Oil Sampling

Routine oil sampling predicts component failure
Analyzes metal content of oil from compartments

Why sample oil?
Analyzing an oil sample tells you what's working properly and what may need repair in your machine. An oil analysis for your machine results of the oil analysis tell you what's right and what's wrong with your machine—just like the results of the blood test tell you what's right and what's wrong with your body.

  • Avoid unplanned downtime
  • Increase component life
  • Increase safety during machine operation
  • Reduce costs for equipment parts and service

KOWA is Komatsu's oil sampling system. Analyze your oil
regularly to help predict what could go wrong in the future.

  1. Purchase a KOWA Kit
    KOWA Kits are available from any C.N. Wood location. The kit includes everything you need to extract your oil—plastic containers, pump, plastic tube, instructions, field sample report form and a prepaid mailing envelope. The cost of the oil analysis is also included in the purchase price of the kit.
  2. Submit Oil Samples for Oil Analyses
    An independent laboratory conducts two types of tests on the oil samples—physical and spectrochemical. Physical analyses measure the physical characteristics of the oil, including viscosity, fuel dilution, oxidation and nitration, and concentrations of water, glycol and fuel soot. Spectrochemical analyses identify and measure 21 specific elements, including iron, copper, aluminum and silicon, which may otherwise be undetectable.
  3. Review Test Results to Assess Machine Performance
    Precise, easy to understand reports are provided by fax, through the mail or on an electronic bulletin board system over the Internet. Through these reports, the wear and per formance conditions can be assessed for internal, oil-wetted components such as engines, transmissions and hydraulic systems.
  4. Review Maintenance Recommendations with your PSSR
    The detailed reports also include maintenance recommendations, which are produced from an equipment trends tracking program, so that you can schedule maintenance well in advance. C.N. Wood's PSSRs can help translate the results into maintenance strategies.
  5. Access Historical Data
    Komatsu has a data management system that stores the results of the oil analyses, called Lube Oil Analysis Management System (LOAMS). Historical data is stored online where graphs, reports and comprehensive recommendations can be accessed.
