An insertion tool usually means its used to install something then removed after installation. In this case I would assume it's used so that the sprags don't get damaged while sliding the unit onto the shaft...so keep in mine it has to come off..or slide out after the bearing is in place. Afterwards the bearing may spin both ways with just a normal spin but a quick snapping spin in the direction of shaft rotation..ie clockwise as you say, should be enough to engage the sprags.

Sorry man, I didn't follow that.

I used the insertion tool to slip the bearing on the shaft.  You're probably right, it's there to protect the sprags from getting damaged, and it definitely comes off.  But after it's off, my bearing only moves counter-clockwise.

I know for certain the shaft, while facing it, spins clockwise. I'm getting stuck in my head...
Is the bearing supposed to spin the same direction as the shaft or the opposite?  This bearing does not spin both directions and I suspect the only reason my old one did is because of the missing teeth not gripping anything at all.

EDIT:  I re-read your post and I think I understand that you're saying that the bearing should freely spin in both directions but a quick motion should throw the sprags into the shaft and stop the spin.  Is this what you're saying?

The new bearing only spins one way.  I used the insertion tool to get it on the shaft and pulled the insertion tool off and the bearing only spins counter clockwise regardless of how hard or quick I try to spin it.
I'll go out and turn it around and test that direction just to see if it spins BOTH ways but locks in one direction if spun quick...


EDIT 2:  Just reversed it and for certain it locks up without giving any pressure at all in one direction but spins freely in the other.

So now, I don't understand which direction it's supposed to spin and which way it's supposed to lock.
Engine shaft spins clockwise.  Which way is the bearing supposed to lock, same direction as the shaft or opposite?

Sounds like it just fine. Some people said theirs spun in both directions but if it was working like it should, it should only spin in one direction,counterclockwise. If you try to turn the bearing the same direction as the crank turns, clockwise, it should lock-up....so it's good the way you first had it.

I am even more confused now.

I found a Russian video on how to change the strength of the secondary by moving the spring, and this has nothing to do with me, but what I found interesting is that they don't seem to mind that the secondary is spinning at idle.

Yet, in this one, this guy CLEARLY has the same blown-out bearing like what I'm dealing with.  When he starts, the secondary is spinning and when he's done replacing it, it's not.  Unfortunately I can't tell which direction this guy is installing his bearing.

The guy clearly has the bearing in backwards. It is NOT supposed to spin the primary at idle. The one-way serves as an idler bearing at that point for the belt. He will break the sprags as you did and he won't have any engine brake...IMO.

Dude, I so appreciate your input.
I'm going to install the bearing so that it spins opposite of the direction of the shaft.
This has been quite a learning experience, and I very much appreciate the knowledge I've gained.
THANK YOU!!

Well, I just watch a number of them that do spin at idle...now I am confused. That goes against all that I understand about it's operation. I am going to keep looking. Wait a bit until we are 100% sure.

OH...Wait..the clutch will spin...it has to!...sh*t...its the outer race of the bearing that won't be..wow..talk about over thinking. Yeah so put it in like I said..you'll be fine.

I guess I was thinking of the 800s with the wet clutches where the one-way controlled the entire shaft. On yours if the shaft and clutch isn't spinning, it won't sling-out the flyweights and engage the belt...Daaa. Man I just need to go for a ride...lol

Hahaha! I definitely fell into the classic overthinking on this too.

Thanks again, I really appreciate it, and best of all, I know I learned a LOT about how this all works.
I'll make a post later if I can get the job done today (Friday's are pretty busy for me) and let you know how it works.  I suspect it'll be perfect.

Fixed.

I put the bearing on so it spins counter-clockwise and put it all back together and it works just like it did when it was new.

Glad I had this experience even though it was frustrating and cost me some cash, because now I know a lot more than I did!

THANK YOU for all your help!
