I was looking to grab a bobbin case spring for my ferdco pro 2000. Oddly enough the manual's diagram shows everything but the spring that pushes against the bobbin when inserted into its casing. As it seems the sucker must have popped out and after a thorough shop investigation, im almost certain my little helpers swept it up before I was able to notice it. I know Johanna has specifically mentioned the bobbin case spring so I know my terminology isnt too far off. I attempted my local dealer and have been playing back and forth for a week. I would just like to order the spring and a few bobbins and move forward. I would be brave to assume that it is the same spring that is used in cowboys and cobras. Could anyone point me to an online reference where I may get the ball rolling? Thank you!

Perhaps the "shuttle spring" would be a better descriptive? Unfortunately I still am not catching it in the parts breakdown.

Not familar with this part you mention. Im not finding it in a consumable parts listing for the 441.  The cobra here was used and to my knowledge didnt have such spring but im always learning. I can say unless it would have a retainer some how it would hit the floor in most all shops and be history.

I looked up the specs for the Super Bull 2000 and it appears to be very similar to the Cowboy and Cobra 441 clones. If so, you could probably try to buy a bobbin case spring for a Juki 441 or clone. It is a coiled spring that is like a beehive: bigger on the bottom and narrower on top. If that internal spring is not sold separately, a replacement shuttle could be purchased from a dealer.

Thank you Wiz. After the first two replies I thought I may be going crazy. Indeed, it looks strikingly similar to say an upper tension spring (conical/beehive). Are there any good online resources for such parts? I'd like to put the order through over the weekend so I dont have to worry about placing phone calls during the week. Very much appreciated.

Looking at Cowboy's parts diagram it is the same breakdown as mine. I take it that the section where it should be is labeled "hook assy" that I would have to grab the whole thing. I dont particularly mind but hearing the bobbin chinging around in the case is both driving me nuts, and making me worried that something is going to awry if I continue to stitch without it.

Have you asked our friendly leather machine dealers if they have a suitable replacement spring?

I would be interested in a part number from any of our dealers, that use these. This is new news to me on the part actually so thanks I appreciate the information. fwiw i didnt see a number in the juki manual either separating the assembly, bummer

My thinking is that the anti-backlash spring is also an ejector spring and is integral to the bobbin housing in a 441 clone. It must be fastened to the bottom of the case and is probably not expected to go missing. If that's how the makers think, they might not offer the spring as a separate item. Hopefully for you guys, I am either wrong or mistaken.
