Not to Hijack RRR thread but what pulley are you talking about? I have the factory 66’ pump on my 273 with the factory pulley and cast iron water pump . The lines Bergman sells screwed directly to the pump and box and honestly my steering work great. No troubles or belt slip. Not tough to steer or too easy either. Federal style with a (approx) 4.5” pulley is what I have. I see the trw styles have the what looks like a 6” pulley.
