Complete manual: http://www.shopyourway.com/manuals/140735

Look in the manual first, it has ALL the info you need...or have a look at this link:http://www.sewusa.com/Sewing_Machine_Threading_Diagrams.htm

I assume you actually mean the metal ring that holds the small round case that the bobbin itself sits in. There are usually two arms that swing in to hold that larger metal ring in place and then there is a plastic and metal piece that sit behind the large metal ring. fit the plastic piece that may look somewhat like a scoop next to the metal piece that usually has the post the the bobbin fits onto and has a quite sharp tooth on it. The metal ring then goes on to hold those two pieces in place and the two arms swing in to hold the metal ring into place. The bobbin or bobbin case now can be put back in. Hint on metal ring placement: they almost always have a notch that goes at the very top where the arm on the bobbin case sits in when it is in place. You may find it easiest to do this with the machine laying on its back so you don't have to have 4 hands to hold everything in place while putting everything back in.
Good luck!

I just discovered that you can go to www.managemylife.com and under manuals, put in 385.12102 and you can have a free copy of your maual. Hooray, this is a great find because normally you have to pay for it. Happy New Year. Good luck

Welcome to FixYa!

Don't mess with the bobbin! They rarely need adjustment. Sloppy bottom stitches usually come from two things. Tension too loose on the tension dial or improper threading.

Dial tension should be set on about the mid range and you must, must, must, make sure that you have the machine in the proper thread patch. Have someone check it with you. Sometimes a fresh set of eyes will help you spot an area that you missed.

Thanks and if you found my solution helpful, please reward me with a FixYa rating.

I had that problem, too, then realized my needle was in the wrong way. The flat side needs to be inserted AWAY from you.
I have a Kenmore 16528. It was such an easy solution! I was ready to take it in for repairs! Hope that helps!

I'm betting that you put your bobbin in the bobbincase backwards. Hold the bobbincase between your left thumb and forefinger looking inside it. Pull the thread, the bobbin should turn clockwise, if it doesn't flip it over. And also your upper tension could be off and/or your needle isn't in right. Good Luck.
