Kobe 1541S alternating lift height adjustment

[plinkercases]

Thanks I look forward to following your guidance here.

This is not in the engineers book nor the owners manual.  I'll try not to go off on a tangent here.  There seems to be some confusion about presser feet climb and lift of the alternating presser feet.  Juki climb device, or DL device, is for the LIFT of the presser feet.  Such as  the difference between two pitter pattering feet on the low end, or two feet taking big tall steps over an obstacle, if you will.  This does not adjust the difference in feet lift. For example, if the inside foot is lifting 2mm and the outside foot is lifting 6mm as you cycle the machine.

If the feet are lifting to to different heights, try this.  See attached image.  Remove the back cover and rubber dust cover and you can access this clamp held in place with metric hex cap screw.  Lift the higher foot the difference of the two, loosen the screw, the presser spring should then drop both feet to the plate.  Tighten the screw.  Usually, this takes a few attempts to get this just right. Check with a flat head screw driver or something to see that both feet are raising to equal levels.

So, for example; if the inside foot is lifting 2mm, and the outside is lifting 4mm, raise the outside foot 2mm, loosen the screw, foot will drop to the plate, and then tighten and check.

This is the same adjustment for many other model machines, not just this one.  Hope this makes sense.

Thanks Gregg for the photo! 

I found another manual this procedure is in, though its been hidden as I stuffed it in a sleeve folder in the binder. 

Its called; Juki instruction manual #no.05

and with a series number 29349503.

this has all the languages and its clearly a great manual in actual operator sense, better than a lot. In that aspect I totaly recommend it. 

In any case I hadn't looked at it well enough but this adjustment, its in there! On page 28. Instruction no. 19. This description is much much more normal, I believe or it is for me anyway. ( i dont need as big of a sign )

But this manual here its not the quality of that engineers manual that is linked with a big thanks to dikman.

I have that one printed and in binders for each of the 41, seems handy and I write down what and any dimension i used in each step in adj. specs. 

Maybe a slight issue in ocd ness, yet its a record.

 

Have a good day everyone

ps:

 

This is for the "pitter patter" or "high climb" of presser feet, same as what the DL or dial on top of the machine does.  This is just not as fast or easy to adjust, but it is the same adjustment.  This adjustment has nothing to do with the variance in presser feet lifting.

Thanks gents!!! Between those 2 simple adjustments i now have a very usable machine  stepping high with an even gate! And no mechanic fees and dragging to 400kms to get it done.

Good to hear.

I was just asking this very question on another thread, before I found this discussion from 2019. 

@plinkercases seemed to have resolved it all and said "stepping high with even gate". May I ask how high? I have tinkered around this adjustment of my DNU1541 for a while now, the only time I could get it "step high", is when only ONE foot steps high, when I make the lift-height of both foot equal (like how it came from factory), the max height has to be compromised. 

Say when the presser foot was able to achieve almost 0.5 inch max height, the center walking foot barely lifts at all, and vice versa (although I couldn't get the walking foot to achieve the near 0.5" height). After playing around with the "foot drop" adjustment with the top hex screw, I was able to make the walking foot lift higher than the presser foot (this is how I need it, best suited for my leather jacket need with bulging/ bumpy sections, I need the center walking foot (where the needle is at) to walk over the bump, and with some push and perhaps knee lift, I can manually walk over those seams), but the compromise is that the max heigh of the walking foot lift, now, is not as high as it could be.
