Was looking over machines today and noticed on the 2588 that the concave hanger support plate (the concaves bolt to it on the left side) is not parallel to the angle iron that forms the bottom of the top of the cage. How's that for a complicated sentence?!! Anyhow, its nearly 1/2" lower on the front than the rear. I'm thinking that it should be parallel otherwise the concaves aren't parallel to the rotor. Yes or no?
