No pto clutch

[jaroban]

I have a jm 224 just recently I noticed
that I was having trouble getting the
Pto to engage. Yesterday it would not
Engage at all. I had to kill the motor to get
It to engage. Or grind the gears. I know
Nothing about a two stage clutch except
It works with the Pto and the transmission
The clutch works fine with the transmission.
is there an adj for the Pto part?

Yes sir, and there are many threads on here about how to go about it. I have not done mine yet, but soon I will. But until then, I can't give specifics.

At the top of the thread page, search "clutch adjust" without the quotes, and enjoy. I will try to do the same, and if I find a very good thread, I will try to post it here.

Edit: Near the top of the FORUM page, not the thread page, click on "search this forum." I am out of time for now, but I liked what I saw of this thread

http://www.tractorbynet.com/forums/chinese-tractors/180231-clutch-adjustment.html

but I am betting there are many good threads. I like to read a lot first before I act.

Just scroll down the chinese section forum a little. I think this was discussed within the past two-three weeks!

General polite internet forum rule is to search first, then ask any questions you may have remaining, referencing the posts you found that lead you to more questions. This "research" should take you AT LEAST a good part of a full day searching/reading... It is quite literally ALL on here. A little bit of search-fu pulls up some excellent archived information.

Sorry, been home sic since Saturday, and I am a little "irritable"...

I am home from work now, so I have time to comment a bit more now. The thread I alluded to above I like because he is having a similar problem to you, and a similar one to me as well.

The pictures are pretty good too. Some of the major points are hit by folks who have actually done the work.

This guys problem (in my opinion) was that he got his entirely our of whack trying to get rid of PTO grinding. We shouldn't have to get ours adjusted crazy to accomplish that. The best we can do is adjust it correctly. If there is another problem, we likely will not fix it with bizarre adjustment approaches.

Every time you stop your tractor by using the clutch, there is some momentum keeping the shafts turning, but after that is gone, you should not grind, or grind very little.

But how often do we really have the PTO clutch fully disengaged, and know the PTO is not rotating. In that state, any surface rust etc would be polished away. A fully engaged clutch does not polish. A fully disengaged clutch with the PTO free to turn does not polish. I think fully disengaged clutch with the PTO shaft known to be stopped will eventually polish things back up.

I think the inertia of a rotary cutter would be perfect to exercise the PTO clutch. Engage the clutch, then disengage, over and over for a little while.

Adjust it properly, it may be good. If not, exercise it. Don't stay partially engaged any longer than you ordinarily would while starting a high inertia load.

I hope this helps in the off chance that it still grinds a bit after being properly adjusted. Other than the exercise approach, all I'd know to do is split it. I've split a tractor before, and it doesn't terrify me, but I have things I'd rather do if possible.

I have read many of the post. The problem I am having is locating the pto adj. bolt. I have both bell covers off I see the adj bolts (#6,#24). With the tractor off the fingers are about 1/4 away from the bearing. When I disengage the pto then start the tractor I can not put the pto lever (right heel) down. When the pto lever is down when I start the tractor . The pto works fine

Hmmm...I don't actually have your model tractor. I hoped it was just like the one in the thread I linked to, and it it is not, I don't really know where your PTO adjust bolts are located. I'll think on it though.

Edit: You say you found 6 and 24, but 6 is the PTO bolt area, and 24 is the main clutch area of adjustment. How am I misunderstanding you?

Edit 2: You DO understand that 1/4 is not right for the main clutch, and if that gap is too large, you can run out of total clutch throw before the PTO clutch is completely disengaged, no? Think about it a bit...the pedal moves and you finally take up that 1/4 inch...you move further and you finally have the MAIN clutch disengaged...you move a bit further and you have taken up the gap behind #6 and you are pushing harder now and ....? Depends. How much gap was behind #6 and how much throw was lost due to your excessive 1/4" gap? Now, I may have some of the fine details wrong about the gap behind #6, but I am pretty sure excessive gap on the main fingers can make you run out of pedal throw before both clutches are disengaged. Figures I am used to for the finger gap are something like 1/8". It seems like a small difference, but it probably amounts to an inch of pedal or more.

Edit 3: I see you are in Texas, but that is a pretty big state for sure. How far are you from Tommy?

Here is a link to a post Greg posted that leads to Spiker's tutorial on it. It shows more than I can tell you about it.

I got the procedure downloaded will
Get it done this evening. Thanks for
Your knowledge help and time.

And if you need any clarification, just give me a shout.

First In used the clevis adj . I have the fingers at less than one eight inch from the bearing. Then I used the procedure provided above. I moved the adjustment (#6) one half turn(loosen). It did not help then I moved the adjustment one full turn. It did not help . Then I moved the adjustment two full turns . I still had grinding when I tried to engage the pto. I put the adjustment bolts back where they were in the first place . At this point I can engage the pto before starting the tractor and use the pto. If I start the tractor I can not engage the pto. Any ideas

I think you went the wrong way on your #6 adjustment. You loosened, but Spiker loosened because PTO engages late relative to pedal release stroke. Yours is early (to hear you tell it,) so early that it is engaged before you let the pedal up at all (thus the grinding.) Your complaint is the opposite of Spiker's, but you adjusted the same direction if I am understanding you and the situation correctly.

Therefore you should close more of the gap in the #6 area, not make it larger. Get that right (about a 0.014" (fourteen thousandths) and once it is right, you have done about all you can do but adjust the clutch bolt stopper bolt in a bit (and adjust the clutch safety switch too.)

If all else fails and every thing is right, I guess you could verify for sure that your spring pins are not broken or wore.

Or ...hook it up to a hard, high inertia load, and start and stop that load several times using only the clutch to polish and run things in a bit. Remember, engine running fast, the clutch pressed full in, but the brushcutter not turning should polish it a little if needed or helpful. Whenever I get to the point you are at (if I am not luckier) I will most definitely practice what I am preaching.

I am out of ideas beyond that, unfortunately.

Okay I went back out to the barn And tighten (#6 OPPOSITE OF THE PROCEEDURE) and all is well .

The finger gap just is. It should be 1/10 inch in a hard case like yours.
The bottom of pedal for the main clutch is set by the #6 gap and the bottom of pedal for the PTO is set by the clutch arm stopper bolt. If a clutch is grinding, you need a lower bottom/stop for that clutch. But that doesn't mean just any amount of lower bottom. You need the exact amount needed for the gears not to grind.

Set #6 until the mains just don't grind, and set the stopper bolt until the PTO just doesn't grind. Overkill on the not grinding adjustment is wasteful of not only available stroke, but your leg energy.

I would say try the 1/10 inch and the 0.014" settings to start. If the PTO grinds, check the stopper bolt.

If none of that helps, live with it, split it, or take it to a dealer, listen to someone smarter than me.

Edit:I think you declared success while I was writing the above. Congratulations!

Did you measure what the gap was on the #6 area when done?
