I got a call this morning from a guy with a broken tractor part . This is a clutch hub for a PTO , hydraulic actuatuion . The problem is that something else broke and the clutch over-pressurized like 12X normal . The pressure blew the lip (picture a sleeve about 2" OD with a groove around one end) that retains the o-ring right off the hub ! The fix was to build back the lost material with the TIG and some ER70S2 mild steel rod then machine it back to spec . The only snag in the project was getting a bushing out before I built it back up , trashed the original and had to machine a new one . I had a great day , stretched my skills and made some money to boot .
