II. Model Breakdown
• ME: Indicates the product series, specifically Eaton's Dowmax ME Series.
• 175-4100: Represents the displacement range, typically measured incm³/rev (cubic centimeters per revolution)ormL/rev (milliliters per revolution). This range signifies that the series includes multiple displacement specifications to meet diverse application requirements. For example, ME175 may refer to a model with a displacement of 175 cm³/rev, while ME4100 denotes a displacement of 4100 cm³/rev.
