So I'm rebuilding the engine and need to know what the original bearings in the engine are. We've measured for wear and are good to replace with what is currently in there, problem is Jag uses colors for ordering replacement bearings and all I can find is what's stamped on the bearings and engine. Can someone tell me what the markings correspond to in terms of colors. As you can see they're all marked STD. Thanks!

Engine Markings 1/3
Engine Markings 2/3
Main Bearings
Big End Bearings
Engine Markings 3/3

 

This extract from the X350 Workshop Manual may help explain the coding and bearing colour selection:

You didn't mention Model Year or engine size so I've had to make some assumptions.

Thank you Graham! Totally forgot to look at the workshop manual.
