Why Dispersancy Is Crucial for Engine Oils Coolant contamination, overextended oil drains, water contamination, high blow-by, long idling, high elevation and exhaust gas recirculation can all result in the loss of dispersancy in motor oils. is loss can cause engine deposits, sludge, impaired lubrication and oil flow. ML Quit Replacing Oil Seals If you are constantly changing gearbox oil seals, check the gearbox breather for plugging. When breathers become clogged, internal gearbox pressure can build and find its way out through oil seals, creating a false impression that the seal has failed. is can become more problematic during summer months. Paper Thermometer Can Reveal Temperature Spikes In time-critical situations where real-time infrared thermography is impractical and thermocouple/recording equipment cannot be installed, consider temperature-sensitive tapes. ese tapes are manufactured in a variety of sensing ranges and will clearly record the peak temperature that a machine area reached since the tape was first applied. A quick visual check is all it takes to read the "paper thermometer." Try Oil Mist for Better Contamination Control In bearing applications where high contamination levels are a concern, consider converting grease lubrica- tion systems to oil mist lubrication. Oil mist systems are slightly pressurized, helping to exclude contaminants. Use a pure mist system for rolling-element bearings and purge mist for gearboxes and journal bearings. Have Some Tips?
