The last couple of TY 4s I.ve built all have had a problem with the thrust cam Bearing. The side with the shoulders is always too tight. The cam will not spin freely . The other side , without the shoulders spins free. I 've tried three different brands and they have the same problem . The used ones have the gray finish warn but they spin fine. AL

What cam are you running? As you know anything NOT spinning freely is never a good thing. I would be somewhat hesitant sanding the shoulders of the new cam bearings, but also not sure where else to go. Let us know of your results
