4.1 Preface
MTU maintenance concept
The maintenance system for MTU products is based on a preventive maintenance concept. Preventive
maintenance facilitates advance planning and ensures a high degree of equipment availability.
The maintenance schedule is based on the load profile/load factor specified below. The time intervals at
which the maintenance work is to be carried out and the relevant checks and tasks involved are average
values based on operational experience and are therefore to be regarded as guidelines only. Specific
operating conditions and technical requirements may require additional maintenance operations and/or
modifications of the maintenance intervals. In order to be authorized to carry out the individual maintenance
jobs, maintenance personnel must have achieved a level of training and qualification appropriate to
the complexity of the task in hand. The various Qualification Levels QL1 to QL4 reflect the levels of
training offered in MTU courses and the contents of the tool kits required:
QL1: Operational monitoring and maintenance which can be carried out during a break
in operation without disassembling the engine.
QL3: Maintenance work which requires partial disassembly of the engine.
QL4: Maintenance work which requires complete disassembly of the engine.
The maintenance schedule matrix normally finishes with extended component maintenance. Following
this, maintenance work must then be continued at the specified intervals.
The "task numbers" stated in the list identify the respective maintenance items. They provide a reference to
the scope of parts required and appear on the labels of the appropriate replacement parts.
Preventive maintenance instructions
The specification of fluids and lubricants, guidelines for maintenance and change intervals as well as a list of
approved fluids and lubricants are provided in the MTU Fluids and Lubricants Specifications A001061 and the
component manufacturers’ fluids and lubricants specifications. They are therefore not listed in the maintenance
schedule (exception: deviations from the Fluids and Lubricants Specifications). Use only fluids and lubricants which
comply with the MTU Fluids and Lubricants Specification / are approved by the relevant component manufacturer.
Amongst other items, the operator/customer must carry out the following additional maintenance work:
• Protect rubber and synthetic parts from oil and fuel, never treat with organic detergents, only wipe with a dry cloth.
• Fuel prefilter:
The maintenance interval depends on how dirty the fuel is. The filter elements of the fuel prefilter
must be replaced every 2 years at the latest (Task 9998).
• Battery:
Battery maintenance depends on use and ambient conditions. The specifications of
the battery manufacturer must be obeyed.
Manufacturer’s specifications shall apply to the maintenance of all components not listed in this maintenance schedule.
Any maintenance items which are listed in this Maintenance Schedule but not included in the
equipment of the engine concerned can be disregarded.
Out-of-service periods
If the engine is to remain out of service for more than 1 month, carry out engine preservation in accordance
with the MTU Fluids and Lubricants Specifications, Publication No. A001061.
