Section 6 - Systems and Scheduled Maintenance
6.1. Operating Description
Information of special tools required and basic safety precautions.
Disassembly:
Use the correct tools and instruments. Serious injury or damage to the engine can
result from using the wrong tools and instruments.
Use an overhaul stand or work bench if necessary. Also, use assembly bins to keep
the engine parts in order of removal.
Lay down disassembled or cleaned parts in the order in which they were removed.
This will save you time at reassembly.
Pay attention to the marks on assemblies, components and parts for positions or
directions. Put on your own marks, if necessary, to aid reassembly.
Carefully check each part for faults during removal or cleaning. Signs of abnormal
wear will tell if parts or assemblies are functioning improperly.
When lifting or carrying heavy parts, get someone to help you if the part is too
awkward for one person to handle. Use jacks and chain blocks when necessary.
Reassembly:
Wash all engine parts, except oil seals, O-rings, rubber seals, etc. in cleaning solvent
and dry them.
Use only the correct tools and instruments.
Use only good quality lubricating oils and greases. Be sure to apply a coat of oil,
grease, or sealant to parts as specified.
Use a torque wrench to tighten parts when specified tightening torques is required.
Replace all gaskets and packing. Apply appropriate amount of adhesive or liquid
gasket when required.
Increase the frequency of maintenance in harsh duty conditions (frequent stops and
starts, dusty surrounding, prolonged winter season, no-load running).
Risk of burns during maintenance operations carried out when the engine is hot.
Wear suitable safety clothing.
It is strictly forbidden to clean the engine with compressed air.
It is strictly forbidden to perform maintenance/cleaning operations in the presence of
moving parts.
Use gloves, overalls, etc. to protect the body from burns.
6.2. Periodic Maintenance Schedule
The maintenance and fault diagnostic procedures involve risks that may cause severe
injury or even death. These procedures should therefore be carried out solely by qualified
electrical and mechanical specialists. Before any maintenance and cleaning work, make sure
that there are no moving parts, that the generator housing has cooled to ambient temperature,
that the electricity generating set cannot be accidentally started up and that all procedures are
strictly observed.
