    In the article, the method of early diagnostics of nascent defects of mechanical assemblies (friction nodes, bearing pairs, gears) is considered by on-line determination of high-order statistical moments of the vibro-acoustic signal. To determine such statistical moments, a parabolic spline approximation of the discrete signal values is used.

    After measuring all eight rod bearing clearances and using shell halves to set the clearances, it’s very common to have a clearance spread between the rods of perhaps 0.0004- to 0.0005-inch. Let’s say our loosest rod bearing measured 0.0028-inch while the tightest rod came in at 0.0023-inch – creating a spread of 0.0005-inch.
