Combines Want to start the hypering process

If all you are doing is corn and soybeans I would start with the rotor, stacked helicals in the thresher end, F2 bars in the seperator belly and chaffer mods along with a 1 1_2 x 1" "wind board" at the back of the chaffer angled to catch those "bouncers". While you have the rotor out make sure the concave is level and every other wire is out to give you at least 1" spacing. If you have the old style concave with the mesh wire leave the first four rows alone as those concaves cannot handle the pressure (according to Hyper II). I had the old style in my N6 when I hypered my rotor and used a sawzall to remove every other wire. If you have the $$ the channel helicals and seperator grate really help but I would wait to see how well you like the rotor mods. You should notice a world of difference in capacity and sample quality. This is the beauty of these upgrades you can do them all at once or in stages like I did. It is neat to see how each upgrade improves the performance of the machine. I have done everything but the shocks and for my operation I really don't see the need. The great thing is you are not alone you have HyperII, tbran, NDDan and other here to guide you on your journey. Have fun! Pete Hinrichsen

Guess I never did answer you questions, got carried away in the spirit of "Hyperism". loewen has a kit for the feeder shocks. Removing the rotor is a fairly simple process as long as you have a good loader with a few chains for stability. I had to move the unloading auger out to remove the cylinder, I had the most room to get my loader bucket in when the auger was about 1_2 to 3_4 out. The first time is the hardest. FYI - I got used P3 stars, used flat helicals and a couple of forward bars from Worthington Ag Parts. I bought new helicals for the two extra rows you add. I had a machine shop make the bars to shim every other seperator bar and made sure they all weighed the same for balance. I made my own plates and gussets for the two extra discharge paddles and just bought the rubber paddles from AGCO. Hopes this helps, Pete

Thanks for the info PETE.It was your reply to one of my earlier posts that convinced me to get this N-5.It is an '84 with around 2000 hrs.Extremely clean and straight,always shedded but not used for the past 5 years.It was a nice improvement over the l2 but I would like to do the rotor this year. Thanks again for your help and be prepared for many more IJIJIJIJIJIJIJIJIJs

You are very welcome and I hope I speak for all of us on this board when I say that your questions are always welcome. There is only one dumb question and that is the one you are afraid to ask. Another little tip, if the diagram for the helical stack of the thresher end seems confusing take a copy of the diagram with you into the cage after you get the rotor out. It all made sense to me when I could match picture with actual. You may want to hone out the holes a little on the used helicals you will use to for the stack. This will make it a little easier to line up the bolt holes. Another thing, put you F2 rasp bars in BEFORE you reinstall the cylinder, they are a real pain to install after the cylinder is in. Also, once you have the rotor out, step back once and notice how compact the whole processor is from cylinder to cleaning shoe. With a compact processor you leave more room for a larger hopper. Sorry about being so long winded but there is no reason for you to make the same mistakes I did, I want you to make some new ones so we can all learn something new. Have fun, Pete Hinrichsen

You can fabricate your own feeder shock system if you want. loewen is only resource for the kits for older machines. I would get the rear kit for sure and then you can fabricate something for front if you want. The rear is the most important. When designing shock kits we desided to use shocks that were used on the front of Chevy vans for 10 or 20 years. These are the shocks the loewen uses. Shocks may not be needed if you are corn soybean only and run with drums locked up. Otherwise I would install shocks and let drum float maximum amount. What crops do you run or is corn in your rotationIJ Might make a difference to wheather or not you monkey with cylinder bar height or channel helicals as apposed shiming flat helicals.
