Like quite a few already posted, the 1st thing I thought after viewing images of the machine was that I've never seen a Juki like that.

Consew sells a variety of servo motors, what model do you have that you dislike? Some of their motors are very, very good.

CLICK ABOVE TO EXPAND IMAGE LINK TO FULL BOOK; http://www.keysew.co...W2BLLSW28BL.pdf See page eight of above Adobe .pdf link for description and install notes; this knee lifter appears on many makes and model machines. This very common knee lifter is the same as on a Juki LU-563 or Singer 111W155, for example. Above pic is from a Highlead factory knee lifter, but this is entirely different than what is on a Consew 226. Common machines for this pic posted by dirtclod are for example a Juki DNU-241, Conew 206RB, and many, many others.

What subclass is it? It's going to be one of the four; 204-2, 204-64, 204-102, or a 204-370? All high quality machines, but the subclass is important to know if your asking about a specific machine here.

http://keysew.com/We...ew225REPAIR.pdf Found it and uploaded it to my website for whoever still wants it. Had a hard time finding this in my archives, I knew I had it somewhere. Oldie but goodie for sure.

I think I thought I used to have that in my archive of files. I spent about five minutes after lunch, but no luck. I will upload to my website for download if I can find it a bit later on.

What you need is 135X17, also know as DPX17, as well as 3355.

We have two of the Adler 20 class machines, still trying to figure out what to do with em.

Take the recommendations and learn from our experiences setting up skivers, use a clutch motor. Good half, or like said, 3/4HP motor. Even a very good servo motor that we commonly use on a walking foot machine will not have sufficient power, and like said, speed control of the bell knife is not critical. Good luck!

STOP: Hammer Time!

No.

This may be of some use in shedding some light on this subject; http://keysew.com/Webpages/DemoImages/Groz-Beckert_Needles_for_the_processing_of_leather.pdf

Looks like both someone and the machine got hammered! This is the best I could come up with.

Well, certainly a conversation piece, no doubt. First thing I was wondering is what needle system they were using. Specs on website state it's custom. That means 'make your own when they break and you've run out'. Good luck with that. Very good looking machine, highest lift lockstitch I've EVER seen. But, again, this is not a production model, and everything is custom. That means when your machine has problems, you've got PROBLEMS!

Can't say much other than what I know about; the Highlead in mention is good machine, we've sold a few of them. Our supplier stocks and sells a lot of them. One thing about this machine, as mentioned already, machine really must be setup out of the box, or you will likely have trouble. After that, it's really a good quality machine, like all the Highleads really.

Good information, Trox! One thing..the 267-373 is no longer being sold by DA. This has been the case for some time now. The Chinese 267-373 machines were not too bad at all.

I think I can recall some Consews being labeled as 206R, without the B. R is for reverse, B is for big bobbin, and FS is for the binder. But, as all said, a Consew 206 series all use the same big bobbin hook, and all have reverse.

The extra wire is for reversing the direction of the motor; usually the motor has a diagram on the end bell cover, either on the outside or sometimes on the inside. It will show the line in (power) and then the direction of rotation, and what wires to use. Some use numbers or colors to designate the wires. Good luck, and be safe doing this.

By the book, if you will, Juki LU-1508N/1508NH can take either or needle system 190 or 135X17 (DPX17). The problem with the 190 system needle is that it's very long, and will cause more deflection as it tries to penetrate the material. If you choose to change over to the 135X17 needle, you will have to adjust the needle bar height. As for the upper tension, I've always found it comical, in a sewing machine guy kind of way, how Juki would 'feature' a dual tension mechanism. If it were so effective and important, how come they don't put a dual tension mechanism onto their LU-1510 or LU-1560 machines? Only reason they have this on their single needle is so they can keep on consistent tension assembly across the board for their LU-1500 series machines. Other than that, I see no benefit, unless you are using a heck of a lot of tension, and can spread out the tension pressure so your not 'crushing' or distorting the thread as it passes through the mechanism.

Wolf, If Bob is doing a good job for you, and I'm sure he is, contact him, he will know what to send out for you immediately.

Yup, 331K4.

Of course, like said, check fuse. Also check the motor brushes to ensure they are in good condition and are not hung up. We warranty our motors for one year, and will simply send a new motor out to the customer. Then motor goes back to the supplier for credit. Again, this is us, and we operate.

Never thought this was difficult to locate, but here it is; Here is the link for Highlead factory in China I do have some intrest...who is calling what a copy?
