Hie all I just stripped down the engine on my uno 1100 fire and noticed one big end bearing was chipped on the crankshaft side. This engine was running perfectly but I felt like it was time to overhaul it. My problem is the big end bearings are labelled 7596773 B520 3A and the other side its written fiat TR 20 fm-69. What size are these big-end bearings are they standard or what. Any suggestion will be greatly appreciated thanx alot
