6610 Clutch

I have a 6610, had clutch put in when I got it 15 years ago @ 2400 hours, it is now at 2900 hours.

The clutch has always had an issue with disengaging.

It appears to me that the throwout bearing is right at the clutch face, but it takes half the pedal before it starts disengaging.
 
Might be one of the clutches that requires shims between the flywheel and pressure plate but they are missing. That would require extra finger travel to disengage the clutch.
 
How much free play do you have in the pedal? You want about 1 to 1.5" or so. Much more than that and you'll have the condition you describe.

Also, does the clutch eventually disengage if you step completely down on the clutch? If not, suspect seized pilot bearing in the flywheel.
 
I agree with bern.. one other question tho... what kind of clutch disk was used for replacement?? A rag disk or a ceramic? ive seen ceramics that grab hard and hang on they are great for pulling a heavy load... but they suck when used in a loader application..
 
I do not know the clutch, but was installed by the dealer when I got tractor.

It has always disengaged poorly, had to have it COMPLETELY down.

The pedal has to travel down about 2" before it feels like free play, but I disconnected the linkage and the throwout bearing is riding against the fingers with the pedal all the way up.

I think it is a finger adjustment issue.
 
I think you have a misunderstanding as to what free play actually is. Free play is the amount of pedal travel as measured from the upper stop to the point where the throwout bearing makes contact with the pressure plate. Stated another way, it's the amount that the pedal moves easily (with one finger) before you encounter resistance. You want about an inch to inch and a half max. On the flip side, you do NOT want the bearing riding against the fingers with the pedal all of the way up. That would be zero free play, and if not corrected, will eventually lead to clutch slippage and premature failure.
 
It has been that way since I got it, I just pulled the linkage so I could see more what is going on.

I am planning to split next spring and look inside.
