Singer 111G156 - Timing Belt Replacement

[Constabulary]

The tension release pin is not cut or worn, but will not reach the tension release lever. It is barely even with the housing when the lever is completely up.

I`m not exactly sure but I think I had a similar problem.

Maybe this helps.

In the tension post of the tension assembly is a small pin that pushes the lever of the tension assembly against the pin that comes out of the housing.

And there is also a disc with a small bar in the middle that fits into the gap of the tension post which sits in front of the tension disc plates.

I gave bar in the middle of the disc a small punch so that is pushes the small pin in the assembly a bit more towards the lever and that solved my problem.

Not sure if I described it good enough. But then you take off the screw and the spring of the assembly you will see the small disc with the bar in the middle....

maybe the pictures help

I'm talking about the pin that goes through the machine head, from the lifter bracket on the back, to the front of the machine. It then activates the arm on the thread regulator to release tension. The pin in the thread regulator is fine, if I could get some action out of the other pin.

I lowered the lifting bracket and reset the lifting bell crank, and have my one half inch lift now, but it didn't help with the tension release problem. I'm not sure that I have everything set as it should be (these adjustments are not in the User/Adjuster manual, so I'm just winging it), and I have a stiff spot in the revolution of the machine. I'm not sure if it's an adjustment, or if I still have a dry joint in the machine somewhere. I doubt that this machine has operated for several years. I oiled everything to dripping again and will let it set for a while again to see if it's a dry joint that loosens up.

Thanks for your help on this.

Seems to me in that thread CD I mentioned the adjustment of the tension release and a picture, perhaps not. I'll be interested to see your progress. And yes, it does matter which screws sit where when you time your top and bottom shafts. That info I believe is in another rather lengthy thread about a 111. Enjoy!

I see... Then it is probably the Tension "Dics Release Lever Slide" (what a word) that is worn.

It pushes the pin against the Tension Disc assembly when you lift the lever.

BTW - I have a parts list for the 111G156 but it has no pictures and I have a parts list for the 111W155 with pictures. If you are interested I can post them here or send them by Email.

I was told the G means it was made in Great Britain.

I was told the G means it was made in Great Britain.

I'm beginning to wonder if the G has anything to do at all with Germany on the industrial machines.

The trailing G on model numbers of domestic machines (216G, 431G, etc) indicates German-made machines, but the G and W in the middle of industrial machine model numbers may have more to do with model upgrades than where they were manufactured, don't they? The serial numbers indicate where they were made (W - Connecticut, PB - Karlsruhe), correct?

I have a 211G155 and many of the casting have made in West Germany cast in to them. the serial number is PC66649. Seems to be a lot of confusion about the identtification system

Thanks again for your great threads Eric! They help me a lot.

I will get some photos of my presser bar and lift bracket later this morning. My machine doesn't have the part number 264527 (Tension Disc Slide) on it, and I don't see it listed anywhere in the parts list for the 111G156 machine.

On the timing, I found the other thread, Singer 111W155 Timing/thread Issues, but I haven't read all of the way through it yet. My machine has a safety clutch on it, so the timing marks are on the shaft and a timing plate. I think I put the wrong set screw in the groove, so I'll change it and re-time. Depending on how the set screw holes are bored in the shaft collar, I could see how the timing could be off a half of a tooth or more if the correct set screw was not in the groove.

Thanks for the photos and attachments. Is the machine photo (IMG_2930.JPG) taken of a 155 or a 156? As I mentioned in my previous post, my 111G156 machine doesn't have that part in it, and I don't see it listed in the 111G156 Parts List.
