chrisash Report post Posted October 4, 2018 Hi Just wondered if there are any instructions on how to take the sewing round head apart on the 29 models and put them back together again, my foot feed on a 53 model is not giving the best length of stitch and wondering if i should take it apart and give it a once over or best leave it alone Quote Share this post Link to post Share on other sites
chrisash Report post Posted October 12, 2018 Thought I would bump this up a bit, still looking forinstructions on how to take the head apart on the 29K and reasemble, What order do you go through and any major problems for a rank beginner on this beast Loads seem to have stripped them but no video from what i can see on youtube Quote Share this post Link to post Share on other sites
Constabulary Report post Posted October 12, 2018 I have done this a few times and never needed a video or instruction nor I have written down an order or the like - all parts just fit on one spot - not much you can do wrong and there is nothing that can go out of time. Just start and take some pictures when you have removed a part. Only thing I want to point out is that the pins go out from back to front. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted October 12, 2018 I usually first unthread the machine. Then follow this sequence... Remove the screw above the needle securing screw then pull off the needle clamp assembly from the bottom of the needle bar. Try to drive out the tapered pin holding the take-up barrel to the needle bar. It drives out from the back. Unscrew the four bolts holding the rounded head to the left side of the body. They are on the right side of the head assembly. Two near the top and two near the bottom. If operation #2 was successful, go to #5. If not, go to #7 Carefully pry the round head assembly off the body. Hold the needle bar at the bottom so it doesn't fall to the floor, then pull it completely away from the body and lay it down. Pull out the needle bar for inspection and cleaning. Use Emory cloth to smooth any thread tracks and replace the tiny paddle shaped spring if it is worn or twisted. Reinstall the tiny screws for the paddle spring into the same positions as they came out! This spring is important! If you can't drive out the tapered pin holding the needle bar to the take-up barrel, pull the head away at a suitable down-left angle to let the needle bar smoothly exit as the head is pulled away. Avoid hitting the end of the cylinder arm. The needle bar will be left hanging from the top knuckle joint on the take-up barrel. With the head in hand, unscrew two screws on the bottom that hold the revolving bushing to the inner parts. Remove the butterfly ring and stitch length motion assembly and separate them. Check the hollowed ring for damage, then clean and oil it, or replace if damaged too badly. The part with a puck on the end that rides inside the ring is what wears out. Either buy a replacement part or braze bronze rod over it and taper it with a file. Shape for the best fit with 360 degrees rotation and polish on a buffer. Reassemble, oil and hopefully get 5 stitches per inch at 1/8 inch thickness. Quote Share this post Link to post Share on other sites
