Clutch
I think the clutch is going out on my 72. It has 3 “ free play and starts grabbing about an inch from the bottom. It’s not slipping yet, so maybe I can just get away with a new clutch plate and reuse the pp and throw out bearing if it’s not too bad.

Re: Clutch
Hi,
How does the clutch work if you set the pedal free play to 1", like the operator's manual says.
The clutch pressure plate finger height might need adjusting, they might be too low. That can be set through the hand hole. There is a How To for that.
There might be no need to replace the clutch.

Re: Clutch
Have not adjusted the pedal yet. If the pp was adjusted right when new, it should not need any more adjusting.

Re: Clutch
Your statement is correct assuming no wear on the fingers and none on the clutch. Those assumptions have not been my experience. Also it is not unheard of for the finger adjusting bolts/nuts to loosen.

Re: Clutch
Hi,
The bolt at the clutch pedal free play adjustment could be loose and the adjustment changed, making too much free play.
As the clutch lining on the disc wears and gets thinner, the pressure plate fingers rise, making less free play at the pedal.
Usually the reason the free play would increase is the throwout bearing graphite is worn down, or the pressure plate fingers are too low.
Below are pages from the 1965 Cub operator's manual, showing the clutch.
It says what I wrote above in the 2nd paragraph on the 1st page.
http://farmallcub.com/rudi_cub/www.clea ... age-51.jpg
http://farmallcub.com/rudi_cub/www.clea ... age-52.jpg
Setting the free play to 1", measured at the surface where your foot goes, should also provide the 1/8" clearance between the fingers and throwout bearing that is mentioned in the manual.
I would look up in the hand hole with a light and see if everything looks alright.
The graphite material sticks out of a new throwout bearing 5/16".

Re: Clutch
Not for nothing but as I recall, the whole kit was around $100 the last time I did one. Clutch, pressure plate, throwout bearing, and alignment tool.

Re: Clutch
I adjusted the free play to 1”. When you push the clutch in all the way, it hits the pp so I backed it off to 1-1/2” play. Seems ok now.

Re: Clutch
Hi,
Good that you made it better than it was.
If the throwout bearing or holder hits the pressure plate with the free play adjusted to 1", the fingers are probably too low, and need adjusting, raising up.
Below is a How To about adjusting the finger height. You would need to make the tool shown in it.
viewtopic.php?f=141&t=66543
I don't know if this is the Cub you have the throwout bearing out of in your other post.
If it is split, it is easy to set the finger height. They have said on here to check or set the finger height even on new pressure plates, they are often not set right.
1 3/16 - 1 1/4" is the right height, experts on here have said. The fingers should be the same height, to form a flat surface for the throwout bearing to push on.
Below is a pic of where to measure to set the finger height.
The height is set with the clutch assembled on the flywheel, not off, like the pic.
Tighten the 6 bolts holding the pressure plate on the flywheel evenly, it is loading the springs as you tighten the bolts.

Re: Clutch
No it’s a throw out bearing from a different Cub.
Ok the clutch in this one has been good since I bought it in 2006. I only use it to mow, so the clutch doesn’t get that much of a workout. Why would have made the fingers to be too low?

Re: Clutch
Hi,
The parts wear slowly over time from use, the pivot pins and holes for the pins in the fingers can wear, that lets the fingers go down some without doing anything.
If the free play increased quickly, I don't know what caused it without being there to see it.
That's why I suggested before to look up in the hand hole with a light, and see if everything looks ok.
