to determine from machine to motor. 3l belts fit the pulleys on sewing machines very well. You can get them from Sewing Machine Dealers or from Automotive stores. once you know the size, i.e. 38" or 39" etc. glenn

Sends us some pictures once you have the original parts back in. Make sure they are close ups. This will tell us a lot and then we can make specific suggestions to you and how to fix it. glenn

Send pics of what you have once the original parts are back in. We can suggest things but pics will tell us a lot! glenn

It looks like you missed the thread into the take up spring but that will not effect the needle picking up the bobbin thread. The safety clutch might have gone out. It is the silver button on the base part of the arm which is on the right side. Take out bobbin and unthread needle. Press button down and turn balance wheel towards you until your hear a click.. If you hear the click, safety clutch has reengaged. If not, it probably was not the safety clutch. That leaves timing and a trip back to the dealer. glenn

C, To my knowledge, the only short arm that Singer ever made with the large hook was the 29U171 which was made in Japan in the late 70's. It looked a little different than any other Singer shoepatcher. I have an original brochure on the machine. glenn

C, The side wheel was on some of the subclass up to the 29k51-56. After that, the front wheel mount was an extra charge, not standard. Machines might have the front bub, but not the shaft and gear. The 29K70 came out after the 29k58,60 and 62 series. It came out only on its own. Don't know why. It was replaced by the 29K71 which was part of the 29K72 and 29K73 which was a series . very few parts changed in that series compared to the 58,60,62 series. glenn

Jerseyfirefighter, Used hydraulic clickers usually start at about $3000.00 and up. Their is someone in New Jersey that sells used machines. I will try to find their info and get it to you. glenn

Proleptic is the publisher of Shop Talk. They are in Ashville, NC. Ask for Dan Preston who owns it. glenn

-H-3 means 11mm lift, H4 would be the high lift version at 14mm L- leather machine C- class. the D lass is the heaviest and has the largest diameter balance wheel P- means 4 motion drop feed N- means maximum 6 mm stitch length as does the 6 in the model number M- safety clutch not sure on the 1A glenn
