2002 SXViper secondary clutch cracked or casting?

[BrgrSXV]

Good day gents,

I purchased a 2002 sxviper last yr. and I removed the skid to have a few bushings replaced. while im at it, it was suggested to replace the LH drive/speedo br'g.
I removed the secondary and noticed 3 cracks. Is this from casting or cracks I personally believe its cracks but I need your input as im a newbie to this. pics attached Thanking you in advance

Castings flaw, sand them and they will go away.

DO NOT. I repeat..... DO NOT use it. I personally cannot believe it has held together w/ all of them. Shrapnel just waiting to explode!!!!
I'm willing to bet that alignment/offset is AFU as well. Lots of heat has been transferred into that secondary.

can we see a pic of the clutch faces?

I just noticed some casting marks that look like cracks on one of my primary clutches last night. They were casting marks upon closer inspection, but yours may be cracks.
Can you see through to the other side ? Do they transfer through?

You can clean them up and have them dye tested if you know any LPI or nondestructive tester.

They do look just like casting marks to me but I'm not there looking for myself I just see the pictures. In my opinion I would just leave it alone. My history with blown clutches are when you can look at the face of the clutch and see cracks. Thats when they become a time bomb!!!!

Those pics sure look spooky to me. Mine has some very light cracks in the casting but nowhere near what those pics look like. I would check it out very carefully, or have someone experienced do so, before running it.
