-those numbers are gaskets on turbocharger oil lines, 4F6109 + 4M6480, where it connects to oil supply, and one where it returns to engine block
-book says "gasket"
-o-ring in drain tube is 9H6067, correct
Hi Team,
just as an aside to get closer or more accurate assistance.
In this era Cat used Engine Serial Numbers and Arrangement Numbers to complicate matters as some engines have Sleeve metering Injection Pumps and others had the usual Scroll Injection Pumps. This altered the turbo oil lines and other components.
I do have a 69J2539-up D6C P/Book with the 44V1-up Engine range.
In the Parts Book the Engine Arrangement Numbers (like 2P6795 or 4N7365) allow one to zero in on the actual Group Number of the parts used to make up the engine arrangement--this explains why Kittylover123 was somewhat vague about some part numbers.
This is complicated for the average person but gets one the actual parts used and not a guess at what may be used.
Cheers,
Eddie B.
