I wanted to follow up and say thank you for the help from those answering my questions about shear bolt bushings and worn PTO shafts on my NH 273 baler. It took some fabrication to get everything back together...
The flywheel and associated bushings were all substantially worn. When I went in to replace the bushings on the slip clutch I found that the clutch pilot was worn out and BENT which I'm sure contributed to my PTO shaft flopping around... Took a 4hr round trip to get a used replacement pilot instead of paying $340 for a new one.
Went to drill out the shear bolt lever arm in order to put a drill bushing in. It turned out to be hardened. I had to order a carbide drill bit in order to get through...
The PTO shaft I ordered didn't fit (wrong U-joint series). Bought all the parts and pieces locally and had to cut them down, re-weld and assemble.
After all this ordeal and several dollars later, she runs smooth as silk! I never knew it was supposed to be this quiet. No broken shear bolts, no missed knots and very quiet around turns. I made the first couple laps with it and a couple times I thought a shear bolt went since it was so quiet! After that, I was able to convince my better half to drive. This was her first time REALLY driving a tractor.
