Are the setscrews needed?
Can I drill a hole in the pillow block to tighten them?
Or Are you supposed to take the rotor drive sheave off and slide the shaft through enough to get at them?

If your talking about the big bearing on the main clutch shaft, don't use the set screws. the long shoulder with the set screws on the bearing goes towards the middle of the combine. What holds everything tight is the bolt on the end of the shaft. Make sure you get that bolt tight or the bearing will spin on the shaft. Also make sure the nut on the RH side is torqed to at least 600 ft. lbs., it will also spin the bearing on the shaft.
