Combines Steep pitched heilcals

This is what we do. Remove helical 1,2,and 3. Cut off 6" off the back or rear of the first helical and reinstall in origional location. This leaves room to install the steep pitch approx one hole to the left of where this one was located. Then loosly install the first steep pitch helical to line up with the helical extention (triangle extention over the upper lH infeed area part n 71402029) with a couple of bolts. locate with marker or paint pen the postion to drill or blow 2 new holes in the solid plate to locate this first helical. Then remove helical, make the holes (do not try to blow a hole through the hole in the helical, this will weaken it and it will fail - trust us on this) reinstall n1. These are the only holes you will have to make. Install steep pitch in location n2. Install short helical in position n3. Where the helicals intersect the standard pitch, either cut the std bars orogionally in the machine and remove the back part and discard it, or mark them , remove, cut and then reinstall. What one now has is two long part n 71373494 long helicals and one 71373495 short one that transitions itself into the regular pitched bars.

We normally removed 1st original helical if starting right at gearbox wall with steep pitch but no problem leaving what you have room for in there like tbran explains. If you want more complete steep pitch on thresher side than tbran explains than start another or third long steep pitch where original third bar started. Same thing on fourth then install the short steep pitch. If you wanted to continue into seperator side you could skip the short bar and keep up same pattern and spacing as far as you want. We have setup milder case of steep pitch and setup steep pitch all the way threw but four long and one short makes thresher side look very good. Might want to shim steep helicals by 1_8" or so and protrude shim toward pressure side (seems to me that is a trick from down under on the old P1s). I might be able to find a picture of one setup or another if you would like. Good luck
