Pilot Bearing ?
I have not seen a magnum crank that wont accept a pilot since I pulled the first one in 95. I have pulled a few a month, at least, since then to give you an idea how many I have taken apart. Pretty safe to assume 0 out of hundreds means you are safe. Pulled 3 last week. Say 24/year x 20 years is 480 but probably more. I bet a 6 pack you are safe.
