Larry,

Thanks. The pins holding the rollers would hit each other at one point in the rotation. Slight bending was all it took to correct.  I notice that the one roller does not roll it is worn and rides flat. I figure I can break the roller up and carefully remove all pieces then I could snip the pin and install new roller and pin. How difficult is it to crimp the new pin so that it won't fall out?  It appears to be like a rivet. I would think this could be done with the arms in place and not removing any parts. Please advise.
