Attachment_4_Correct_MTU_8V2000_M72_Maintenence_schedule_0001.pdf

This is a technical documentation and maintenance schedule for the MTU V2000 M72 diesel engine in Application Group 1B. The document provides comprehensive maintenance requirements across four operating hour ranges: 0–5,250 hours, 5,500–10,750 hours, 11,000–12,000 hours, and beyond, with maintenance intervals specified in weeks (w), months (m), and years (a).

The maintenance schedule matrix identifies specific tasks and their required intervals, including routine operations and inspections (daily engine oil level checks, visual inspections, and leak detection); fuel system servicing (fuel servicing plant checks, fuel filter replacement); crankcase maintenance (breather cleaning and filter replacement at 250 and 500-hour intervals); and component-specific services (centrifugal oil filter, valve gear, belt drive, coolant filters, and air filters). Advanced maintenance tasks are scheduled at higher operating hour thresholds, including fuel injector replacement (6,000 hours), combustion chamber inspection (6,000 hours), component maintenance requiring coolant system drainage (6,000 hours), turbocharger overhaul (6,000 hours, qualification level QL3), cylinder head overhaul (12,000 hours, QL3), and extended component maintenance including complete engine disassembly and inspection (12,000 hours, QL4). Each maintenance task is assigned a specific work task identifier (W-code) for tracking and documentation purposes. The schedule ensures systematic maintenance to preserve engine performance and reliability across the engine's operational lifespan.
