• In the maintenance sheets the checks, maintenance, cleaning and repair works of the
maintenance sheets are briefly designated
• Under the designation "tools (W)" only special and additional tools are listed with the
MaK tool No. Not all of these tools are included in the normal scope of supply.
• Together with the engine type it will be indicated for what engine the job card is valid.
• The indicated personnel and time requirement does not define the working time of the
individual person.
• The indicated time is based on estimated mean values which may deviate according to
the equipment of the plant and its maintenance conditions. Wherever the required wor-
king time depends on the number of cylinders the indicated time of the maintenance
sheets refers to one cylinder unit only.
2.2.3 Maintenance schedule (Periodic maintenance work)
A large-scale plan showing all maintenance work up to the largest maintenance interval
clearly indicating all occurrences and the future work expenditure for the individual
components.
It would be useful to mount the plan on a wall; when this is not possible for space reasons,
it has to be folded and filed in the map “maintenance forms” *.
We cannot and will not give instructions for handling this plan but we will only give you
some guidelines how to use this plan as an aid for the maintenance system.
The work already carried out will be countersigned in fields intended for this purpose.
Different colours can be used to differentiate between the results, e.g.: green = no defects/
o.k.; yellow = readjustment/correction (e.g. clearances); red = damage/replacement of
parts.
Typical consumption parts which are replaced routinely or any time mounting is carried
out (O-ring seals, O-rings etc.) are not considered defective parts.
* The map will be handed over by the MaK service department for commissioning of the
engine
