Cracks in Secondary Sheave

[apex55]

While servicing my secondary I noticed quite a few cracks in it. 06 Apex er w/14k on it. Is this normal?

Those are just casting marks, not cracks. There is nothing wrong with those, clean ‘em up and run them.

Yep...your fine , not cracks.

Casting marks, if it was cracked with the tension of the spring you would see it
