Observe the step-by-step operation and see practical examples of usage. In this video, we demonstrate the installation and function of the 9Y-2988, 361-1716, and 365-5169 excavator crankcase breather, compatible with E324D, E325D, and E329D models with C7 engines. Watch how this component balances crankcase pressure, separates oil mist from blow-by gases, and reduces oil consumption in demanding work environments. Learn how it prevents oil leakage and contamination while resolving common issues like excessive crankcase pressure and oil burning.
