Combines 8560 rear spindles

Our 760 came to us fitted with oversize steer tyres and we collapsed wheel bearings regularly (20 to 50 hours max) on the drivers side (outside on turns). I had previously owned massey tractors that did that and was convinced that from 1960 to 1980 Massey had an IDIOT designing the steer assemblies for their equipment - we fixed the tractors by boring out the hubs and fitting bigger, heavier rated bearings, the 760 went back to original sized rubber and seems ok but is a POORlY ENGINEERED setup. My conclusion is if you run hard or fit oversize tyres you will have problems because the original engineering is marginal for most machines (including green ones)

Yup!!The engineer must have not had too many working brain cells ,I've lost track of how many times I fixed smashed hubs on our 860. I started repacking the bearings every year that seems to help a bit.
