• Initial Wear: New components experience faster wear during the break-in period due to rough friction surfaces and uneven contact pressure.
• Lubrication: Tight clearances in new assemblies can affect lubrication effectiveness until proper wear patterns develop.
• Fastener Loosening: Heat, vibration, and initial wear may cause fasteners to loosen during early operation.
• Potential Leaks: Seals and couplings may develop minor leaks during the initial operating period.
• Operator Familiarization: Proper training is essential to avoid operational errors during the initial use period.
