Clutch adjustment

I tried adjusting the clutch and now have a clicking sound no matter which direction I move it. Any suggestions are greatly welcomed. Thanks.

My first guess: If you are adjusting the play in the pedal, that will not change the "clicking" that is caused by clutch fingers hitting the the throw-out bearing. To remedy the interference between the fingers and the throw-out bearing you will need to adjust the height of the fingers.

Hi,
All 3 of the pressure plate fingers need to be the same height, so the throwout bearing has a flat surface to push on, and so it doesn't feel rough when the throwout bearing first makes contact with the fingers, as you push the clutch pedal down.

You didn't say the year of your Cub.

Below is a How To post about adjusting the finger height, through the hand hole under the clutch housing.
You will need to make the tool shown in the post to adjust the fingers like it shows.

While you are there, it is a good time to grease the throwout bearing grease fitting. They say on here to use cheap grease, so the oil in the grease will absorb into the graphite material of the throwout bearing.
The original throwout bearings have a small hole at the top of them for excess grease to come out.
I would put in grease until grease comes out the small hole. You probably can't see it come out, unless it drops down.

Use a good light to see in the hand hole. It is helpful to have the tractor in a building, so you don't have to look up at the bright sky, from under the tractor.

A clicking sound could be made by the holes in the throwout bearing holder being worn, so the holder moves around some, making noise on the top pin.
If you look in through the hand hole, reach in and try moving the holder up and down, and side to side, and see if it is loose.
The holder should have very little looseness up and down or side to side.

The graphite sticks out of a new throwout bearing 5/16", they can wear down from use.
If it is worn too much, it needs replacing.

Below is a page from the 1955 Cub operator's manual, showing the clutch at the bottom of the page.
