Maintenance and servicing
Preface
Low operating and maintenance costs as well as operational reliability and availability depend on maintenance
and servicing being carried out in compliance with MTU’s specifications and instructions.
The overall system, of which the engine is an integral part, must be maintained in such a way as
to ensure trouble-free engine operation. For this purpose always:
• ensure that sufficient fuel of specified quality is available
• that the combustion air is dry and clean
Preventive maintenance instructions:
• Special care should be taken to keep the machinery plant in a clean and serviceable condition at all
times to facilitate detection of possible leaks and prevent subsequent damage.
• Protect rubber and synthetic parts from oil and fuel, never treat with organic detergents, only wipe with dry cloth.
• Always replace all seals and gaskets. Our Service partner will always be available should assistance be required.
MTU maintenance concept
The MTU maintenance concept is a preventive maintenance concept.
Preventive maintenance permits advance operational planning and increases availability. The maintenance
schedule refers to the specified load profile. The time intervals at which the maintenance work is to be carried
out, and the relevant checks and tasks involved, are average results based on operational experience and
therefore represent guidelines only. Specific operating conditions may require modifications to the Maintenance
Schedule. Exchange parts (reliabilt
®
) are available for components to be replaced.
Note
The maintenance task matrix covers all tasks up to a major overhaul. After a major overhaul, the maintenance
tasks must continue to be performed in accordance with the specified schedule.
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 Specification A001061. Use
only fluids and lubricants which comply with the MTU Fluids and Lubricants Specification.
The user/customer must perform the following additional maintenance tasks:
• Fuel prefilter:
Maintenance depends on fuel quality (purity). The filter elements of the fuel prefilter
must be replaced every 2 years at the latest.
• Battery:
Maintenance depends on load and ambient conditions of the batteries. The specifications
of the battery manufacturer are binding.
Out-of-service periods
If the engine is to remain out of service for more than 1 month, carry out engine preservation procedures
according to the Fluids and Lubricants Specification, MTU Publication No. A001061.
