New to me Pfaff 1245 feeds backwards

[Bulldogger]

One last issue, the dreaded “mystery leftover” part...

It doesn’t appear in any of the photos I took prior to cleaning and calibrating the machine. 

Part number stamped on it is  176332 

Any ideas?

Thanks again

Super! Thanks mikesc, it does look like part of the tensioning and take up assembly.

I think that bracket is to control the travel of your check spring.

After following the service manual guidance for calibration I was nearly finished when I realized the feed dog and vibrating foot are moving backwards

This sounds very strange and I don´t know what a Singer 519 is so just to clarify:

Moving backwards in your case means the material is feeding towards you when the lever is down and you turn the hand wheel towards you and it is feeding away from you when the lever is up and you turn the hand wheel towards you. Is this what happens? I know question may sound stupid but you never know...

Constabulary, that is what was happening. It was very odd. It seems ok now that I moved the feeding eccentric for the vibrating presser foot about 100 degrees on its shaft. I will connect the motor this week and test the stitching abilities.

 

I incorrectly noted my Singer model, it is a 591D200A.

Sounds like the feed eccentric is 180 degrees out. No timing marks underneath a 1245.  Can you upload a quick video of the machine being turned by hand so we can see the feet and feed dog in action?

Thank-you Gregg.  That calibration step was challenging, as the feed dog never wanted to sit still as indicated.  Once I got the vibrating foot set correctly, the step you show was easier to get right.

Here is the step that I had very miscalibrated.  The eccentric, number 2 on the figure, was spun on its shaft and very out of cal.

I just acquired a Pfaff 1245 that is probably 50 years old and I am having the same problem with the machine going backwards with the reverse lever down and forward with it up.  Can someone help me understand what I need to do to fix this.  I could not follow the thread to understand where the problem is.
