They were soooo stupid with the early CS-130 they glued a very fragile PLASTIC turbine fan onto the rear of the rotor. I chewed on the Delco CS project manager (Marion Hovermale) about it. The fan was changed to a simple stamped steel fin design which was cheaper and moved far more air. The exposed rear bearing was hidden in the soon to arrive CS-130-D model.
My bus Niehoff has exposed front and rear fans, and a cast iron frame. But both the regulator and rectifiers sucked so I fixed that.
It's these little quirky snatches of design insanity that reinforced by belief that I had made the right choice in not going corporate (and making 10 times the money). Design screwups are caused by in-house fiefdoms squabbling about incorporating signature designs that most of the time are ridiculously stupid. Hovermale emitted gagging noises on the telephone when I said those exact words to him.
