Concerning the Presser-Lifting Eccentric link with the 2 setscrews on the upper main shaft, the military service document says to loosen the 2 setscrews, hold the link, and turn the hand wheel changing the position of link on the shaft. When I loosen the setscrews I still cannot get the link to rotate and change position. Before I really put some muscle behind this, and possibly mess things up, I would like to ask for advice. Is there something else restricting rotation of the link? What am I missing? 

Thanks in advance.

Uwe your vids are great, a BIG help.

Here is a video of my shuffling foot action. I think I need to move the Presser - Lifting Eccentric Link but it is stuck on the upper main shaft. Any suggestions to fix this would be appreciated.

Definitely not right! As I don't have a 155 I'm reluctant to tell you what to adjust, but besides the external adjusting link the lifting can be affected by some internal adjustments (on the shaft inside the end cover). The outer foot also looks to me like it doesn't have enough lift.I found with my Singers that it took a lot of reading of instructions and adjusting of stuff until I could figure out how to get the feet set to the optimum.

The two circled adjustments will affect the height of the feet and the relative movement of them (yours might be slightly different to this). There is a limited amount of adjustment to get the right spot. I'm not saying this is the answer but it's something to keep in mind, seeing that you don't know just who has adjusted what on this machine.

I'm wondering if whoever worked on it knew what they were doing?

Thanks Dikman post and the tips.

Looks perfect,so what did you do?

Great!  

Bob as you kindly suggested, I started with the Presser Lifting pinch screw, trying to balance the inside and outside foot lift. After that it was evident the needle and the inside foot timing was way off. The only thing I could see that would change the timing was the location of the Presser – Lifting Eccentric Link on the upper main shaft. So I removed the Setscrews from the Link through the access hole, neither of which were "pointed". Holding the Link in position, I turning the handwheel just barely getting the shaft to move. A little at a time I rotated the Links position on the shaft until the needle and the inside foot landed on the product at the same time. BTW - after each little move of the Link I looked in the Setscrew holes for a groove on the main shaft (Simanco #240360) and none was to be found, and no visible “S” stamp on the Link. Next I adjusted the lifting height of both feet with the Eccentric/Cam - the more "wobble" the higher the foot lift. Then back to the PL pinch screw a few more times for fine tuning. Interesting engineering. So I’m glad I can move on to check the needle/hook timing using Uwe’s great vid, and am grateful for all the help I am getting.

 

To summarize for the next newbie…  

 

1. The Presser Lifting pinch screw - adjusts the lift “balance” between the inside and outside pressers.
2. The position of the Presser Lifting Eccentric Link on the upper main shaft – times when the needle and the inside presser touch the product.
3. The lift (wobble) of the Eccentric/Cam Link – determines the height both pressers lift.  

At least for my 1950’s Singer 111W155 version, others may differ.

 

Cheers,

Well done. The interaction of the bits can be a bit daunting at first, but once you've worked it out it's a great feeling of achievement!

Thanks D

I'm thinking ahead to the day when I start on the cosmetics. What is the best way to remove the brass badge pins?
