SOURCE: Timing problem

You might have to look at loosening the set screws for the gear on the lower shaft that drives the hook driver gear . Loosen the screws, slide the gears apart, then adjust the hook so it is entering the scarf of the needle on the upstroke. Slide the gears togeather so they mesh again and it should be back in time. There are other factors though such as needle height adjustment which is done with the needle bar and hook and needle clearance (the distance between the needle and hook) which should be about .030. I'm a Bernina tech but many machines work the same principle. Good luck.

SOURCE: Top thread stitches correctly but bottom thread loops.

FYI---- Loops on the bottom-- problem is in the threading..
Loops on the top--- problem is with the bobbin.

SOURCE: My bobbin thread keeps getting tangled and

there is a screw on the side of the bobbin case, which needs to be turned to the left or counter clockwise to loosen the tension and also change the needle because a burr on the end will cause problems with bobbin thread

SOURCE: how do i adjust the bobbin thread tension?

Refer to page 15 of the manual - http://www.singerco.com/accessories/manuals.html

Before changing the tension settings, be sure to thead the machine with the presser foot up as this also has a tremendous effect on the tension and formation of the stitch.

SOURCE: how do you adjust timing on pfaff 138 sewing machine

Take the foot off the machine
Remove the needle plate
Remove the feed dogs
rotate by hand until the needle is at the lowest position
continue rotating until the needle rises 2 mm
the hook assembly should be passing exactly by the scarf of the needle
if not loosen the two screws that secure the the hook assembly and rotate the hook assembly by hand until it is exactly at the scarf of the needle and the distance between the hook and the scarf is .1 mm (almost touching the needle)
tightened the two screws, replace the feed dogs and foot and it should sew perfectly

Bernina 130. The upper needle is working but it does not seem to be abLe to catch the bottom thread. Had this machine for 12 years so I know how to put the bobbin in. Any ideas?


Firstly, I assume you've cleaned-out under the stitch-plate and after removing the bobbin, have removed the hook/shuttle, cleaned the hook race and given the hook race a drop of oil. Whilst you've got the hook/shuttle out, just check that the point is not damaged. Also, if you've got the lightweight hook/shuttle often fitted to these machines (it's black plastic with a metal outer/point), make sure there's no needle damage to the plastic - sometimes this can catch the thread as the hook rotates, preventing the loop from being picked-up. After doing that, check if you can sew straight stitch with the needle in centre, fully left and fully right. If it works in one location but not the others, there could be a number of issues such as timing/synchronisation or possibly the needle bar is offset front-to-back so that there's too large a spacing between the needle and hook.

I have a Bernina Activa 140. The threaded needle is not catching the bobbin thread. What should the needle height be from the plate?


The needle height is best checked by rotating the handwheel until the needle goes down through the stitch-plate (Make sure you're using a zig-zag stitch plate and not a straight stitch plate) and just starts to come back up again. Stop there. Gently push the needle bar to the right until the needle is at its furthest-most travel right (next to the right-hand edge of the needle slot). Tip the machine backwards slightly and drop the bobbin door; take the bobbin out. Open the hook/shuttle retainer, but leave the hook/shuttle in the hook race. The point of the hook/shuttle should be somewhere near the top, just below the stitch plate. Slowly rotate the handwheel until the point of the hook/shuttle passes just behind the needle; The point on the hook/shuttle should be just above the thread hole in the needle - if-so, the needle is at the right height, assuming the machine is properly synchronised. If its at the wrong height, you would need to have the needle-bar mechanism adjusted to put it right (relatively simple) - you cant just try and fudge it by adjusting the needle height using the needle securing screw. If you need help with re-setting the needle bar to get the right height, I can help, but you really need to be sure that the machine is properly synchronised first, so this may not be the total solution. Hope this helps.

My bobbin thread keeps looping and the top looks fine but pulls out easily. I tried adjusting the top tension, but it didn't help. What can I do?


There could be several things that could cause the machine not to pick up the bobbin thread.


1. The upper thread could be tangled. Remove the thread completely from the machine. The correct size spool cap should be used for the size of the thread spool. Re-thread the machine according to the directions in the manual.


2. Remove the bobbin and make sure the bobbin is threaded properly in the shuttle race. Remove any loose threads or lint in the shuttle race.


3. You could be holding the needle thread too tight. Hold the thread lightly to keep the end from going down into the shuttle.


