Questions about engine internals ...
I'm making a CAD model of a 60 degree v-twin air cooled engine. I have never taken apart an engine, and I don't have one sitting here that I can take apart and measure, so I'm making this up as I go.
In a Corvette, how is the top of the pushrod connected to the rocker arm? Okay, maybe "connected" is the wrong word, but what is the geometry of the top of the pushrod that contacts the rocker, and what is the geometry of the rocker to accept the pushrod? Is this just a "ball" connection?
And, is the bottom of the pushrod hard fastened to the lifter, or does the valve spring keep them connected?
Thanks for any help.
