Basic requirements for maintenance and service work
Customers performing their own maintenance must ensure that the following conditions and basic requirements are
satisfied:
− Observation of all safety regulations
− Provision a of comprehensive assortment of general-purpose tools
− Provision of cleaning and testing equipment
− Performance of work by trained personnel
− Provision of special tools
− Adequate equipping of service area
− Use of genuine MTU spare parts
General assembly instructions
• Component cleanness:
Clean the removed parts with cold cleaner or a similar substance and immerse in engine oil SAE 30 to protect
against corrosion.
To clean components with combustion residues, immerse in decarboniser.
Areas of all components that come into contact with oil, fuel, coolant, water and combustion air must be clean.
• Components requiring "special cleanness" (e.g. oil and fuel-carrying components) must be cleaned with suitable
cleaning procedures before assembly, checked for particular cleanness and treated accordingly.
• Elastomer components (e.g. rubber and similar) must not be washed with diesel fuel, solvent or cold cleaners.
Parts dirtied with oil and fuel must be cleaned immediately.
The parts should be wiped with a dry cloth.
Elastomer parts, e.g. engine mounts, damping elements, couplings and V-belts, are not to be painted and must
be covered over before all painting work.
Note: Component packaging must only be removed immediately before installation.
• Radial-lip shaft seals treated by the manufacturer with oil show as a result definite signs of swelling when
delivered. They must therefore be cleaned (not washed) only with an abrasion-proof paper cloth before
installation.
• The surfaces of parts that slide against each other must be lubricated with SAE30 engine oil when installed,
unless otherwise specified.
• Before installing shaft seals:
On the shaft, the sealing lip of the shaft seal must be coated with petroleum jelly and the shaft running surface
with thin-film lubricant or SAE30 engine oil.
In the support bore, the outer surface of metal outer jackets - unless otherwise specified in the drawing - must be
coated with surface sealant. For elastomer outer jackets or combined metal/elastomer outer jackets, the outer
surface must be coated with denaturated ethanol.
This symbol applies to radial-lip shaft seals and its significance depends on its position.
The arrow indicates the position of the sealing lip.
• O-rings and surfaces (bores and shafts) moving against them during installation must be coated with petroleum
jelly, unless otherwise specified.
When installing O-rings with counter-rings in coolant pumps, always follow the installation instructions.
