Got it,thanks. I looked up the 4 obsolete liners online for my serial. The part numbers they kept coming back as 150 mm Non APR with pink o-ring, so I was wondering what it means

That’s very poor from Cummins. I always wondered why I’ve heard of so many spun bearings with these motors

Spun bearings are not the red engine makers fault.. its the idiots who are improperly trained on this info and don't pay attention when rebuilding them.

That information is nothing new at all. I have been around these red engines for more than 15+ years .. and I heard about checking these things early on... and have since, seen plenty of engines with alt-size parts in them, right from the red engine maker, as they came apart for the first time.
