Primary cracks.. Run it?

[snopax]

Hey guys, see pic below. Noticed a number of hariline cracks in the primary close to the center hub. Is this ok to run?

mines the same, will be running it this weekend on grass

Personally I would consider that a time bomb that at the least
may leave you stranded somewhere.

appears a bit more severe than the normal casting flaws.

tick, tick, tick?

I have some on my 97 somewhat like that, I put it back on and kept riding. But that sled doesn't see the miles it used to anymore.

 

[snopax]

Think I can just san them out?

GUYS TICK TICK TICK IS A GREAT ANSWER. THESE ARE CAUSED BY HEAT. HIGH CLUTCH TEMPS. THEY WILL GET WORSE. AND KNOW THEY CAN,T BE SANDED. THEY ACTUALLY MIGHT TO START TO SHOW AT THE BACK. I HAVE SEEN THEM 1/2 UP SHEAVE. TIME FOR NEW CLUTCH BUD. 3:16 (yammie tony)

for what it costs it's not worth taking a chance. i had a comet grenade on my 95 vmax600 and i was very lucky i didn't loose any toes becasue a good size chunk came right out the left foot well. change it

Guess I'm in the market for a new primary then. Who's got one.

Why not just replace the bad sheave instead of a complete new clutch?

 

[YAMMIEGOD3:16]

YES SIR, I WOULD JUST REPLACE SHEAVE UNLESS THEIR ON BOTH SIDES. 3:16 (yammie tony)

 

[snopax]

Just one side, It's cheaper though just to buy a used clutch then it is a new sheave. Unless someone knows of some discount sheaves somewhere

 

[snopax]

What are the chances those are just casting marks. None of them are longer then 1/16 of an inch.

 

[A couple of bucks]

Heat Induced Stress Fractures. It's only a matter of time before it goes. Hopefully nobody is in the Line of Fire when it goes.

ZERO CHANCE. BUD, FORGET IT THAT SHEAVE JUNK. 3:16 (yammie tony)

 

[snopax]

Lol... Damn, was worth a shot. Following some leads on a sheave. Who does balancing?

 

[needaSRX]

Been running mine like that for 2 yrs

 

[sgauthier]

some do get them balanced, i've never toughed any clutches even after sheaves have been replaced or rebuilt.

 

[YAMMIEGOD3:16]

ANDY, NEVER SAID YOU CAN,T RUN IT. GO FOR IT LIKE YOU, BUT THERE IS A RISK OF THAT BLOWING APART. THOSE ARE CRACKS AND THEY WILL GET WORSE. 3:16 (yammie tony)

I know of two people that broke hands by the clutch exploding.If there are stress/heat cracks run it at your own risk but I advise not too.
