It's been an interesting year this year with the tough conditions around here. (Yorkton, Sask., Canada) Well let's see problems.... We broke 1 stud bolt on the flex plate on the upper shoe shaker drive on the self levelling sieve on our 97 TX66 (600 hr). Kept looking and found one back Idler arm pivot for the top sieve broken, there was an updated and heavier arm to replace it. Torque sensor performance was getting bad, but we removed, cleaned and repacked it with grease and installed a new belt. The most mysterious breakdown we had was the biggest one. The primnary countershaft which is driven by your main thresher clucht belt and basically drives the entire separator broke. It broke about 1 inch in, from the outside of the separotor_feederhouse clutch pulley. The cleaning shoe, fan, returns are all driven on a pulley at the end of this shaft(this broke off, and fortunately never fell into the fan causing further damage). Still no answers why that broke. Been having trouble with the Autofloat on our 971 header. Have US sensors, new skid plates for the sensors to read off, and installed orifices in the lateral float lines, but the system is still too "bouncy" and it seems to be in the lateral float, you can notice it when you tilt it manually as well. It's like the accumulators are overcharged.(or not properly setIJ) Hope this information might be useful, any questions, suggestions would be greatly appreciated
