04. Maintenance Schedule
04.1 General
The actual operating conditions, and above all the quality of the
fuel used, will largely determine the maintenance necessary for
the engine. Because of the difficulty in anticipating the various
operating conditions that may be encountered in the field, the
periods stated in the schedule should be used for guidance pur-
poses only, but must not be exceeded during the warranty period.
Where any indications are encountered that the performance of
a maintenance procedure is required in advance of the recom-
mended time period, prudent industry practice dictates that the
suggested maintenance procedure be performed. Additionally,
where inspection or observation reveals that a part shows wear
or use beyond the prescribed tolerances, that part should be
renewed immediately.
See also the instruction books of the turbocharger separate in-
structions for additional equipment and chapter 03.
1 Before any steps are taken,
carefully read the corre-
sponding item in this Manual.
2 Note the Risk Reduction
in chapter 00A.
3 Note the Environmental Hazards
in chapter 02A.
4 At all maintenance work,
observe the utmost cleanli-
ness and order.
5 Before dismantling,
check that all systems concerned are
drained or the pressure released . After dismantling, im-
mediately cover holes for lubricating oil, fuel oil and air with
tape, plugs, clean cloth or the like.
6 When exchanging a worn-out or damaged part
pro-
vided with an identification mark stating cylinder or bearing
number, mark the new part with the same number on the same
spot. Every exchange should be entered in the engine log and
the reason should be clearly stated.
7 Always renew all gaskets, sealing rings and O-rings
at
maintenance work. Note! The O-rings in the cooling water
system must not be lubricated with oil based lubricants, use
soap or similar.
8 After reassembling,
check that all screws and nuts are
tightened and locked, if necessary.
