Clutch Play adjustment

[Todd8665]

When one is adjusting the play in their clutch when, if ever, do you decide that it's time to replace the clutch. When you are maxed out on the clutch adjustment, and have no other symptoms of a bad clutch should I have the parts on hand at least?

I just know my luck and will be at the bottom of my driveway snow blowing two feet of snow and the clutch will give....

I have never ever heard of anyone running out of clutch adjustment in almost 60 years of driving and working on stick shift cars. If clutch slips with correct adjustment replace it, or at least inspect it if replacing TO bearing. Expensive parts to have on hand if never needed.

I only ask because I have next to zero experience. Working on other tractor repairs I have found things out of spec and/or done improperly. I adjusted the free play in my brakes recently and thought I should check the clutch. Nearly two inches of play before it engages so I tightened it up (seems to shift better). I don't/didn't know if this was something that "wore" in like the brakes, or if it was something that was set improperly from the get go - like a number of other items found on the tractor.

My 2000 was close to the same. 7yrs. and over 400+ Hrs. by the Tach. with No complaints...

i think it may have been misadjusted or adjusted that way by a person that wanted it to feel that way. There is not 2 inches of clutch material on the clutch to wear out i would not think!!!! I havent seen a yanmar clutch in person but no other clutch i have seen has that much.

2" play in the pedal is only about 1/8" play at the TO bearing.

Maybe I am misunderstanding or improperly implementing free play. So i'll put myself out there and give my definition of free play.

My understanding of free play is the distance the clutch pedal moves to the point where it actually begins to push on/disengage the clutch. All the slack prior to doing something.

Given my definition however. There is no way that I can adjust the pedal on my 2210 so that there is only .75 yo 1" of free play - per the Yanmar 276 manual . Sitting here typing i am starting to think that my coupler/linkage adjuster might be put together improperly, or have a the wrong coupler. When i turn the coupler counter clockwise as seen from the front of the tractor(per the 276 manual) both ends of the linkage should push out - elongating the linkage. I think the the rear one is getting longer and the front one is getting shorter...hmmm. Off to check this.

Might as well throw in that I am also questioning if my inertia brake is doing anything.

Your definition of free play is correct. Linkage should get longer or shorter depending on the direction of rotating the coupler. Inertia brake may need adjusting as well.

yea the way it swings and levers i guess your right not that it could move the clutch 2"s out. Wasent useing though i guess:dance1:

Winston, he is saying that turning the turnbuckle thing one side or rod is lengthening and the rod on the other side is shortening. Instead of them both pushing out and lengthening on turning the same direction.

Probably makes no sense.

Yes, I understand, just saying how it is suppose to work. He may need one of these.

Confirmed. For my particular tractor, and turnbuckle(TB). When you turn it counter clockwise (as viewed from the front of tractor) the portion of the linkage that is closest to the rear of the tractor gets longer- more threads showing, while the portion that sticks out of the TB closer to/towards the front of the tractor gets shorter - fewer threads showing. Essentially canceling each other out. I would assume that all things being equal clockwise would simply result in the reverse situation. Seems like someone was not threaded correctly.

Well... One way or another I will make it so that when one turns the buckle it either gets longer or shorter - not simply change the location of the buckle...more to come i'm sure.

Per the inertia clutch. Was working with the tractor this evening. Cleaning up debris from logtruck that delivered firewood and repairing/altering tiewall and slope it holds back along drive where said logtruck hit it with his rear axles on his way out:thumbdown:. I was putting it in creeper gear and going creeper slow peeling the sod and topsoil away. Once my bucket was full i would push in the clutch and simultaneously press the brake. I wanted a higher gear so that I could transport the sod to a new spot. When I would take it out of the creeper gear the tractor would settle or move the instant I popped it out of gear. Is this the inertia clutch; or is my clutch not fully dis-engaging? This could all come out in the wash once I get the clutch linkage to actually elongate and shorten - not just change orientation.

OK back in business. Whoever put this together must have known it was wrong from the get go. The must have gotten the linkage to a workable length, then put it together. Went to local Kubota dealer and found a correctly threaded linkage piece that was a bit long - trimmed it and now I have my clutch free play correct.

glad you got it!
