Crankshaft Specs E-7 350

[Paulieflyer2]

I am trying to find the crankshaft specs for my 1991 E-7 350 Mack says the rod journals are suppose to be at 3.248 mine are at 3.332 with std. bearings,I plastigaged the new bearings at .003 to .004 "what am I missing here" this is about .015 diffrence it's been running like this for over 200,000 miles the Motor was remaned by Mack the new bearings have the same numbers as the old ones,I had a machine shop come out to measure the crankshaft

This is from the E7 Manual. I've seen instances when the manual didn't have the correct measurements listed. Assemble the rod, bearings, and cap and measure the bearing ID with an inside micrometer or a "snap" gauge and outside micrometer and compare to your measurement for the crankpin to verify that you have correct running clearances.
