Does the Chandler-Adler machine use 2 different size bobbins cases?
I was given a Chandler - Adler 167 machine, however it was missing the "tension spring" on the bobbin cap and the 2 small screws that attach the spring to the bobbin cap.
The solution seemed easy enough, buy a tension spring and the two small screws. I found a parts book online and identified the parts and part numbers that I would need.
I found the parts on line from a company in Europe. After exactly one month, the tension spring and 2 small screws arrived. Problem solved!
Actually, only part of the problem was solved, maybe. While the tension spring appeared to be the correct size (the attachment screw holes lined up) but the diameter of the screws was too large.
While I was waiting for the tension spring and screws to arrive (I was getting impatient) I ordered a bobbin cap complete with the tension spring and screws as a back up.
The new bobbin cap arrived with the tension spring attached with the 2 screws. However, when I attempted to install the new cap (28.5 mm O.D.), although it looked the same, it was larger than the cap that came with the machine (24.5 mm O.D.) (but was missing the tension spring and 2 screws).
I checked to determine if the screws and tension spring from the new cap would fit in the old cap, but the screws were again a larger diameter, the same as the ones I ordered and received from the European source.
I measured the threaded portion of the screws I received that were to large of a diameter. The threaded portion measured approximately 2.4 mm in diameter.
Does the Chandler - Adler 167 machine use 2 different size bobbin assemblies?
Is there a good source for these small screws, other parts and technical advice in the U.S. for the Chandler - Adler machines?
Thank You,
