Need help! Having a few issues!

The question is not "was the clutch tightened down when installed" but "is it still tight when the fault occurs". These screw on clutches are only self tightening if the engine is working against a load. A clutch body is HEAVY and has a LOT of inertia when spinning. What can happen when you rev up the engine with no load on the clutch and release the trigger, the engine slows down fast but the inertia of the clutch can cause it to break loose and keep spinning in the direction that will unscrew it from the crankshaft at which point it can drop to the floor doing about 10,000 rpm with truly spectacular results. Fortunately, your saw has the clutch drum on the outside so this can't happen. The clutch will just unscrew itself until it jams the clutch drum against the retainer clip. Like yours is doing. The only other thing that can push the clutch drum out is the oil pump driver and it can't do it if the clutch body remains tight against it's stop on the crankshaft.

This is the best yet. So the solution, or to be tried, is drop a few drops of Blue Loctite on the threads.

no its not that. If its snug it won't come of to the forward rotating mass and it will self tighten from there. I give it a few little taps with my bar wrench and end of the bar then hit the brake with clutch ingaded.
I have had about 4 clutches spin off on my 357, 262, 266
If its going to happen it will happen right away. Just a preset is needed.

Now I vaguely recall dealing with a problem like that. Not sure if it was my saw or someone else's? I remember it was tough getting the clip off. That's all I remember. It can only be the clutch that is that forceful to bent the clip and keep the drum up. Everything looks good. I would just put it back together.

It will only self tighten if there is a bar and chain on the saw and the saw is stuck into some wood to give the chain something to pull against. Not the same if a saw is reved up without a chain on the saw.

It'll tighten right up with no bar and chain by just giving it a couple throttle blips with the brake engaged.

But I digress...

If the dude hasn't figured it out by now, he isn't going to.

But carry on anyway.

I guess I wrote it a little loose but yes that's what I'm referring to when I said "it will self tighten from there" A little preset will hold it to that stage. Having said that, I'm assuming the last time it fell off. I did set it a bit but not quite enough so I hit the break in the rev a few times and its a done deal.

we won't carry on without you ol' boy.

Who is saying this^^^

[PogoInTheWoods]

I'm such a digresser. So what were we talkin' about, anyway?

Oh yeah..., "a few issues".

Sorry if I confused anyone with any facts.

Now back to the topic at hand.

 

[HarleyT]

Sorry, I digressed.......

Too......

I think that the O.P. has left the building!!!!

 

[Westboastfaller]

Were you just trying to get my attention¿ Well you have it now.
Talk about the facts. You cant talk about digressing from 'discussion' when you clearly throw out a few insults.....at me . We have another name for that.
As far as what you kind of quoted (as you digress) you may want to read what I wrote and read what you wrote. Two completly different things.
???

 

[HarleyT]

Who??
To be fair to all of us confused members?

 

[HarleyT]

Poge insults everbody, if it is him you are talking about.

 

[Westboastfaller]

Oh ..ok...YOU are saying blip the throttle a few times with the brake on to tighten the clutch.

That's not a fact
that's not how it works ol' boy

If people haven't got it by now they never will...haha

 

[HarleyT]

Ok, Poge!!!
I forget that most here have me on "ignore"....

 

[HarleyT]

If anyone makes a post.
Just click enter once!!!
And wait until morning to see if it appears.
If not, it will post a lot of times, and the O.P. will get mad and tell you to leave!!!

But, I think he has left!!!

 

[HarleyT]

I think he is rethinking his crankcase split!!!

 

[overtimegc]

I am so glad I had the opportunity to ask all of the experts on this forum.

Now that I’ve reviewed all of your advice, I can consider my project a total loss. I can say my crankshaft is too short, bearings are failing, the plastic worm drive pushes the clutch up, the clutch unscrews when throttled down, its supposed to do this, it’s upside down, oh and something about the carb. Anyone want a free saw?
