then the feed eccentric is out 180 degrees. You have pic of the machine? glenn

Have Constabulary send you copy of the manual. Bobbin winder looks complete. glenn

Maybe Not hooked to a servo motor correct.? glenn

Put the shuttle carrier shaft in the bushing and see if it wiggles. Is so bushing is worn and needs replacing. bushing are pressed in. My late father came up with a way to remove the bushing a with a nut, bolt and big washer. can remove old one and replace with new one with those 3 items. The shuttle carrier should just turn in the new bushing with out any wobble. To take the long drive rack out, there is a connecting screw in an access hole in the back. Screw #89. That release the long wrack. I normally have to pull the replaceable horn to replace the drive rack, The teeth on your drive rack look go. Chances are wear is in the drive pinion and the following pinion. I will also tell you the bell crank is probably worn as well. To replace that you have to take the end of the head off. 4 screws hold it on. You also have to drive the piston pin that connects to the needlebar out. It is a tapered pin that drives out from back to front. glenn

Dremel the corners very light with a sanding disc. Dremel the corners very lightly with a sanding drum.; glenn

yes the gap on the spring to the bobbin case. spring should fit tighter. glenn

If still sewing backwards, the feed eccentric has to be 180 degrees out of adjustment. safety clutch out? glenn

Loosen the lock screw on the spring and see if you can tighten the regular screw on the spring to increase the tension. Spring is up and seems to be catching on the thread. glenn

Derust, clean, oil and see what you got.. she is an old girl. Missing cover plates. Alasdair got any threading info? glenn

clean the machine up first and oil it good to see how it turns,\. Glenn

Push the lever down for reverse. glenn

I have new levers C. glenn

The 29K31 is a big bobbin long arm shoepatcher. Your part number is wrong. Singer did not make a 82202. They made a 82020 needle plate for the big bobbin. I have 82020 plates. Original Simanco plates unused or New old stock. Price is $55.00 plus shipping. I do not have that many. It is compatible with the 29K30 and 31 machines as well as later big bobbin Singers. Let me know if you want it. glenn

Send me pics of your bobbin winder please Amy. Lets see if you are missing anything. glenn

Gears and rack are worn. Too much play in those areas from your video of the shuttle carrier. With no wear, the shuttle carrier should hardly move when you turn it by hand. You look at the drive pinion, following pinion, short rack and long rack for wear. Also check the bushing that the shuttle carrier shaft goes thru. You might have to replace all of those as well as the bellcrank. I have rebuilt shoepatchers for over 45 years so I know what areas to look at. glenn

You can sew #138 on a Pfaff 335 but you must enlarge the hole in the feed dog and inner foot to accommodate the #138 thread. I also just touch the the corners of the space bar on the the machine. That is where the gap on the bobbin case is that the thread passes by the each stitch. 335 Pfaff do not have a bobbin case opener since they are a horizontal hook machine. glenn

P means 4 motion drop feed. H4 is high lift. Probably using needle system #190 Nice machine glenn

I have a manual written by Singer for the complete 29K70 shoepatcher. Will try to find it. glenn

ok Your thread controller disc is off. It is just below the tension. Loosen the black screw and make sure it is in the center of the slot. Unwind the tension nut and take the beehive spring out Stretch the spring out grabbing each end of the spring. That will increase the tension in the spring when you put it back on and tighten it. By hand, turn the balance wheel and let us watch the hook pick up the top thread from the needle and let it come out the feed dog. Video needed of this. This will tell us if the bobbin case opener is set correctly. We can then tell you what we noticed is wrong. glenn

Stitch length lever set at zero? pics please of machine glenn

Constabulary stated earlier it was screw #544383 which is supposed to be the same as #237. Specs 9/64" x 40tpi. I would have bet it was metric since Singer changed a lot of parts and screws on the 29U series which was made in Japan not Kilbowie where all of the 29 machines were made after 1923. glenn
