6690 viking sewing machine. Needle not picking up thread from bobbing. How do I fix this problem? I took out bobbin holder and reinstalled. Still not working.
Here is a recent answer of mine on the same question: : Q: Why isn't the Needle Thread picking up the Bobbin Thread? A: Steps to Resolve: Take all of theses these steps before trying to pickup the Bobbin Thread again. 1. Check to be sure the needle is properly installed and threaded. 2. Check if the Bobbin and Bobbin thread is properly installed. 3. Remove any thread tangle or lint from under the needle plate. 4. Remove the Bobbin, Bobbin Case and Hook Assembly. 5. Clean, Oil and Reassemble Hook Assembly and Bobbin Case. 6. Install a new needle according to owner's Manual. Very important. 7. Test for Bobbin Thread Pickup. 8. If problem persists, the machine Timing is likely off. 9. Check Timing: a. Remove Needle Plate (Feed Dog Removal is optional for better view). b. While turning Handwheel (Top of Wheel Toward Operator), observe the Hook. The Tip of Hook should pass behind the Needle shaft, just above Needle Eye, at each upward needle cycle. c. If the Tip of the Hook lags or precedes the Needle on it's upward cycle, that means your machine has slipped out of proper Timing and needs to be Re-Timed. Machine Repair shops usually charge about $90 to Time your machine. With a lot of patience, study and persistence you can time your own machine. Timing a machine is outside of the scope of this reply, but many U-Tube videos will go into great detail of how to Time your machine. Service Manual instructions with diagrams can walk you through it. Timing is very do-able, if you are the slightest bit mechanically inclined, but is still a little tricky the first time (till you find the correct gear, with two set-screws, to adjust). With a little persistence, you should be able to Time your machine. Sincerely, Amender 2019-JAN 06 P.S. If your machine needs Timing, I wrote a post since the one above that goes inot what is needed.
