Combines main clutch shaft

I'm finding that in the 500 hour range (give or take) it gets noisy. You don't have to worry about it until it gets fairly noisy standing right next to machine. It only runs when separator is off. Your right that it is usually the inside one without orings. You best not use oring one to the inside for it will quickly wobble out the sheave. Gleaner started using wave washer next to bearing but it doesn't seem to do much. If it was a big enough problem or if it was hard enough to fix I would head to machine shop to have them turn it out to fit two bearings side by side. Maybe do the same for oring one if room but use the normal bearings instead. No reason to worry about bearing until it gets rather noisy standing next to it. Why don't you do the double bearing trick and report back in 60 hours. Thanks

We have had the same problem at 400-500hrs. We still use same agco bearings but pop off seal and add 2 more shots of lithium grease. We have had bearings with only assembley oil in them-last 2-3 days if much roading. Agco wanted date codes from bearing boxes. They had to recall over 50 bearings two years ago. Half of bearings in their bin in Batavia had same date code and were assembled with no grease. Do not over grease. We find 1_2 load to be sufficient and have bearings still in at 750-800hrs. We like to pull mainshaft at anything over 800 hours as part of our maintainence program.
