This is fact. Up until I left the engine group the Trenton engine plant installed “green” cam bearings then machined them all at one time.
Green means “not finished to final size”.

The Kokomo Trans Plant did the same thing with all auto transmissions. Pump/converter bushing all the way back to the output shaft bushing and everything in between.


Were the cam bearings “bored” in place one at a time, or was the process more like one long tool with 5 different sizes, and all 5 bearings cut simultaneously?
