Hello there,
had a clacking found on my Vario, i had a Yamaha Grizzly 550,so i disassembled the Vario from my Grizzly, but i found nothing.
But the shaft where the primary Vario puts on, wiggle, I can move it to
difference ways, up down, left or right.
So, i removed the clutch Housing , and have found that i can wave the clutch shaft a little to differnt ways,up,down,left ,right.
There are 6 Bolts, all 6 Bolts seems to be a little loose.

Now I do not know, if that ,has to be from the Factory or if it's a
Malfunction.

Is this normal with the 6 Bolts or not ?

Please Help Me !!!

Thanks

Welcome from Colorado.
Those are pressed rivets and not supposed to be loose.
I think I know your concern, but a video will help us know for sure.
If the shaft is not tight to the drum, replace it.

No idea other then replace it (that's pressed on by the factory). But that puppy sure has some play in it. Ridgway have you seen or heard of this before or is it something new?

This is the first time seeing this for me. Its fortunate it didn't come apart while turning. One of those rivets in the engine could have caused a complete failure. That probably didn't happen because of the bearing at each end of the shaft and the sound caused the O.P. to inspect quickly.
As for a quick/easy fix, bolts will not work. That is the reason for the rivets. Plus all the holes are elongated. And I wouldn't consider welding or epoxy either.

You could take it to a good machine shop have the holes drilled to the next size rivet and have them re-rivet it.
However it would probably would cost more than a new clutch housing.

I would also recommend replacing the bearing in the cage support as it could be a cause.

As a machinist I can tell you about anything can be fixed, but getting the two pieces concentric & getting the runout within a reasonable amount would be tricky because like mentioned before the holes are elongated. Welding would have a chance of warping it. A quick search tells me it's around $170, like reogem said your better of buying new. There's a good chance it was getting worn anyway. Hope this helps and good luck. Dont forget to stop back in and let us know how it worked out.

If it were mine Id just try with air hammer and tighten uprivots if the $170 isn't in the cards now.
Isn't that bad ... Yet

In 2012 the snap ring was eliminated
The part # for older clutch housing is 99999-04069-00

The newer # is 99999-04070-00

Old 2012 part #3B4-16611-01-00 no clip groove
Old 2011 part #3B4-16611-00-00 has a clip groove
Now they have the same #9999-04070-00 doesn't have a clip groove

The bearing # on both is the same.
I'm guessing that Yamaha decided the the clip wasn't needed.
