eSource 115 Proving the Value of Using Oil Analysis
The asset being sampled was the diesel engine from a Kobelco model SK260-10 excavator. The PLP and end user consulted with ALS regarding the elevated Lead levels flagged on the reports. Through proper use of oil analysis and data interpretation, an elevated trend in the bearing metals (Lead) enabled the end user to detect a deteriorating main bearing before it became a failure. The end user decided to take action based on the elevated Lead levels, and the actual total repair costs were:
Parts Cost: $500.00
Labor Costs: $440.00
Lowboy Rental: $1000.00
Fluids and Misc: $200.00
Total Repair Cost = $2140.00
Noted in the Annual Report, was that the end user recognized that without using oil analysis to detect this problem, the engine would have run until failure occurred due to main bearing wear. The resulting cost to the end user would have been:
Engine Cost: $27.000.00
Labor: $55.00/hour x 50 hours = $2750.00
Total Cost without Oil Analysis = $29,750.00
Total Cost Avoidance using Oil Analysis = $27,610.00 !
Looking at the sample history, there were six samples taken before the end user shut the engine down for repair. The cost per sample is ~ $20.00. So $27,610.00 on $120.00 is a very healthy Return on Investment! Every day we are saving our customers money, and proving the value of our service.
