Question about Bernina 1008

2 Answers

Bent shaft I shipped my Bernina 1008 over seas and now when I tighten the handwheel it "wobbles" when rotated, the belt tightening and loosening with every rotation. If I loosen the handwheel it spins fine. I live in PNG so I will have to fix it myself, but I haven't been able to find a parts brakedown yet to figure out the parts I need to order. Thanks for any help you can offer. Jahn jjharden5@mac.com

Checks:
1. Grab the handwheel and push and pull to indicate any axial play on the main shaft. The machine should not have any detectable end play.
2. Is the handwheel hard to turn other than the intermittent binding due to the handwheel wobble?

Get back to me, and I'll guide you through some other diagnostics.

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.

How can I fix a stuck needle bar on my Bernina 730?


If this is a Bernina 730 Record, it needs to be cleaned and oiled. Do not attempt to run the motor if the mechanics are stuck as it could damage the motor.

Consult your owner's manual in the Maintenance section, use only good quality sewing machine oil (NOT old stale oil, 3-in-1, WD-40, or cooking oil) and apply 1-2 drops every place that metal rubs on metal (while you hand-rotate the wheel). Pay particular attention to your problem areas--the needlebar area and the handwheel area (Do NOT oil the cams, the belts, or the plastic gears!!) To speed it up, you can direct hot air from a handheld hairdryer into the internal mechanics. (You may have to repeat several times over several days depending how "stuck" things are.)

If you are impatient, try to find a bottle of liquid Tri-Flow Synthetic Lube at the hardware store or bike shop and use it in place of the sewing machine oil. Once the machine is running smoothly again, you can use sewing machine oil or continue to use Tri-Flow in its place.

In the future, following the instructions in your manual, clean and apply 1-2 drops oil to the shuttle/race every time you change a bobbin (about every 8 hours of constant sewing), do a thorough but light oil as explained above every 40 hours of sewing, or if in storage or not in regular use, every 6 months. If it hasn't been used in a while, always give it some TLC before asking it to work for you.

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.

Why won't the needle go up and down on my Bernina


Your bobbin wind is on. The hand wheel needs to be tightened in order for the needle to sew.

Barbara. When you removed the handwheel did you find a bit weird looking washer with ears around the outside and to fingers pointing to the center of the washer? If so you probably put that in backwards. The center fingers are slightly bent... they would be bent toward the outside.

Where is the had wheel relaese in bernina 1008


The handwheel is in two parts - the inner part with the grooves on the outside is turned anti-clockwise about a quarter turn whilst holding the outside part to disconnect the drive from the needle bar, when winding a bobbin. Dont forget to re-tighten it before sewing and dont overtighten it otherwise it'll be difficult to disconnect the clutch again.

How do i thread my needle with the singer handy stitch?


  1. Loosen needle screw & insert needle with shank's flat side facing front of machine. Push needle in all the way, then tighten screw to hold needle in place.
  2. Install a fully wound bobbin by loosening bobbin nut & placing bobbin on top. Re-attach bobbin nut & tighten. If standard thread spool will be used, then attach spool pin to bobbin shaft & place thread spool onto shaft. Attach white spool cap on end of thread spool, then tighten. Bobbin/spool should unwind facing forward toward needle.
  3. Bring end of thread through thread guides & over tension control. Pass end of thread through needle eye, from back to front, & pull it out about two inches.
  4. A spring pushes pressor foot onto fabric that is being sewn, so lift pressor foot & place fabric underneath.
  5. Turn large handwheel on side of machine (handwheel can be turned in either direction) to raise needle arm to its highest position.
  6. Holding the Handy Stitch in place with your right hand, press on power switch & begin sewing. Guide fabric (being sewn) with your left hand.
  7. To end this sewing session, turn off power. Turn handwheel to raise needle to its highest position. Carefully pull out about three inches of thread through needle & snip, then lift pressor foot to remove fabric. Turn fabric over & loop needle threader through last stitch. Place end of thread from underside through eye of needle threader, & pull to loop through. Pull to tighten and snip end of thread.

Belts intact, press on pedal, motion in belts, but not on needle end


does the needle go up and down when you turn the handwheel by hand? if so, one of the belts may be slipping - tighten it enough to make it grab.

if the handwheel does not make the needle go up and down, is the handwheel lock for bobbin winding un-locked? if so tighten the handwheel lock inside the handwheel. if the handwheel lock is tightened and the handwheel spins when motor runs the handwheel lock is asembled incorrectly. if this is the case, undo screw in handwhhel lock nut and spin lock nut off machine, then remove pronged washer and turn 1/3 turn and re-install.

Singer 758 adjustments for needle position and stich width


Found this below that may help confirm timing? As for the zig zag one thought is to check for end play in the upper shaft. At the left hand end of the shaft (under the top cover) there is an white plastic "bushing" with one slotted screw - this can be adjusted to take up the slack. It is possible that this bushing is split by the screw which may make it come out of adjustment. Check the other collars on this shaft are tight (hex) - by the belt and near the drive gear. P.S. double check the zig-zag cam is in the correct position (set to straight sew - centre position to install the cam - check instructions).

Timing
Turn the handwheel towards you until the needle is in the lowest position and observe two lines on the needle bar at the place where it comes out of the machine. You have to see these lines. When you find those, you have to tilt the machine on its back and you will see that on the right hand side there is a belt coming down onto a gear like piece on the timing shaft. Move your eyes to the left and the next thing that you will see is a large round gear on the feed shaft. Now that we have determined the difference between the feed shaft and the timing shaft, follow the feed shaft to the left and there will be a small metal piece there with two metal screws on it. Next to that to the left is a stationary metal peice that has a bump on it. You must see these two things to adjust your machine.

Now, to determine if your machine is out of time, turn the handwheel towards you (always turn it towards you) until the needle is in the lowest postion again. Observe the two lines on the needle bar, turn the handwheel toward you until the bottom line goes in the exact place where the top line was. Now look at the needle and hook. The hook should be directly behind the needle. If it is not, we go back to the bottom of the machine on the gear like metal piece that the belt rides on and loosen the two screws that are in the piece. Now if you will remember, this is on the timing shaft. When these two screws are loose, the hook will become moveable. Place the tip of the hook directly behind the needle without moving the needle bar (remember that the needle bars bottom line was placed where the top line was). When you have accomplished this, tighten the screws on the belt gear.

Now you have to determine whether the feed is in time. Again, place the needle in the lowest postion, rise the low line to where the top line was, and see if the line on the feed shaft is directly next to the bump on the stationary metal piece. If not, without moving the handwheel at all (because it must stay in this position to time it), loosen the two screws on the feed shaft piece and align the two lines together. Then tighten the two screws, make a few rotations with the handwheel, and again, put the needle in its lowest position and rise the bottom line to where the top line was. Inspect the two lines on the feed shaft and the hook behind the needle.

If these did not stay in adjustment, re-do the entire process, but be more careful not to move the handwheel when making the tightening adjustment. If you re-do this and it still does not stay in adjustment, you need to replace your timing belt,
