5 Maintenance
5.1 Preface
MTU maintenance concept
The following applies in the case of engines which are subject to emissions regulations:
Emissions regulations prohibit alteration, removal or addition of any mechanical or electronic component
or calibration that could affect the emissions characteristics of the engine. Maintenance, replacement, or
repair of emissions-relevant components, e.g. control devices, sensors, cylinder heads and exhaust
flaps, can only be performed using MTU approved components or equivalents.
Failure to adhere to the maintenance instructions could result in violation of legal requirements.
The MTU Maintenance Schedules ensure the reliability and performance of MTU engines and must be
complied with over the entire life cycle of the engine.the case of engines which are not subject to any
emissions regulations, the maintenance intervals cited are to be regarded as guideline values.
This maintenance schedule includes preventive and on-condition maintenance.
The maintenance schedule is based on the load profile / load factor specified below. Special operating
conditions and technical requirements may require additional maintenance work and/or modification of
the maintenance intervals. The intervals according to which the maintenance tasks have to be carried out
are specified as operating hours and time limits. The limit which occurs first is applicable.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 Qualifica‐
tion 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.
QL2: Component replacement (corrective only).
QL3: Maintenance work which requires partial disassembly of the engine.
QL4: Maintenance work which requires complete disassembly of the engine.
The maintenance schedule matrix finishes after 18 years at the latest. Following this, maintenance work
is to be continued at the intervals indicated.
The numbers specified in the measures list serve as reference to the required parts scope.
Notes on maintenance
Specifications for fluids and lubricants, guideline values for their maintenance and change intervals and
lists of recommended fluids and lubricants are contained in the MTU Fluids and Lubricants Specifications
A001063 and in the fluids and lubricants specifications produced by the component manufacturers. They
are therefore not included in the maintenance schedule (exception: deviations from the Fluids and Lubri‐
cants Specifications). All fluids and lubricants used must meet MTU specifications and be approved by
the relevant component manufacturer.
Amongst other items, the operator/customer must carry out the following additional maintenance work:
• Protect components made of rubber or synthetic material from oil. Never treat them with organic deter‐
gents. Wipe with a dry cloth only.
• Fuel prefilter:
The maintenance interval depends on how dirty the fuel is. The paper inserts in fuel prefilters must be
changed every two years at the latest (Task 9998).
• Battery:
Battery maintenance depends on the level of use and the ambient conditions. The specifications of the
battery manufacturer apply.
