OK, M0081390 only applies to on-highway truck engines as far as I can see. At a quick glance I can't see the S/N prefix of a C7 engine for a 140M grader.
One thing in the document that IS relevant though, is the comment "Perform the procedure in Special Instructions, REHS3819 and for repeated low hour failures review Special Instructions, M0068178.".
Taking M0068178 first. This document DOES apply to 140M and requires checking the oil filter base gasket, cooler flange flatness, & the bypass valve amongst others.
REHS3819 again is relevant to a 140M and details the procedure to clean the rail. I think the words "After a HEUI Pump Failure" should be included at the end of the title.
So in summary, M0081390 is only relevant to a 140M in as much as it makes reference at Step 1 of the installation procedure to two other publications that are relevant regarding problem areas and cleanout procedures to be performed after a HEUI pump failure. I would tend to agree with the Cat guy about not installing the inline filter on this particular engine because it is not mentioned in the list of products just below the title of M0081390. The only use I would make of M0081390 is as a reference document directing me to procedures to be adopted in the engine regarding potential trouble spots (M0068178) and also the procedsure to follow for cleaning out the rail after a HEUI Pump failure (REHS3819).
