Janome Gem 760 sewing machine: needle hits bobbin casing

Have installed a new needle in its correct position, but it keeps hitting the back edge of the bobbin case. I have cleaned the machine, it is well oiled, I am just stumped. Can anyone tell me what to look for and if this is something I can fix myself? Could it be as simple as buying a new bobbin case? What could go wrong with one? Thanks for any tips.

From what I've read that you've put down it sounds like the machine is out of time, which means it needs to be fixed at a sewing machine repair shop

SOURCE: will not pick up bobbin thread

Unusual for this machine. Check to be sure the needle is inserted with the flat side to the back of the machine. If it is, remove the needle plate, bobbin and bobbin case. Turn the hand wheel slowly toward you and see if the point of the hook is above or below the eye of the needle when the hook point is aligned behind the needle. If the eye is above the point of the hook the machine is out of time and best taken to qualified technician.

SOURCE: I just bought a janome mini sewing machine. I

First, in order to get the bobbin thread up, you have to turn the wheel backward, not forward. If you try this, and it is not the problem, keep going.

Next you need to check the needle. There is a screw on the right side of the needle carriage right underneath the underside of the top...unscrew this and the needle should come right out. The flat side of the needle shank should go towards the back of the machine. If it isn't, switch it so that it is and try again.

If this doesn't solve your problem, what has happened is that the gears in the machine have gotten out of alignment. There is an easy fix:

Take off the plate that covers the bobbin chase...there are two screws one on each side. Remove these...you need a stub screwdriver, because regular ones will not fit under there.

Remove the bobbin carriage and the bobbin, making careful note of how they fit back in. Take a picture before disassembling it so you have a reference.

The part that carries the thread around the bobbin is still in the machine. Turn the wheel and you will see it rotate. What has happened is that the needle is not going down in the machine at the right point because someone kept sewing after it jammed and one gear kept going while the other one didn't and now it is out of alignment. These machines have plastic gears and the can slip past each other if you aren't careful not to stop immediately when they jam.

To fix it, you are going to have to do some trial and error. Grab the rotating part of the bobbin chase and hold it firmly. Rotate the wheel forward until you hear it click once. Then rotate the wheel backward again and see if it grabs the top thread. If it doesn't, repeat holding the bobbin chase and turning the wheel forward until it does.

Once you have the gears basically aligned, you will need to reassemble everything. Put the face plate back on and put at least one of the screws in all the way. The face plate holds the bobbin chase in correctly and if you don't fasten it it will not work correctly.

Now try sewing. If it starts to jam, stop immediately, cut the threads and look at the back. If it's a loopy mess, you are going to have to dissamble as before and again grasp the bobbin chase and turn the wheel forward one more click, then reassemble and try again. Eventually, you will find exactly the right alignment and the machine will sew perfectly.

I just had to make this fix on my own machine...I didn't want to take it in for repair because the bench fee alone would cost as much as the machine did!

There are some great video's on YouTube for help with threading the machine...look for StampTV and you should find them. Good luck!

Janome 6600. Needle came loose &fell down into the bobbin area. Needle did not break off. I took off the plate and manually tried to move a new needle and shaft up/down. needle is hitting something


If you did not get the old needle out, it may be blocking something. That old needle must be removed before you attempt to any further sewing. Try removing the bobbin case from the machine and looking in there to see if you can locate and remove the old needle. Sometimes, I've had to turn the machine sideways or upside down and shake it to dislodge the needle.

============

Open the bobbin area and hand rotate the handwheel while watching the needle action. If it is hitting, you should see it. If that is the case, the machine may be out of time and need service.

My Janome 1600p bobbin case won't lock into the hook. Also when the needle is in bottom position it hits the hook mechanism. The manual doesn't offer any help with this. Any suggestions?


Verify you are using the correct bobbin for your machine. Some bobbins are very close, but any slight variation will cause problems.

Be sure you are using a brand new needle. If it is still hitting, then the machine may be out of time. Search for sewing machine timing or take it for service.

Needle hitting bobbin case


Try a brand new needle. Make sure it is the right needle for the machine and that it is installed correctly.

If the needle continues to hit the bobbin case, then there is a needle/hook timing issue. Take it for service.

How to correct timming on Bernina 930


Rare timing problems with the 930. I created this technical document for Bernina dealers in 1986. Hope this helps.
25838031-wvzw5hiyyg1mbtkxk4f1otgw-5-0.jpg
Also to check for the timing of loop lift, please see the enclosed photos. Note that the needle position is in the right hand position with the hook advancing so that the tip of the hook point is exactly flush with the right side of the needle. (Photos are showing the hook point for training purposes only). These observations and adjustments are always checked with the hand-wheel turned in the DOM (direction of motion). If loop lift timing is off as per the Tech sheet enclosed, the tool for correction is still available. http://www.sewtechnical.com/

Full rotary hook does not fully rotate


The hook timing is probably off. Needs to go in to the shop.

Needle keeps hitting bobbin case when trying to pull it up to top


If the needle is hitting at the low spot when its lowered, the needle is bent or not fully pushed up into the needle bar, could be timing of the needle bar as well.

I think the timing is off on my singer 7430 -- it keeps breaking needles and I can see where the needle hits the bottom of the bobbin casing when it is in the fully down position -- any quick fix?


Drop-in bobbin?

Refer to the maintenance section of the manual for cleaning.

Raise the needle to it's highest position and remove the bobbin and bobbin case.

Clean the shuttle and replace the bobbin case, noting the graphic in the instruction manual for aligning the case into the shuttle.

Turn the handwheel to see if the needle now clears the outer edge of the bobbin case.

My needle jams when it hits the tray the bobbin case is in. It looks as if the timings off because just to the right of where my needle hits is a dip in the tray. Almost as if the needle's too long. I've...


If this is a drop-in/horizontal bobbin, raise the needle to it's highest position. Remove the bobbin case then replace it so it fits snugly into the shuttle. Hand walk to see if the case moves freely in a circle. If it stops, it is not positioned correctly. You do not have to have a needle in to test this.

Once you are sure the bobbin case is correctly in place, re-install the needle. Hand Walk to make sure the case turns without any interference.

If the needle continues to hit, then the machine needs to go into the shop for service.

There is a DIY for adjusting the timing of the hook sewusa.com if you wish to try the adjustment on your own.

Bobbin holder seems to be broke and needle breaks


Hello,
Here are several things to try.

* When you insert your new needle, make sure it’s positioned correctly (usually with the flat side away from the bobbin, but consult your manual), that it goes all the way into the holder, and that the screw is securely tightened.


If there doesn’t seem to be a problem with your needle, try the following:

* Check your pressure foot and make sure it’s attached securely.


* Change your pressure foot Your pressure foot may be bent, causing your needle to hit it.


* Don’t sew over pins a needle that hits a pin can break. Always remove the pins from your fabric before they reach your needle.


* Don’t pull your fabric as you sew. You could be bending your needle back, causing it to hit your needle plate instead of going into the hole. Just guide your fabric, letting it feed on its own.


* Check your needle plate and make sure it's securely in position.


* Change your needle plate. If you’ve been using a straight stitch needle plate (a plate with a small hole, often used for sewing fine, delicate fabrics), switch to a needle plate with a wider hole.


* Check the position of your needle. Sewing machines with zigzag capability allow you to adjust the position of your needle – right, left, or center. If your needle is not positioned correctly, it may be hitting your needle plate or pressure foot.


* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin. There could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

Also, before you start to sew a seam, hold the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.

I hope these solutions help you.
