[QUOTE="bitwrx, post: 8152778, member: 86972"] This is what happens when you let stock farmers operate machinery [ATTACH type="full"]1038112[/ATTACH] It's the drive end of a Kuhn topper flail shaft. The narrow bit is where the bearing used to be before it exploded. As you can see, the failure was not noticed immediately. Or even very soon afterwards. This is the side plate onto which the bearing was mounted [ATTACH type="full"]1038113[/ATTACH] The hole in the middle should be round. :facepalm: :cry: Quick application of some Pickhill Bantam, and a little Makita, got us to here: [ATTACH type="full"]1038114[/ATTACH] So far, so bodgey. But I thought I'd try my hand at being a proper old fashioned fitter. Say hello to my little friends: barsteward, second and smooth. [ATTACH type="full"]1038115[/ATTACH] At 14 inches, they're not all that little though. [ATTACH type="full"]1038116[/ATTACH] Some time later.... [ATTACH type="full"]1038117[/ATTACH] There are some hollow bits where I didn't lay down enough weld, but I think it should be alright. It's a spherical bearing, so the shaft is not subject to any bending stress at that point, just the torsion from the belt drives. Fatigue may kill it eventually, but the machine is already 25 yrs old, so I expect something else will kill it first. The bearing is a good sliding fit. Engineer's blue reveals the odd high spot, but it's surprisingly round. All together, I'm chuffed to bits with the repair. Tomorrow's job is to get it all back together! [/QUOTE]
