Timing is off on my Elna Air Electronic Model 68

The timing for the bobbin seems to be ''off''.  It appears the hook in the bobbin assembly is not positioned correctly.  Any ideas?

SOURCE: Bobbin drive gear

You need to get the gear from your elna dealer. To time the machine, you want the tip of the hook to pass just over the top of the eye of the needle when the needle is in the left most or right most position depending on which side the eye of the needle will be higher

The plastic bobbin case should sit on top of the raceway, it should slot in quite easily, once the bobbin case is in put the small metal clip at the top over to hold it in place.

The needle won't pick up bobbin thread on mu Elna Air Electronic SU


Has this just started after a jam up? As it's usually a symptom of timing being out.
However first check needle is in right way, flat shank to the back and threading is correct including the take up lever.
If no joy then mechanic service time

ELNA Clutch slip. I have an Elna SU 68 which has served me very well over the years. Recently the clutch has started slipping after about 20 mins sewing. I have stripped and cleaned the pulley and...


Hi Dave,
not sure where you are located for a repairer but the US Swiss Elna Guru is White Sewing Center for spares and repairs.

But I would strongly suggest that you jump over to Yahoo groups and join the group called "Elna heirlooms", then search the threads there as there has been lots of discussions in the past on the Air Electronic drive belts, I can't remember now what the fix is but there are some really talented mechanics in that group, Jim is one who springs to mind.

Also, these machines do have have capacitors inside the air electronic panel for controlling the speed. Also, in this group there is some shared images of manuals/parts/repairs which should be of help to you.

I had a zigzag problem with Elna SU Electronic Air, which I fixed with your solution, but some of the unfreeze liquid had gone down the bobbin winder hole and now the outer wheel on the right side wil


is the belt slipping now? You'll probably need to take off the top cover and see if you can clean up the spilt lubricant off the bobbin winder mechanisim and the drive belt on the right of this. The bobbin winder is friction driven, a rubber ring around a plastic barrel and when you click this over to the right the rubber ring drives off the main drive part of the machine.

removing the top panel is a bit tricky because you've got the handle there too, two screws unscrew it, then you need to manouvere the cover upwards and left to get it out of the bobbin feed part then tip it to the back of the machine to give you a view of the inners. You might want to subscribe to the Yahoo group called "Elna Heirlooms" as there's probably a prior thread on this there, lots of Swiss Elna owners who service their own machines, very useful place to visit.

Something is "clicking" while sewing machine is


Firstly eliminate the needle, put in a new sharp one. A blunt, bent or burred needle will cause clicking, popping or squeaking sounds.

If you can still hear a clicking noise, then it is possible that the needle is touching the hook when down in the needle plate, and this would indicate that timing is out slightly.

If you take off the needle plate and bobbin cover, foot and remove thread, then sew very slowly watching the needle and hook, you may be able to see/hear the point of contact.

I've never adjusted timing on my machines, always left it to a technician. But there is some general images on timing repairs at http://www.sewusa.com/Sewing_Machine_Repair/Sewing%20Machine%20Hook%20Timing.htm if you are technically minded.

Elna Carine Electronic Sewing Machine


You should be able to buy a manual online but it may be a cd or image pdf file. Try www.sewingpartsonline.com or www.sewusa.com. If they don't have the Carina but have the Air Electronic SU, model 68 then this will be almost the same. Main difference is the Carina has the needle up/down button.

I need to thread an elna air electronic su sewing machine


that's a nice machine, one of the last mechanical Elnas with the discs for extra stitches. Firstly, you need to wind a bobbin, always use Elna swiss metal bobbins, with holes on one side only, slightly dished. Put on top of the bobbin spindle and take the thread from your spool on the spool holders at the back of the machine across to the tension disc on top left, its white bump, thread through the tension then back to the bobbin and pull the tail through a hole in the top of the bobbin. Flick bobbin across to the right against the stop, disengage the clutch by holding the outer flywheel and turning the inner towards you. Now press the foot pedal to start winding a bobbin, holding the thread tail so it starts off. Wind one full coverage of the bobbin so that the starting point is covered, then stop and cut the tail off with scissors. Now continue winding at 3/4 speed until bobbin is full, watch as it winds and give the thread a nudge with your finger so it fills top and bottom as well as in the middle of the bobbin. When it is full, the bobbin spindle will stop winding. Move it to the left, cut the thread and reennage the clutch by holding flywheel and turning the inner the other way. Now install the bobbin and click the thread into the tension device, see image.

Now thread up the top thread by taking the top thread from the spool, through the tension discs, across to the eyelet on top, down to the check spring, back up to the take up lever, then down to the needle catching the thread into the two thread guides enroute.
See this image.
10_6_2011_6_43_20_am.jpg

Now thread through the needle front to back, hold the top thread, close the bobbin cover leaving the tail sticking out the top, lower the needle down by turning the flywheel towards you through one cycle and pull the top thread, drawing the bobbin thread up to the top of the needle plate with it. Pull both threads under the pressure foot to the back and your ready to go. Remember, top tension should be on 5 and bottom tension should be on the red 1, don't change it. Brush out the bobbin holder assembly each time you use this machine and add one drop of oil into the middle of the bobbin holder, there may be a red dot or just the indenation. Run the machine for 30 seconds after oiling without thread, slowly to spread the oil through the bobbin mechanism. Standard 130/704H needles, change regularly (6 hours of sewing) and pick right sized needle and type point for the work you are sewing. Good luck with your SU. If you wanted to join, there is a Yahoo group called "Elna Heirlooms" for fellow Swiss Elna owners.
