That may have been due to the cam material instead of the bearings. I have seen it happen in automobiles, too.
I also saw a thread in the AIM magazine forum that is excellent on replacing the cam, shoes, etc. It has great pictures and some real world experience added in. The thing that shocked me was the difference between the bearings that Harley uses and Torrington bearings, the ones that everyone says you should be using instead of Harley. They cost like $15... and Harley keeps using the INA ones... man... now THAT's a big deal.
Your shoes looked pretty good to me... you could have probably gone 70k without much trouble if it wasn't for the cam! Unbelievable. Which oil have you been using?

Oh Yeah! I just changed out the cam brg. on my 99 EVO at 27,000. It still looked great along with the cam, but I put in a new Torrington for peace of mind. Also put in adjustable pushrods in case I want to change out the cam and lifters at a later date, and it made it really easy to do the brg.

But from 16K till now in the past 3 years, I put Syn3 and at the 3.5-4K Mile mark as our weather in Toronto is considered 'Extreme' and Donny (Petereson) urges extreme weather riders to shorten the interval.

The cam journal runs on the bearings, not a race... but I haven't had one of the torringtons in my hands to notice how, or if, the roller pins are held in.
Ujoints have been done this way forever... I suppose it has to do with space available.
I haven't done this work, yet, on my Harley so my opinion remains cloudy... I'm just reporting what others have noted and what I have actually experienced on another manufacturer's bike and cars. To be fair, you can't help but get a bad casting from time to time when you make a couple hundred thousand cams.
It's what you do after the problem is discovered, warranty period or not, when it clearly isn't any other issue at fault but a defect... that's what counts. If everything looks great inside that engine but the cam and it only has 16k on it, it doesn't take Sherlock Holmes to figure it out.

Thanks for the Info man,
I doubt HD will have anything to do with those, at any rate, I was going to change those suckers any ways, but man , if the s..t hit the fan on my Engine, I would have been royally pissed.
