Combines How to level concave

under all cylinders there is a stationary threshing bar or concave. It is important that the distance from the cylinder bars to the grate or concave be the same all across the bar. Each machine has the instructions on how to level the cylinder or concave in detail. Which machine are you refering to in this question.

I have an early N-6. Thank in advance.

does your machine have the cables (hopefully not) or the cams. IF you will email me with a fax n I will fax you the instructions and picture.
