Cub Lo-Boy throw-out-bearing

I have an earlier International Cub Lo-Boy I use for mowing the grass, and something broke in the clutch. When you push it in it doesn"t quite release the clutch all the way, although I have adjusted it to specs. I looked at the throw out bearing and it doesn"t rotate. Is it a solid graphite non rotating face on it that contacts the three clutch levers? All parts seem to be there and working correctly. And I don"t see anything loose or missing or out of place. Any ideas what could be wrong?

Yes, it is a stationary graphite block. It gets lubricated by the oil separating from the wax base of the grease that is squirted in the back via the zerk fitting. The face should extend 1.4 it 2/8 inch beyond the casting.
 
I am not sure of your dimensions that you listed. I looked at the throw out bearing several hours ago and didn"t measure the thickness of the carbon pad on the face of the iron casting. I think it was about 1/4" or 3/8" thick. Are you saying that this should be 1.4" thick? What is the 2/8?

If you have 1/4 to 3/8 face left it is not worn out. Are all 3 adjusting bolts there on the release fingers? If so, you may need to adjust the fingers.
 

What year ? The early low boys clutch was like the normal cub!

When the true "low boys " came out the throw out bearing is back under the seat . They are very differnt designs.

I"m guessing yours is like the normal cub and it is in the bell housing !

There was several differnt ways of adjusting the clutch between models.
 
I have one of the early International Low Boys with the clutch in the bell housing bolted to the engine. It doesn"t have the steel channel side structure like the later ones did. So I assume that the clutch is like the regular Farmal Cubs. One of the children had been mowing with it and then told me the clutch wasn"t working properly. I checked it and adjusted it with the external settings for the pedal, but when you push it all the way in, the clutch still doesn"t quite release all the way, although with a little gear noise it will go in gear and not move. So the clutch is just barely touching and spinning the gears.
