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 level 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. Special operating conditions
and technical requirements may require additional maintenance work and/or modifications of the maintenance
intervals. Maintenance personnel charged with carrying out maintenance work must be appropriately qualified
depending on the complexity of the task concerned. 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.
QL2: Exchange of components (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 normally finishes with extended component maintenance. Following
this, maintenance work is to be continued at the intervals indicated.
The "Task" numbers stated in the list of jobs to be done/action to be taken indicate the relevant maintenance item. They
serve as a reference for the scope of parts needed and also appear on the labels of the corresponding spare parts.
Preventive maintenance instructions
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 A001061 and in
the fluids and lubricants specifications produced by the component manufacturers. They are therefore not listed in
the maintenance schedule (exception: deviations from the Fluids and Lubricants Specifications). Only use fluids
and lubricants which meet MTU specifications or are approved by the component manufacturer concerned.
Amongst other items, the operator/customer must perform the following additional maintenance work:
• Protect components made of rubber or synthetic material from oil. Never treat them
with organic detergents. 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 replaced every 2 years at the latest (Task 9998).
• Battery:
Battery maintenance depends on use and ambient conditions. The battery
manufacturer's instructions must be obeyed.
The relevant manufacturer's instructions apply with respect to the maintenance of any components
which do not appear in this maintenance schedule.
Items that are listed in this maintenance schedule but that do not refer to the respective engine model, can be ignored.
Out-of-service periods
If the engine is to remain out of service for more than 1 month, carry out engine preservation procedures in
accordance with the MTU Fluids and Lubricants Specifications, Publication No. A001061/.
