122 Clutch Question

[Rhoderman]

My 122 has been messed with before I got her, and I don't trust much of anything I find any more.

I've got the clutch out, and snapped this just as I took it apart:


That just doesn't seem right. I think the throwout is installed backwards. Am I correct? And that washer, where was it really supposed to be? Does it belong at all?

Here's one way I think it should work (note new washer and other parts):


I don't see that washer in any manuals, and the throwout is usually too small to see, or at least unclear in the pictures I've seen. Is the washer supposed to be there? Does it maybe go in front of the teaser spring? Help??

I'd hate to put it all together and learn I messed it up.

Thanks all!

You are correct about the throw out bearing being in backwards, it goes the way you have it in the second picture.

You are also correct about the washers, they don't show up in any illustrations anywhere (so far as I know) but it seems like every one I take apart has one or two of them in different places, I may be crazy but I like to have a washer in front of the teaser spring.

I also like to put an "L" shaped pin in place of the one that holds the lever to it's bracket, an "L" shaped pin won't rotate in the hole on it's own from the engine vibration.

I read on another site somewhere cant remember exactly where that a machine washer where the one is in stalled in the first pic would help keep the teaser spring from breaking.Not sure if this helps but thats probably where the washers are coming from.Mine had one there to when I took it apart.

Thanks for the feedback. Here's why I'm leaning toward putting the washer where I show it in the second picture:


That end of the bearing is smaller than the spring by quite a bit. And, if it wears enough, it might start to eat the seal/shield on the bearing. I'm half tempted to put a washer ahead of the teaser spring, but I can't get the teaser spring to grab on the edges of the slots, so maybe it isn't necessary.

Still open for comments. I won't be putting it together for a about a week, so I have time on my side.

And by the way, the shaft was very easy to make. Thanks to Matt G. and others for suggesting it.

There is supposed to be a washer between the spring and throwout bearing, and another between the rear spirol pin and spring.

BTW, I never use a spirol pin to hold the spring compressed; I get a 5/8" locking collar and clamp that on instead. It's one less hole to drill. I can then increase the compression over stock, or run an 800# pulling spring at 5-600# instead of the full 800. I can also adjust the spring while the clutch is in the tractor, depending on what I'm doing with it, all in less than 10 minutes.

Thanks Matt. I can see where a washer on both ends of the big spring would allow it to rotate as it wanted and maybe not wear the pattern of the spring into the shaft as happened with the original one from mine.

I really like the idea of a clamp for spring tension. The thing that has me puzzled is how you adjust it when the spring is loaded. I'd imagine you have a special tool you've come up with to allow you to compress the spring easily, right? Since I don't plan to pull with this one, I'll use the spirol pin hole I've drilled already.

I'm waiting on the clutch disc. I was an idiot and ordered all the parts, but forgot to order the clutch disc itself! I meant to order that Kevlar disc separately, yeah, that's it, really it is...

[Matt G.]

Yep, I made a spring compressor.



We'll see if that picture decides to show up...

This is one of the most helpful threads I have seen and I'm not even working on a clutch at this time!!!!!!

Matt,

Do you have a picture of that locking collar installed?

[Rhoderman]

It's all back together. Waiting for the engine to be finished.
Here's a pic showing the finished assy, and the old parts.


I made a new L-Pin. Here is it alongside the old pin. I think I eliminated about 1/8" of slop with a new pin alone.
The old firewall bracket was toast too, probably another 1/8" there...


Thanks for all the help!
