new to us cat vib roller 3 years ago,had a noise like drive motor on the way out. 3yrs later it was really noisey [ traffic controllers put on ear muffs if we worked close to them ] pulled apart the oth er day and the pics tell the story. cat mechanic has never seen a bearing do this
What took so long to check it out?
didnt make metal ,owner hardly ever seen it working, we would complain about the noise but out of sight out of mind
