Wanted to clean necchi nova and noticed the top screw. I loosened it and then the handwheel stopped rotating. It will start again when the screw is turned a certain way, but goes slow.

SOURCE: Bent shaft

Please do not rate this as it is only an advisory. Your machine was dropped during shipping and the top shaft is bent. The only way to truly repair this is to replace the top shaft which should only be done by a qualified technician. Since it was shipped and it was damaged by the shippers they should be willing to repair or replace your machine.
The other way is to take it to a tech who is willing to try and straighten the shaft. It will never be perfectly true again but it can be better.
I really like the first way better as it is a permanent solution.

SOURCE: Handwheel on Sewing machine no longer moves needle.

Actually you should have a "set screw" in the hand wheel. The set screw is usally locked down tight to keep the hand wheel from spinning freely. I f you can run the machine slowly and hold the hand wheel in one place but the machine continues running, then you do need to replace the "set screw". If you replace it you will find that you can offset some of the machines vibration by where you lock the wheel down. Trial and error is the only way to achive this adjustment, kind of like balancing the tires on your car.

How can I fix the operation of the hand wheel release for a Bernina 807 Minimatic?


Over time the oil in the machine will evaporate or denature, if the machine has not been well lubricated for quite a while, it is likely that the clutch mechanism has gotten dry or gummy. If you remove the small screw in the hand wheel release, you will then be able to unscrew the hand wheel release all the way. Under that there will be a washer with two or three bumps on the outer edge and two or three tabs on the inner edge. Pay attention to how this is positioned. Especially noticing if the tabs are facing toward the machine or away. When you re-assemble the clutch you will want to put this back on the same way. Once that is clear, you may remove that washer, and pull gently on the handwheel away from the machine. The belt is still on at this point so it will not come off all the way. All you need is to be able to see about a quarter of the inside of the inside of the handwheel barrel. Put 5-8 drops of white sewing machine oil inside the barrel and rotate the handwheel. As you are rotating slowly push the handwheel back onto the shaft.

At this point, it can be helpful to run the machine to distribute the oil and loosen that contact. You may find it helpful to hold onto the needle bar, while running the machine slowly to ensure that they machine is not running. Be careful as holding onto any moving part can be quite dangerous. Use extreme caution, or do not do this at all. After running the machine for a bit without the clutch system installed, the machine should be loosened up enough to function properly. You can check this by letting go of the needle bar and running the machine, The needle bar should not move. If this is not the case, repeat the lubrication process and run the machine until it is loosened up enough to work. Once the handwheel will run without the needle bar moving, it is time to reassemble the clutch system. Put the washer piece back on the handwheel the same way it came off. Them put on the handwheel release, and finally insert the screw. Test the fuctionality of the clutch again at this point. With the screw fully inserted, you should be able to loosen the handwheel release about 1/3 of a turn. If it is significantly less than this, try turning the washer piece 1/3 of a turn until it is right. Once you have all that working, you are finished.

This is a fairly simple task, but is hard to explain or understand in writing. If you feel uncomfortable with these instructions, I would recommend taking your machine to a certified BERNINA technician. You can locate a nearby BERNINA dealer at the link provided.

Sewing machine locked up


Sewing machines need to be worked periodically even if you aren't sewing a lot. The oils and greases inside get all gummed up and literally will seize them up. Your best bet is to take it to the pro, pay the $$$ and have them, clean, oil, grease, replace belts, and adjust. OR if you want to give it a try.. DIY... kerosene based cleaner. Clean it well, then oil it properly. Make sure the machine is UNPLUGGED while cleaning.

How can I fix a drop-in bobbin


  1. Cleaning and oiling the machine
    • 1 Unfasten the top, bottom, side and handwheel covers, using a screwdriver. Set the covers aside.
    • 2 Remove the plate that covers the thread bobbin. If it is screwed in place, use a screwdriver. If it is held by a clip or magnet, use a small flathead screwdriver to pry up the plate.
    • 3 Thoroughly clean inside all the openings, using a vacuum with crevice attachment. Remove any stubborn lint, and use tweezers to take out any thread that is wound around the parts.
    • 4 Clean the teeth on the gears, using the tip of a round toothpick to loosen the grime. Vacuum to remove it.
    • 5 Lubricate all the moving parts. Use white lithium grease on the gears, and sewing machine oil on the other parts.
    • 6 Reassemble the machine and plug it in.
    Tightening or replacing the drive belt
    • 1 Remove the top cover, bottom cover and handwheel cover, using a screwdriver to take out the screws.
    • 2 Inspect the drive belt. If it is slack, use your screwdriver to loosen the screws that hold the motor in place, then follow step 4, below, to increase the belt's tension. If the belt is cracked or broken, get a replacement from your sewing machine supplier.
    • 3 Install the new belt. Loosen the motor-mounting screws, and shift the motor toward the handwheel so you can slip the belt over the parts.
    • 4 Shift the motor away from the handwheel to increase the belt's tension, then tighten the motor-mounting screws and check the tension. The belt should flex no more than 1/2 inch (12 mm). If it is too loose, increase the tension.
    • 5 Reinstall the covers and plug in the machine.

Looking for the reverse button on a necchi bu nova


There is no reverse button, it is a lever.The stitch length lever also reverses the feed dogs - when down, it runs forward - at zero, it does not feed at all and when moved up, it reverses the machine. Set your stitch length by loosening the thumbscrew on the vertically moving lever and sliding the plate into position while moving the lever up to the desired mark. Tighten the screw and move the lever down to sew - to reverse just move the lever up until it hits the stop to sew the same stitch length in reverse.

Handwheel Stuck


How about the belt? you have to take off the outer case, usually a few screws and check it. Also, when you have the case off, look for thread inside.

Bobbin spindle won't spin


Check the bobbin winder rubber, it may be worn or broken and insufficient friction against handwheel to turn.........or a thread jam around spindle is stopping the spin. In this case, carefully unwind, DO NOT cut thread.

Cant get machine out of neutral after threading the bobbin


there should be a way to disengage the bobbin winder. I had a machine that had a switch in the center of the handwheel and even though it would be in the off position I still had to turn the handwheel till it clicked.
