Combines Feeder Shaft Breakage

Started wondering the same thing. We have a '98 R62 with about 1000 engine hours. The rear feed conveyer shaft snapped on ours yesterday. Drive pulley broke off just outside of bearing. The bearings seemed fine. Could'nt find an allen wrench to fit set screws in sprokets and had to make our own. Big job for non mechically inclined farmers.

these shaft breakages are as much a puzzel to the guys at the plant as it is to us. They have been in an all out quality control and reengineering mode to radius the machine areas and other things to fix this randon problem. Seems like some machines never have a problem and others got all the bad shafts IFthat is what is happening. Contact you local dealer and ask him to call area service rep and ask for help on a policy adjustment to cover the shaft. Might get some help.

I had a 92mod R-62 replaced both shafts with a much heavier shaft at that time Gleaner went from the set screws in the sprockets to a 3_8 bolt that kept the sprockets from moving. I now have a 98mod and was assuming that it also had the larger shaft. Maybe I assumed wrong. Good luck

We also broke a shaft hear and there. The biggest problem was machinest left square corner in an area that can flex. Just like a crankshaft if a machinest cuts it and leaves a square corner it will likely break someday. Any of these shafts from Gleaner now should have radius instead of sharp corners. They also changed a hardening process which should help. It think we broke more shafts when they went with the larger hex portion of shaft which makes me think the machineing has more to do with it than anything.
