I'm installing S&S 583 cams in my 2012 FLSTC Heritage Classic. I watched the installation vid that's on the S&S web site, and it's a little bit different than what the instructions (came with the cam kit) spell out. There is a step that calls for measuring the clearance between rear cam lobe and the pinion bearing boss, and if necessary removing enough 'material' to allow for a .030" clearance. Has anyone had to shave down the boss, and if so what did you use to do that? I'm thinking that Dremel ought to do it, but was hoping someone here might have some insight. I also saw that the oil pump screws need to be removed, and that the guts of the oil pump stay in the cam chest, and the oil pump housing is integral to the cam plate. I'm not doing anything with the pump so I don't expect any problems. Anything to watch for here? Thanks all!
