I have attached the latest oil sample report for my excavator, a Cat 311B 8HR00401. An oil sample was completed when I bought the machine, most of the fluids indicated extended service intervals, etc. As suggested I completed a second oil analysis after 100 hrs, that report is attached. Overall, all of the samples showed improvement. The one that I’m curious about, and would like opinions on, are the two final drives. One final drive shows normal wear metal counts and particle counts. The other is still showing elevated wear metal in the sample. What, if any, action should I take for this specific final drive at this time? Thanks!
