What type of gears are in a new bernina 1008 and where is it made. are the current ones the same as a mid-1980 model

Bernina used nylon gears in a lot of their machines made between 1950 and ~2000. Some Bernina technicians can get replacements.

After many hours of sewing on denim, the zigzag stopped working on Bernina Record 830

Have you been regularly cleaning and oiling your Bernina? Unless a gear is cracked or something else as serious, it could very well be that the machine has seized due to lack of appropriate lubrication.

How do I unjam the gears in my bernina 830?

If this is a Bernina 830 Record and the handwheel is stiff or does not turn, about 98% of the time the machine needs oil. Another problem could be a cracked or broken gear (one or both of the white plastic gears in the top but unless you are very handy, your Bernina tech should probably take care of this repair.)

Mechanical machines need to be oiled regularly just like your car. If the machine sets in storage for a while or is used often but not oiled or cleaned regularly, the oil that exists in the machine will eventually thicken and acts like glue. (Sometimes you can see a dirty-looking dark gold or brownish goop which is usually old oil.) Then your machine is frozen.

There are quite a few oil holes (both in the top and bottom of a Bernina mechanical) that require periodic oiling (see your machine Manual). If the handwheel is frozen, buy a bottle of liquid Tri-Flow Synthentic Oil (from the hardware store) and put one or two drops in all the spots shown in the manual. (DO NOT oil the two white plastic gears or the metal CAMs!!! NEVER use 3-in-1 oil, cooking oil, WD-40, or a generic sewing machine oil from the fabric store. And do not put more than one or two drops of oil at a time as over-oiling will also damage your machine.)

Then, using your hand-held hair dryer, direct hot air into the internal part of the machine (top and bottom). The metal may become very warm to the touch. Then try to gently move the handwheel. Repeat. Even letting it set overnight may help.

Once the handwheel loosens, slowly hand-rotate the handwheel and watch where metal parts move against each other, put a drop of oil in each of those. Be sure to move the selector knobs and oil where metal moves against metal to keep those working.

To maintain your machine, a good recommendation is to oil every time the bobbin thread is changed, every 8 hours of constant sewing, or every six months if the machine is not in use. Use a good quality oil, ie Bernina oil for "mechanical" machines. When oiling, also be sure to brush out the dust and lint (especially around the feed dogs and bobbin works).

If the oil in your tube looks dark colored, throw it out and get some new. I've run across some old sewing machine oil in the can that looked like dark honey and stunk to high heaven. Get rid of it!

Treat your machine well and it will serve you well for many years.

Bernina 930

How long has it been since you've done a thorough clean and oil? These older mechanical machines are great, however, they do need periodic TLC to keep them running smoothly. You need to open the top, side and free arm. Slowly wiggle the hand wheel and move the selectors/dials, and use either liquid Tri-Flow Synthetic Lube or fresh good quality Bernina oil for CB hook machines. Also, look for the little holes that are oil ports. Stay away from the Basting Stitch mechanism located near the center of the needlebar!!! Do NOT OIL the nylon gears! Don't forget to turn the feed dog dial and oil those moving joints too. If anything is stubborn, a bit of direct heat from a handheld hairdryer will help it loosen.

The following is from a Bernina User Group (a Certified Bernina Technician):
Feel safe putting a drop of oil on any two metal parts that move together. Over oiling will just cause more debris to collect. Excessive oiling will cause failures. Here are some other tips concerning oiling.
Machines with basting mechanisms you just need to stay away from the middle of the needlebar.
First you must be willing to remove covers. And I refuse to suggest anyone removing the back covers of machines with electronics that have to be moved to get to certain oiling points. Especially without a anti-static mat and being grounded.
Use clean sewing machine oil free from resins and acids. Inferior oil may cause a machine to jam, due to the oil drying.
If a sewing machine is kept in the cold it should be left to warm an hour or so just to let the viscosity of the oil in the bearings to restore itself.
Motors are different and the bearings do need oil once a year or so but the motors changed in different machines. Some have obvious oiling holes to get to the bearings, some do not.
A drop of oil under the bobbincase on the hook race (the ledge the hook sits on) is the most often oiled spot. Techs say differently but I just say a drop every 4 hours of sewing or whenever you wind a new bobbin. Or just when you hear noise getting louder there.
As far as grease and gears go, grease is fine when you have metal to metal gears but the fiber gears don't need it since lubricant is built in. The gear grease traps wear particles and abrasive dust particles. Since the plastic is soft and easily abraded, grease would just entrap dust particles which will wear down the teeth, effectively destroying the gear.

Picture of oiling points for the stitch selector (but this is only one small area that needs lube!) See the metal gear just left of center, it has a little hole. That is an oil port. You will find many of them throughout the machine, but also hitting the moving joints will get those spots you've missed.

Bernina Record 930 Electronic, seldom use, like new. Wheel will not move. Was doing stright sewing, machine slowed down then froze. Maching is clean. No instruction book or manual. Machine belongs to my...

Bernina 930 Records are notorious for the basting stitch sticking which eventually locks up the machine. To prevent this from happening, be sure to run the basting stitch for a few minutes every month. If it is stuck, you'll need to take it to a Bernina technician.

If it is not the basting stitch, it could be a broken plastic gear (trip to the Bernina technician) or it needs oiling.

If it is not a broken gear, then it probably needs oiling. Your Bernina mechanical requires regular oiling and cleaning even if you don't use it (ie, every time you change the bobbin, every 8 hours of sewing, or every 6 months if not in use). HINT: recommend Bernina oil or similar good quality oil for mechanical machines, NOT 3-in-1 oil, WD-40, or cooking oil!!! One or two drops of oil in every oil hole and every place that metal part rubs against metal part.

Treat your Bernina well and it will serve you well for many years.

Bernina 730 locks up, had to turn it off & back on 3 times before it would do anything. I switched it from sewing to embroidery, totally locked. It's been to the shop twice recently.

Typically, ther are two problems with locked up Bernina 730's:
1. Look for a split in the worm gear on the cam stack...(white Delrin systhetic gear attached to the steel cams.
2. Look for a crack in the vertical shaft gear...(Delrin synthetic gear as well)
These gears have given great performance for over 40 years and may need to be replaced...

My machine Bernina 830 does not run.

Hi Rose Mary,

I'm assuming you are talking about the original Bernina 830 (their newest machine is also an 830!)

If you've not had your machine professionally serviced in awhile, it could be as simple as a good, thorough cleaning and adjusting. Your machine should be professionally serviced about every 1-2 years....not a bargain service that blows out the dust and puts oil on the hook, but a service that checks all the gears for wear, adjustments, hook timing, feed timing, grease for the gears (if required), removes lint build-up deep in the machine - very thorough.

There are various gears in the 830 that control these functions. It sounds as if one of the gears may be either broken or jammed. Unfortunately, unless you are trained in machine repair, this isn't something you should attempt. When gears are replaced or adjusted, generally the timing of the machine must be reset as well.

We would recommend that you take your Bernina to your nearest authorized Bernina dealer (they'll be trained on your specific machine and have easy access to any parts that may be needed).

If you do not know a dealer in your area, you can search on the Bernina website.

The original Bernina 830 was one of the greatest models Bernina has made and is well worth putting the money into keeping it running. Great machine!

Hope this helps narrow down what may be happening.

Happy stitching,
Kim & Linnette
