I find this cracking in the crankcase behind the hub:



Thoughts, opinions, smart-*** remarks....

 

No wise cracks (no pun intended ) to be made here .....that's potentially disastrous

Maybe take it to good metal fab shop with a TIG and have them grind into the cracks and
tig it back up .....see if it'll stop further progression & hold

Seems a fair bit of sag around the bearing though.....& that may well be the culprit
shaft slapping from 8 oclock to 2oclock.

That bearing needs to come out too ..........must check the manual see how it's all setup

Is that a chip of the casing missing at 3 oclock ? Damn .....don' want to tell ya what ya don't
need to hear .....this would ruin my Sat morning

So ya got try and figure ......what made the bearing bite the dust

 

Everything is actually fine, bearing spins with no notching. I'm just replacing the basket because the teeth are worn enough to make me hear it at idle ( and I had a spare basket kicking around)

 

Cool....... Guess I'm just the paranoid type relative to stress cracks like that

 

I'm inclined to go with Sprock said.
It would be worthwhile to at least take a magnifying glass to those cracks (there seem to be a number of them radiating away from the primary shaft)
Fortunately it's not major surgery to remove the clutch now and again, so keeping an eye on it is what I'd do.

If you guys think that's bad, you should see my camshaft holder caps

 

Mal' ...................man my guess is you suffer from some seriously unknown wrist twisting ailment

 

Not as much as I used to. My local constabulary has seen to that.












Or I'm getting old.

 

Spray it with crack dye and show us. I would like to see where they part so i can check mine. That looks like cast marks?

 

1) I would need a new nut and cover gasket as I've already put it back together and ridden it

2) Need to order this Crack Dye stuff as nobody in my ****hole area would know what it was

3) Need to bug my father again to hold the clutch basket while I torque the nut down
