You plan to implement lubricant monitoring at your facility using a contract laboratory. You plan to include all gearboxes for several surface grinders in the pilot lubricant monitoring program. You expect the lubricants to show contamination from metal wear particles, grinding wheel material, and water-based coolants. Additive breakdown will also need to be tracked. Monitoring services can be obtained from TestOil, Insight Services, and/or Oil Analyzers, Incorporated.

1. At what locations should the fluid samples typically be collected? Explain.
2. Which lubricant monitoring tests should be considered? (Identify at least three) Why?
