Do These Machines Have Value?

The pulley is correct! Left and right of the pulley should be a felt disc on either side.

From let to right it should be assembled like this: Nut - spring - washer - felt disc - pulley - felt disc - washer - stud (of course) - check spring

The long curved piece is a foot lift lever. It normally is connected with a mechanism under the table from where you can lift the foot with your knee - or it is connected to a 2nd pedal near your treadle pedal (the one for the motor) so you can lift it with your foot.

Is your bobbin winder missing?

What you should take care of is that the small check spring that sits on the tension stud (and inside the face plate) always rests on the small pin and that the thread travels first around the pulley then over the pin near the pulley and the through the check spring.

Sorry - no tension stud! I thought I had one.

45K parts are hard to find but maybe the tension stud of the GA5-1 or Cowboy CB2500 will fit as they are more or less modern copy of the Singer 45K.

I´d contact Toledo Sewing. I often heard they have parts for older machines and they also have the CB2500 so this should be a good source for it.

Constabulary,

Not a problem, thanks for looking. Thanks also for setting me straight on the pulley and the felt discs, that was a puzzle. Between the parts list you sent and the information on threading and the check spring, I should be able to move forward. Thank you. You're a wealth of information.

No, I don't have a bobbin winder. The seller said there may be more parts and a manual in one of their warehouses. I'm supposed to call him in 10 days to go with him to look, I'll know then if I need one. Hopefully it and the manual turn up. I'll report back on that.
