I am new the Gleaner rotaries and I am trying to level the concave. The machine is a 84 n6 serial 7450. The operators manual refers to loosening cap screws before moving the concave more than 1/4". Where are the cap screws located? When leveling the concave should the rear Eye bolts be adjusted to zero and left at zero or should the be set at the recommended crop setting? When reading the concave indicator how far does each mark indicate?
Thanks in advance with any help.

I leveled mine a few years ago. It was set so there was no wedge(tighter at the back than the front) so I used feeler gauge and adjusted rear to be level with a rotor bar. For the front there is a eccentric ring to adjust front of concave for level side to side. I think the bolts they want you to loosen are the ones that bolt the concave to the adjuster. The marks are a approximately 1/4" of concave clearance.
