This is probably the most common mistake when a shear bolt breaks that leads to a destroyed baler-not understanding why the shear bolt broke in the first place.
Thank U for your time to make the shear bolt post today, hopefully the ppl baling that need to see this will & listen to what U mention sinks in. Happy baling my friend!
This is a good one. Last year I had snapped a bolt, replaced it, thought it was packed feed like the last couple times, cleared the feed out and WHAM broke another bolt. Second bolt in and I found the stop for the needles was out. I then discovered the knotter shear bolt had gone. So I got it replaced and turned it over by hand, yet it was still striking the needle stop. I brought it back to the garage and eventually found that one knotter had dropped. The bolt had somehow gone bye bye that held it in place. Luckily it was on a friday and the nearest NH dealer had the correct parts for it and was able to pick them up Saturday morn. A new shear pin for the gear, and new pins with clips for the knotters instead of bolts, and retimed it all. Ran the rest of the season without a hickup. Just need to replace a couple chute wedges for tighter bales and this NH273 that is older than my wife can continue making good bales.
I always get the flywheel shear bolt to break because of the jam built up, but everytime i see the alfalfa i dont think its too much inside the baler. Maybe because its a little wet ?
My new to me 08 575 gave me hell this weekend. Finally got it to make knots after several missed bales. Then we snapped a shear bolt - I think it was too much material that caused it combined with weak shear bolts.
