Detecting moisture and abrasive contamination before damage occurs is a major benefit of engine oil analysis, but extreme temperatures in off-highway conditions can affect the lubrication as well. Testing examines viscosity and soot to see if the lubrication can protect the engine, if additives need to be added or if the sump needs to be drained.
Analyzing coolant takes the guesswork out of maintaining cooling systems. Test results can identify corrosion, contamination, improperly mixed additives and even stray electrical currents. Together, coolant and oil analysis offer the maximum protection for engines in off-highway equipment.
The biggest concern for gear systems is the type of wear occurring in the system, which is often caused by dirt and water. Regular testing designed specifically for gear systems will arm our analysts with the information they need to determine if metal particles in the lubricant are from normal wear or if they are warning signs of a catastrophic failure.
Off-highway hydraulic systems operate under demanding conditions. For the system to function properly over its expected lifecycle, hydraulic fluid must be free of contamination – and off-highway environments are full of potential contaminants. Water, particles and even air can contaminate hydraulic systems. Testing hydraulic fluids will check viscosity, fluid cleanliness (particle contamination) and water content.
