The bobbin driver assembly is not moving. Is this controlled by a gear that can be repaired or tightened?


1. There are gears that drive the hook assembly. Many machines have plastic gears and can be broken or will dry out and break due to age. Yes, the gears can be replaced.
2. The bobbin driver assembly does not suppose to spin! Under the bobbin assembly is the hook (sharp object) that turns.
3. Test the machine to see if it will sew by placing the needle on the far left and then on the far right. Try both to see if it will sew. If it is sewing on one or the other you will need some adjusting from a qualified repairman. The needle just for your information is swinging too far to one side or the other. The other most likely possibility is the timing is off.

Gears stuck message but gears not stuck


This message is often the result of people trying to close the bobbin door too quickly before the bobbin / hook mechanism has swung in properly. There is a complex system of gearing called the 'console motor / gear' that does all the clever bits like swinging the bobbin out, dropping the feed dogs and operating the bobbin thread cutter and this can get dislodged. Switch the machine off and open the bobbin door. Above the black plastic cover for the rear of the hook mechanism, you should see a small latch which is operated by a mechanism that slides left-to-rightacross it. Check that the 'pip' on the sliding mechanism has not overrriden the latch and is on the outside of it. If it is, you can sometimes carefully push it back to the right-hand-side of the latch and all will be well, however what frequently happens is that the 'drive' end of this mechanism gets dislodged from the console gear and its then a dismantling job to put right ... dont mess about with 820's they are very difficult to set up !!! Something else to try, is to remove the needle and bobbin, switch on the machine with the bobbin door open, then close it and open it again and see if the hook mechanism will swing out. Also, again, without the needle fitted (very important), try rotating the handwheel backwards, but if you come up against any resistance, STOP ... the user manual is incorrect in its advice where it says " use considerable force" - this is an error in translation and I've already had one customer who did 400 pounds of damage in following that advice.

I took out the inner workings of the bobbin holder underneath the machine to try to clean out some clogged up thread, but I can't seem to get it back together. Suggestions?


You should have 3 pieces that make up the parts of the hook and bobbin case that you can take out to clean. 1 the bobbin case, 2 the race ring, 3 the hook. The easiest way to reinstall the hook and race ring is to tilt the machine and lay it on it's back. If you have the bobbin door open, and you rotate the handwheel and look inside the hook area, you will see the driver rotating back and forth. You want to set the hook inside the hook housing facing opposite the driver. As if your putting two halves together. Next install the race ring, shinny side out. Most of the rings have a nipple at the bottom that fits into a slot in the hook housing. Next lock the race ring in place with the 2 black or chrome arms that you swing inward. All you do next is install the bobbin case. Your done.

I had to change the needle when I retreaded it it doesn't catch from the bobbin, the clutch is in the proper position, I've re threaded and re inserted the bobbin, but it doesn't stitch


NEEDLE TROUBLESHOOTING:

Is in backwards, Needle mantra is "insert needle with the flat shank to the back of the machine". Needles have a scarf (cut out) at the back where the hook swings through and catches the thread, if it isn't facing the right way, then the thread can't be caught by the hook.
Is it fully up into the needle housing?
Is it the right needle for the machine. Most domestic machines take the standard 705/130H system needle.
Is it bent, blunt or burred, always start each job with a new needle from the packet, choosing the right sized needle for the fabric weight, and sharp for wovens, or ballpoint for knits.

Good needle chart, threading and machine cleaning info at www.sewing.about.com if you don't have a manual.

If you have tried all these things and still no joy, then it is possible that the machine timing has been knocked out, ie the sequence between needle at it's lowest point and when the rotary hook swings around and catches the thread from the back of the needle. But try the above first and I hope it resolves your problem. Timing is best left to a trained technician.

Replace the needle thread tension dial


If the entire assembly has fallen out you will find if you remove the top left hand cover that there is a small screw in the casting where the tension assembly goes, replace the tension body to the correct position and tighten the little screw.

Plastic casing around the bobbin


That piece is a sweep that helps keep the hook clean. It is not necessary for the machine to use, I have thrown away many of them. If you can get your hook put back in you should be ready to go.
good luck!

Bernina virtuosa 155


G'day.
Firstly, dont flood it with oil - it will end up making a mess for you!
What I'm going to tell you is basic, but work thru it.
1. take out the bobbin case and swing the two latcjes to the side so you can remove the hook. Inspect the point VERY closely. should be sharp and absolutely smooth. ANY burr or nick MUST be removed. (have you broken a needle recently??)
2. Lay the mahine on its back, refit the hook and lock into place. Put in a BRAND NEW needle With the bobbin case still removed and the machine turned ON and in MAXIMUM Zig Zag width, turn the hand wheel in the direction it normally rotates - towards you. When the needle swings to the Left and is on its wasy UP, the hook point must pass behind the needle a little before the eye of the needle reaches the arc that the hook point travels thru. Same on the Right swing. If it does, GOOD.
3. Wind an empty bobbin with GOOD QUALITY THREAD. It should wind on reasonably even and TIGHT. When you push your fingernail into the thread it must NOT be spungy. Insert bobbin into bobbin case (IN THE CORRECT DIRECTION). Hold the tail of the thread and allow bobbin case to dangle, it should not drop down until you give the thread a little jerk. It should drop a little then stop. Insert bobbin case into machine, thread top of machine CORRECTLY. Set top tention to normal, test sew.
Let me know how this goes.