4. The needle could be thread incorrectly. Thread the needle eye from the front to the back.


5. The needle could be bent or improperly inserted. Install a new needle with the flat side of the needle facing the back.


If the problem persists, your machine may require service.



The bobbin thread tension has already been adjusted at the factory for general use. For most applications, no adjustment is needed.

When sewing with then thread on thin fabrics, the thread tension may not be adjusted adequately with the upper tension control dial. Therefore, the thread tension must be adjusted according to the procedure described below.

If bobbin tension is too loose and locks appear on the surface of the fabric, decrease the thread tension by turning the dial to a lower number.

If the result is still not satisfactory, then adjust the bobbin thread tension.

Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the screw more than one full turn.

Older 830 will not zig zag stitch. leavers and gears move fine. The needle moves back and forth - left and right but it doesn't pick up thread from the bobbin on the left side so it does a strait stitch...


Firstly, make sure you have fitted a new needle and that you have cleaned/oiled the hook race. Unfortunately, if you are finding that the machine will pick-up the thread and stitch OK when the needle is one side of the stitch-plate, but not when its on the other, it suggests that the timing/synchronisation is out and will need to be professionally adjusted. You can check the timing by adjusting the needle to its right-most position, remove the bobbin case, rotate the handwheel until the needle has gone down through the stitch-plate and is just about to come up again. Stop there. Tip the machine slightly back and release the black plastic hook/shuttle retainer by pressing the metal lever on the top-left side of the bobbin door, so that the hook/shuttle retainer pops open. Drop the hook/shuttle retainer, but leave the hook in place ... be careful that it doesn't drop out and slowly rotate the handwheel until the pointed part of the hook/shuttle rotates clockwise to the place where its point is directly behind the needle. Look carefully and you should see that the point of the hook/shuttle is just above the top of the thread hole in the needle. If it's much lower or higher, the timing is out and will need to be adjusted.

Top thread is picked up by hook, but never picks up bottom thread. I know how to adjust needle height. How do I adjust hook timing?


try turning the bottom spool upside down. looking at the shuttle in your palm the thread needs to be on the left hand side winding / facing anti clockwise to catch in the hook see link below for

When drawing thread up from the shuttle needle wont go down


Sounds like your hook to needle timing is off. When you sew through thick materials, a lot of machines have issues where the needle sticks in the fabric but all the internal parts shift and this causes the hook to needle timing to go out. The begging signs of this is skipping stitches. You will have to have you local independent sewing store do this adjustment for you

Hope that helps :)

Singer Model 5050 Timing Problem


Actually,timing of needle vs, shuttle is not very easy job several factor you should check on.There is belt ot sometime a shafting with worm gear and helical gear under machine w/c drive the shuttle with the bobbins in timing order,Any one of them is present on the timing adjustment can be done by releasing the belt or the helical gear,besure machine is unplug then set all mechanism on low dead center meaning the needle move to utmost lower position catching this by the shuttle and bobbins at center position.No motion applied if this was set up,engage the belt with pulley and the bobbins link holder tigh allenscrew besure the needle is lower dead center at the center of shullle bobbins catching needle without motion when setting back at original position.If this was made manually move it on handwheel going up and side down the needle gradually if the needle move freely several time and it was catching this by the shuttle hook bobbins.if ok put thread bobbins and upper thread dial tension with the needle.Move machine on handwheel try to catch the bobbins thread,If this so your machine is ready to sew again if problem occurs on alignment repeat adjustment on perpect alignment,besure all parts on upper casing of machine specially two drive gear are in normal alignment.

Sewing machine repaired but still bunches up


Either no tension on the top thread or damaged needle plate or possibly a broken hook driver spring

I would first make sure the thread tension is adjusted properly. if this does not fix your issue, check the point on the shuttle hook and make sure it is not broken off. it should come to a needle sharp point. if the tip is broken off it may not pick up the thread from the needle properly. then double check the timing and the needle shaft depth. first, make sure your needle is fully seated and tightened down. the groove in the needle should face forward. there are two timing marks on the needle shaft. at maximum depth you should see both lines and the top line should be right at the bottom of the needle shaft bushing. then as the shaft goes back up, when the bottom line is at the bottom of the bushing the point of the shuttle hook should be right behind the needle and centered in the indentation on the back of the needle. you may need to make minor adjustments on the needle shaft depth depending on what brand and type of needles you are using.
