SECTION - V
PERIODIC MAINTENANCE
Weichai engines are designed for high reliability and long life. The engines are built
to withstand marine operational environment. Preventive maintenance is the cost
effective and economical way to reduce the operational cost of a diesel engine. If
the preventive maintenance is carried out as per quality and schedule, downtime
and costly breakdowns can be eliminated.
The maintenance schedule is dened by the actual operating environment of the
engine. The maintenance schedule given in table 5.1 is for ideal operating condition.
In case of heavy dust or special situation, the frequency of the maintenance must
be increased.
5.1 Safety precautions
Before performing maintenance operations the engine operator must carefully read
and understand the instructions provided in this section. The operator must be
aware of and strictly follow the relevant operating instruction and safety precaution,
accident preventive measures, and obey generally recognized industrial safety
measures.
5.2 Importance of periodic maintenance
Life of the engine is mainly based on quality of fuel, lube oil and coolant, routine
inspection and maintenance and the hours of operation. Every routine inspection
and maintenance is designed to monitor the engine health and performance in a
desired interval and prevents unexpected breakdown. Proper maintenance reduces
the number of accidents due to poor machine performance and helps extend the
life of the engine. Refer table 5.1 for recommended maintenance interval.
5.3 Replacement of parts and components
As far as operation of parts and components is concerned, the customer must
follow relevant specications of the engine manufacturer and pay attention to
relevant terms and conditions. If any parts and components are to be replaced
during repair, then it is required to follow regulations concerning the replacement of
parts and components specied by manufacturer.
It is allowed to use only genuine spare parts on the engineprocured
from a reliable outlet of the engine manufacturer. If thecustomer
or
the service center has installed non-genuine spare parts and
sub-
assemblies, the supplier should take the responsibility and
bear all cost damage to engine which may subsequently occur
and damage and injury to persons and equipment within the legal
scope of product warranty.
