I need the correct setting for my singer merritt 3140...I keep getting bundling thread from the bobbin

Singer indicates that the 2430 to the Merritt 2404. The Merritt 2404 manual is available on the Singer support site: https://www.singer.com/support . The current link to this manual is https://www.singer.com/sites/default/files/product_manual/9bb8bc029ac33374a16f6ef37fdb37c14c7a8356_0.pdf . To wind the bobbin, make sure that the needle is up and lift the presser foot. Hold the hand wheel with one hand and keep it from moving. With the other hand, loosen the knob in the center of the hand wheel by turning the knob towards you. If the thread is not already on the spool pin, place it on the spool pin with the thread retaining slit to the right. Put the spool holder on the spool pin so that it holds the spool firmly.

Next snap the thread through the thread guide post and open the top cover. (If you have been sewing with the spool, unthread the upper thread back to the guide post.) Wrap the thread the bobbin tension disc going clockwise as you look at the top of the disc. (Bring the thread in front of the machine as you move to the left; then bring around to the back as you bring it to the bobbin winder.) Bring the thread up through the hole in the bobbin. Place the bobbin on the spindle with the hole up. Move the bobbin winder to the right. Hold onto the thread above the bobbin while you start winding the bobbin. After a few turns are on the bobbin, you can let go. After the bobbin is full (or full enough for your task), clip the thread and remove the bobbin. Move the bobbin winder to the left. Tighten the knob in the hand wheel by turning it away from you while holding the hand wheel.

I hope this helps.

I found a free instruction manual for the 1872. I can email you a copy.
Let me know!

Get some scrap of the fabric you'll use.

Remember this phrase. Loops on bottom top tension too loose. Loops on top... top tension too tight. (or bobbin tension too loose)

In your case you need to loosen the top tension until you start to see loops on the bottom... then tighten it slightly.


Here's a manual for future reference

First check that the needle isn't bent. (The simplest thing is to try a new needle.) Next check that you have a correctly wound and installed bobbin. The hole should be facing up and the bobbin thread comes off the bobbin to the left. Make sure that you threaded the bobbin correctly (notch A at the center and then to slot B to the left. (About 7 if you have the center front of the bobbin area at 6 on an analog 12-hour clock.) Pull the thread diagonally across the bobbin and then close the faceplate with the thread going through the opening of the slideplate. Hold onto the top thread while trying to bring up the bobbin thread.

If the bobbin thread still will not come up, remove the bobbin and clean the bobbin case. You may want to clean under the case as well, see page 81 of the manual. This is page 83 of the PDF: http://www.singerco.com/uploads/download/652_288-974-972-244-2405-588-875-1195-3130-3140.pdf .) Do all of the oiling of your machine while you do this maintenance if you haven't done it in a while.

The bobbin case has several parts that combine to provide good bobbin thread behavior. First there is a tension set screw that keeps the bobbin thread at the desired tension. If it is too loose or too tight the thread can't be pulled from the bobbin. (It's easy to strip the threads of the case, so be very careful.)

This is easiest to check on other types of sewing machines with a vertical bobbin case. For those, you remove the bobbin case and thread the bobbin through it correctly. Dangle the bobbin case from the thread (carefully). The bobbin case shouldn't slide on the thread but you should be able to pull out more thread if you hold the center of the bobbin and bobbin case. (Hold gently so that the bobbin turns.)

Next the bobbin race and hook need to grab the bobbin thread and twist it with the top thread. If these are damaged (perhaps by a bent needle), they won't work properly. These are at the back of the bobbin case.

Try replacing the bobbin case or parts of the bobbin case as needed. The Singer 947 is in the same line as the 244 and should use those parts. http://parts.singerco.com/CPpartCharts/2_2999/240_SERIES.pdf has the parts list. Try contacting a Singer dealer to get the parts. Unfortunately, my usual vendors only seem to list the manual as an available part for this line.

I hope this helps.

what size bobbin and do you have pictures to show how to thread 9608 singer machine

With some machines you need to have the thread on the bobbin running counterclockwise.

http://www.singerco.com/resources/threading.html Check out the threading diagrams on Singer's website.

Run the thread around the little silver knob on the top of the machine to the bobbin threader on the top right. Wrap the thread clockwise around the bobbin a few times and then pull the bobbin threader toward the silver bar. If you put your hand on the crank wheel, you will feel a place for your finger to set. Push there and the center of the crank wheel will sideways allowing you to thread the bobbin when you press the pedal. I'm sure my terminology doesn't make any sense.

If you lift up the thread holder, the bobbin holder is inside. Loosen the hand guide to stop the needle from going up and down. Pull the thread around the top thread guide and back into the bobbin holder. Thread the bobbin and move the bobbin over so the guage is "inside" the bobbin. As for the manual, the Singer Merritt 2404 is applicable to the 2430 if that helps.

Go www.singer.com they have the manual for this machine available for download on their machine.
