Don't understand your question completely. I think if P1 your looking at is assembled properly you would find all helicals lined up on thresher side and all helicals on seperator side lined up. It could be some one has fliped the cage door which would allow helicals to be offset from one another. Seems to me if a guy did this the crop would be flowing along helical and then drop off a bit to pick up the next helical. If you installed the green stem kit in old P1 the steeper pitch thresher helicals would be lined up to the shallower pitch seperator helicals at three locations. This is a very nice looking setup especially if helicals are shimmed by at least 1_4". I haven't been around milo but think your right the P1s had better reputation than P3s. Gleaner has corrected this in parts as time went on. High wide wire rear half of thresher concave which allowed more seperation by preventing bridging of green material. P1s basically had no rear half of concave for they had about half the crossbars. Half the cross bars helped to prevent the green material from starting to roll. Another thing is the P3s have channel iron helicals (very good) but the first three on large machines dropped the material right back on the concave to mix the already once chewed green material onto the fresh material entering. You can see how that would overload left side of concave and cause some severe matting. Gleaner has made helical extention available to prevent the third helical from doing this and you can do more with installing steep pitch helicals in first couple positions. Sorry this is getting long but one more thing worthy of mentioning. P3s have a seperator grate which the P1s did not. Seperator grate can cause green material to roll which makes it dificult to seperate. Some guys in green milo have installed cage material covers over seperator grate to make a smoother surface for green material to flow accross. Gleaner have did a couple things to help correct this. One is they made the seperator grate adjustable so you could pull it up closer to cylinder. Two they offered the seperator grate in a high wide wire design which acted more like cage material. Some guys have removed seperator grate completely to install cage material replacement made by loewen. It's looking like normal seperator grate design will work fine in the green milo but you need something like rotor sweeps to prevent the rolling or mating. Aftermarket rotor guys can comment on there rotors for they fasten cylinder bars without tiping into flow which can help carry the green material threw without pressing tight onto cage! Hope I didn't make that to complicated. Have a good day.
