When it comes to the care and maintenance of your new, used, or rental heavy equipment, it’s important to invest in regular maintenance and to invest in preventative maintenance as well. Technology plays a vital role since it can be used to gauge the health of your machinery to tell you about how your maintenance plan is doing and what needs more attention or less.

Part of effective machine maintenance is Scheduled Oil Sampling (SOS) and Fluids Analysis — for oil and coolant.

Regular fluids analysis is the analysis of your Cat machine engine’s oil, as well as the fluids from other components, like hydraulics, transmission, final drive and cooling systems. It offers a clear picture of the inner workings of your machinery. Fluids analysis works by taking a sample of oil, coolant, and fuel mixtures that are then tested for any contaminants present, such as metals or other debris. The data is recorded and then used to help discover where minor leaks and wear and tear could be lurking. This can help you repair these areas of your heavy equipment before they become problems down the road.

  • Total Base Number (TBN) — This test tells you the level of alkaline additives in your machinery’s oil. Additives are necessary in machinery to help prevent the component parts from wearing down prematurely. However, additives are used up as your equipment runs, which helps to make them ineffective, especially during the combustion process.
  • Total Acid Number (TAN) — This test tells you the level of the acids in your machinery’s oil. It is desired that the TBN be higher than the TAN number.
  • Oil Viscosity — Viscosity is the thickness of a substance, which tells you how quickly it flows. In general, the higher the viscosity, the better heavy equipment and machinery is able to handle temperature extremes and pressure changes.
  • Coolant Chemical Balance — This test makes sure the coolants in your heavy equipment are at a healthy level. They test the glycol and pH levels, which can tell performance and other metrics.
