Adler 166-102

[PaulMer]

Hook to needle clearance is too great, little less than 1/16".  Experiencing skipping, of course.  Can not find anything from Adler books or videos on how to adjust clearance.  Much different set-up than a Class7  Hook adjustment.

Moved your post to leather sewing machines, you'll get more response here, this is where the machine guys hang out.

Thank you and that's funny.

not sure what you mean with needle hook clearance? You mean the distance from the needle to the hook tip? If you mean the rise from the BDC to form a loop then 1/16" is not enough. Machines with 328, 214 or 216 needles usually have a rise of 3.5mm - 4mm from BDC.

The clearance from hook tip to Needle scarf for the hook to to catch the loop.  Most clearances should be about 0.1mm and this machine is way greater than that.

If I remember correctly, the distance is set with shims

Thank you and I kinda heard that around town as well.  Wanted confirmation.  That will get the hook in place, but, in addition, the hook driver is need of adjustment as well.   There is no needle support/guard and the needle is just floating out there.

Hook setup is the same as adler 205-102 adler 266 and adler 366

(Part 266 15 on this one)

 

I think the hookdriver act as an needle guard

[Michiel]

I think i had some help from the service manual for the adler 366 when I worked on my adler 166

[Michiel]

I might be wrong but i think i have had a 166  where one can turn the race for the barrelhook to move it front and backwards 

you could try that….

In the diagram are the parts behind the Driver shaft "Shim" washers of varying size?  As well as the 3 choices behind the race starting with 266?  Without a Part# list and description, hard to know.

is it a 328 needle?

Here you find the partbooks https://www.college-sewing.co.uk/parts-books/durkopp-adler-sewing-machine-parts-books.html

but i think you have a change your barrel hook race is threaded on the backside and you can make your adjustment by making turns anti clockwise

[Michiel]

I hope I am clear enough my (technical) English is not good

[PaulMer]

Yes Michiel you are clear enough and thank you!  And to Cumberland High Power, it is a 328 needle system.
