20 Most Recent Kenmore Drop-In Bobbin 505S-21BH Mechanical Sewing Machine Questions & Answers


Usually, it is the top thread causing the problem. Rethread entire machine. Then, pull both threads (upper and lower) with the presser foot up and leave a 6" tail. Make sure that you do not miss any guides, check your manual to make sure that you haven't missed a guide in your threading, and the direction of your thread on both bobbin and upper going the right way Youtube has excellent videos on threading for free..

Most likely the internal lubricants have "seized" or evaporated. Time to take it to a good mechanic and have a proper professional COA (clean/oil/adjust), which would be about $50-75 around here for a mechanical machine.
Not using a machine is one of the faster ways to "kill it". Run sewing machines with the needle out, at top speed, for at least 5 minutes a month if you haven't sewn with them that month. They'll be practically immortal that way...

There's a website called managemyhome.com which is sponsored by Sears. It's free to join. Go to the Home Manager column and choose Owner's Manuals from the drop down menu.

You can type in the brand name (Kenmore) and model number of your machine. Not all of them are in there but, I did find the one for the 1950280 question. It's a pdf file.

For the 38516764 question, please double check your model number. I received either no response or a Kenmore Elite dishwasher manual in response to my query.

This sounds less like timing, and more like a threading issue.
Make sure the thread is properly in the tension disks in the top of your machine.
