How can I be sure of that?

I´d almost say the problem sits in front of the machine    *kidding*

The grove for the plunger looks not worn and thew plunger looks long enough. So I only can guess that you don´t push it down deep enough or do not hold it down tight enough or the cam is badly gummed with old oil but then the plunger should still engage.

Try this - when you push the plunger and SLOWLY rotate the hand wheel and when you come to the point where the plunger should engage and you feel it goes over the grove (you feel it and hear it) slowly turn back the hand wheel and jiggle it back and forth a bit until the plunger engages. If you cannot hold down the plunger in the deep position put a screw nut (or the like) between finger and push it in deeper.

I have two machines with this stitch length adjuster (111G, 212G) and on the 212 it kinda feels more "fiddly" (thought is the same system) and on the 111 it works better but still both work well.

was just a guess w/o knowing what is going on on your machine and before I saw the videos.

Hi Folker, 

Thanks for replying. As I mentioned before the machine was working perfectly before, so I know exactly how the plunger works and I actually have 2 of this machines. The pulnger does get into the grooves in order to adjust the stitch length with the hand wheel. Everything was working perfectly, then all of a sudden this happen. Now I can’t adjust the stitch length even when the plunger goes into the grooves. This is what that puzzles me.

Whichever direction I turn the hand wheel it doesn’t come to a halt now, which I thought what you said might be possible

Good morning,

The handwheel is turning the shaft clearly in the first video  - so I don't think it's the set screws there.

You can see clearly in the first video that the eccentric adjusting disk (on the right with the spring against it) is turning along with the main flange (on the left with the screws in it).     When the plunger button is pressed, the tip of the button plunger rod goes into the slot on that disk -- as mentioned and shown in your second video.     But....when the button is pressed that disk then should not move when the shaft turns because the plunger in the slot prevents it.     

In the second video it appears to go in correctly,  but you did not see if it will hold the disk from moving when you turn the handwheel.    Replicate that video but turn the handwheel and see that the disk does NOT move.   If it  turns then your plunger rod is not holding it as it should.   

• Perhaps the tip has broken off the rod so it does not seat as far into the disk's slot and won't hold?     
• Or as Constabulary has mentioned you aren't pressing it firmly enough down into that slot.     
• Or,  if it is  firm but pops out when you turn the handwheel,  perhaps they are bound together with dried  oil,  or the friction plate screws on the side of the flange have been adjusted a little too tightly.

Post a new version of the second video with the button pressed and in the slot,  but turning the handwheel.     Observe  if the  eccentric disk (on the right side by the spring) can be held in place while turning the handwheel.   That is the goal.

 

 

2nd video:    This looks good --  but see if the disk does NOT turn with the handwheel when the button is pushed.

Hi BdB,

Thanks for your input on this, but as I mentioned earlier, I know how the plunger works, and how to adjust the stitch length when the machine was still in good working condition, and I have 2 of this machines, one of it is in good working condition, so the plunger is neither broken, nor I didn’t push deep enough into the groove/slot. See this new video below, the disk doesn’t move when the plunger is set into the groove/slot. The only strange thing is, when I turned the hand wheel in either direction, it doesn’t come to a halt, that’s probably the catch which I can’t figure what went wrong.

Parfektionisto,

Thanks for the clarification .    The only way I can imagine that this would occur as you describe,  is if the pin follower in the eccentric assembly failed or sheared off.   This pin follows the channel in the eccentric ring to cause the eccentric slider to move and change the amount of eccentricity (and stitch length).    When the pin reaches the end of the channel at either end it will be the end of the adjustment and it should stop.   If the pin is gone I would imagine that you could keep spinning it.     Uwe made this very  helpful video that shows the mechanism.  At the 1:30 mark you can clearly see the pin that I'm talking about and how it mates with the ring.    Perhaps it has failed or sheared away. 

Just one thought to try to help you out.   Perhaps others may know of other ways that this could happen.

Good luck.
