seth thomas mvmt no. 120

[Carroll Hardin]

A Seth Thomas NO. 120 is giving me trouble--
It would run great for about 2 days and just stop. I noticed the time spring,( enclosed in it's box)was appearing to be rubbing against the wheel. After removing the spring from the barrel
it was obvious that the spring was badly coned and catching on the brad heads which hold the click assembly onto the wheel.The spring had been
previously installed and cut to fit this clock.
A new spring of the correct size was installed and now the clock won't stay running like before.
Any suggestions appreciated.Thanks, Carroll

Carroll on these movements the bottom halh of the plate that you remove to get the springs and barrels out--the top of this plate screws to the upper half of the front movement plate --the bottom of this lower plate is secured to-I believe to three posts,their are 3 spacers that go on the post before the plate is installed-the spacers are the same thickness as the upper front plate,many times these spacers are not observed when putting the movement in to where ever you clean your movements - check the bottom of where you cleaned the movement- they may also have been missing due to a previous repair. Without these spacers the lower front plate will be cocked over enough to stop the clock after a day or two as the spring winds down- if the spacers are lost I have used clock bushing of the same thickness as the upper plate.

Carroll, at the clock shop that I work at, we have stopped taking in this clock for repair. Most of the ones we restored have been comebacks. There comes a time that you just have to make a business decision and move on. Bob V.

Jack and Bob,
Thank you for your replys about the Seth Thomas 120 movement. The bottom part of the plate is indeed sitting on three posts. As that part of the plate rests on top of the top half, there is a gap created on the middle post, which has the spacer on it. Guess I will completely dissasemble it and start over. Am determined to fix it, even though there have been previous repairs. They are mean buggers. Thanks.

All three post require that same spacer that is on the center post. The way it is now you are pulling the ends of that lower plate down and this will cause the loss of power you are getting after a couple of days. JACK

Hello Carroll...Good luck with that ST-120..This might be of interest to you..



I should have seen that first off but..Oh well!!
Sometimes fixing other "peoples" fixes take longer then a major overhaul..

Thanks for the 120 Pic, but I didn't get your comments. The spacer is on the bottom center post but spacers on the other two would be detremental would they not?
Thanks,

Carroll

Carroll..Jack said there should be three washers..Take a look and make sure the "sub-plate" is flat when together...Probably not with only one washer...I forget..

I was saying to look at the "snail" hitting the "rack" at the three o'clock position..This stopped the clock everyday..Check and make sure yours is not touching at that position..

George,

Thanks again for your reply about the 120. The shadow on the pic kinda hid the snail so I didn't realize your thoughts on this. I hate to beat this to death, but I have a spacer on the center post, which raises the bottom of the plate even with the top part of the bottm plate. The top and bottom of the lower half of the plate now measure the same in between, so I don't see how any binding happens there. My opinion is that a spacer on all three posts would just re-create the problem of binding.
Thanks to all for your comments and help.
