If you are not running your engine at recommended operating temperatures one hundred percent of the time, you are bound to have some level of wet stacking occur. Diesel generators usually run at suboptimal temperatures when they don’t have at least a 60% load while in use; this means the engine never reaches the temperature level needed to burn off the excess fuel and carbon deposits, which leads to build-up in the exhaust system known as “wet stacking”. How Do I Know It’s [&hellip;]

Changes in the vibration patterns of your motor are one of the first indicators that your motor may be heading toward a critical failure. Vibration analysis experts estimate that by the time your motor starts making audible noise, your motor is only 1-4 weeks away from a critical failure, whereas a slight change in vibration patterns, invisible to the naked eye or ear, starts about 1-9 months before the same critical failure would occur. These early issues are hard to catch and correct without using vibration analysis as a predictive maintenance tool. Vibration analysis includes the [&hellip;]
