Kenmore 1956 Cycla-Fabric washer timer

[kenmore70]

During this past summer I restored my Kenmore 1956 Cycla Fabric washer and was having issues with the timer.
This machine has an end of cycle bell which rings every 10 seconds during the last minute of the final spin via the intermittent cam according to the Sears service literature. However, it is ringing every 10 seconds for the whole cycle except during agitation. Since it's only supposed to ring via the intermittent cam, I find it odd that it would ring during the first fill when the timer motor isn't even running to turn the intermittent cam. I took the timer apart to see if I could see anything unusual and I don't see anything. All the contacts looks clean and are not worn or bent or burnt, and the cams look to be ok. I also might mention that this model has a kickout switch which also rings the bell, and there is a wire from the kickout switch to the bell. I am trying to see if the bell is somehow receiving power all the time , and maybe that's why it's ringing, but not sure at this point. This timer also has a cam just for the bell, it's CAM8, unlike what's showing in my wiring diagram.

Anybody have any ideas why the bell would constantly ring?

Here are some pics of the cam & contacts. This was the first time I took apart a timer, so it was interesting to see how the intermittent cam is set up. It's the little white wheel at the bottom left and as it turns there is a nub on it which pushes the red pin up to make the contacts connect for the spray rinse.

I do have a question, it looks like the cams had a little grease on them and they were dirty so I cleaned them off. Should they be greased again? , if so what would I use?

There were two different types of bells on mid to late 50s Kenmore washing machines, one just had a little solenoid that caused the plunger to ding when it was activated and it made a second slightly quieter ding when the power was turned off this one was often activated by the intermittent spray rinse cam.

The other kind had a little solenoid in it and a bimetal, and it would ding dong without being connected to an intermittent cam, although it could also be connected to an intermittent cam, and then it would ding each time it was activated.

So if you have the ladder type, it could be activated all the time with power it would ding dong. The earlier type would de the intermittent cam to make it work. I don’t know. Hope this makes some sense.

You probably should put a small amount of plastic safe grease on the cams just so they don’t wear as much, it doesn’t take much.

I confirmed the timer I have does not use the intermittent cam for the end of cycle bell, it uses CAM8 to control end of cycle bell and spray rinses (CAM8 engages the contact for A3 for spray rinse or B5 for bell). The diagram for the timer that I have that I got from the Sears service literature shows CAM3 for the end of cycle bell and I this is not the original timer (it's part 76448) so the wiring may have changed but I don't have a diagram for it. I think the issue is the contact for CAM8 is getting power through the timer somehow all the time causing the bell to ring constantly regardless of where the contact is touching. I know it's a longshot but does anyone have timer wiring diagrams for this timer? I know when I replaced a timer on a later kenmore some connections were a little different but it had a diagram so it was easy to do.

Here's a picture showing the diagram I have (CAM3 for B5 (bell) but my timer has the B5 contact for CAM8.
