Hi guys . Could be a stupid question but here goes . How tight should the fan belt be? I have a 41 flathead and I hear differing options on how tight the belt should be. Too tight and the generator could get damaged . My gen has been re built and new water pumps and a new belt was put on about 6 months ago. At higher RPMs the gen makes a noise like a rusty machine type thing, at idle not a lot of noise but some . I have the correct belt. I took it to the re builder to check it out and he said that there is wear on the narrow part of the pulley ,he put it on his machine and said it was fine. He will pull it apart to make sure it’s all good .. but have I had this belt on too tight , how loose should it be? Thanks guys
