Jimbob Report post Posted December 17, 2012 My dear Adler 105-64 startet skipping stitces in reverse....then more, and some more.... All is well in forward motion, no problem there....feed dog is tight, needle is new, and it stitches exactly back into the needle holes....if it sew sperfectly forward, it could not be the timing, wonder what efects the reverse stitching to skip stitches so badly... Seems if I go a bit faster in reverse it does better....but no need to go fast in reverse. Maybe some of you all have an idea.... Thanks for any info...

Trox Report post Posted December 18, 2012 Hi James how are you? You have owned that 105 for a long time now, if you have not had it serviced now is the time to do so. If you are using a new Schmetz needle (the right size for adjustments; 328LR metric size 200) and not using any thread oil (some makes the thread loop stick to the shuttle), it`s probably a timing issue. I tried to write down the way to do it here, however it takes to long. You better get hold of a service manual and read it your self. I do not have one for the 64 subclass, only for all the other subclasses of the 104/105. There are some manuals available on http://www.sew24.blogspot.no/p/downloads.html too. You can also ask Thomas Brikhoff (head of DA spare parts) if he has the 64 service manual. Or you can probably use the 205-64 service manual, it has the same feed and shuttle as yours (same machine in new wrappings). It gives you a general idea anyway. You do not need all the special service attachments to adjust your timing (as they say you do in the manual). The important thing is that the hook tip is over the needle eye in the loop stroke position. And also is so with tensioned thread in it; there is a play between shuttle and shuttle driver. The position of the shuttle in the loop stroke when the machine is turned by hand (without thread) will be different from the real sewing conditions. (with thread and tension on it, the shuttle will move against one side of the shuttle driver, different timing reading) I have your Email address and can send you the one I have for the 204-64 and 205-64. Pay attention to the adjustments rule nr. 5; producing reverse stitches. A quick way to check the timing is to move the needle gradually down wards in the needle bar and try it. Move it down a bit, lock and try sewing, repeat if necessary. This instead of adjusting the needle bar up and down, if it works you know where the error is. When you do a service do all the adjustments in the right order. A good result may depend of it, start with rule 1 and go true them all. Clean and oil. Good luck PS. do your email server support big down loads 3,42 MB? If not I can load it up to a web link you can download it from. Good luck Trox Quote Share this post Link to post Share on other sites

Good luck Trox thanks a bushel for all the good info....will have to down load the repair manual....seems to me when it works forward (timing....why does it not work backwards...?) same needle position to hook....just different turning direction...hmmmmm...?? Will see what I can do, so far this has ot been a big issue.....but it needs to be fixed. Again, I will check on the manual and report back! Greetings to you from me...

James Hi James, No it is not the same needle position to the hook, It is a needle feed machine and the needle moves with the stitch length. Or when you changes from forward to reverse. So if it is knocked out of timing a bit it can still work good forward and miss stitches in reverse. The timing of the hook position is different in zero stitch length than in maximum reverse length. "The position hook tip should be 0,5 mm behind the right needle edge, when the upper edge of the needle eye is flush with the lower edge of the hook tip". See pic 9. This is data for the 205-64 machine, I send you the download link in an PM. You can read how it is done on that machine and compare yours settings to it. The pic 1 is the loop stroke position set with the special tool at zero stitch length. The pic 2 is the distance between the needle and the needle guide; 0.2 mm with Schmetz 328LR size 200 (when the shuttle is removed) The down load link is available in three days and sent to you in a PM.
