MAINTENANCE
7/73 - 10/53
Remove the Engine from Long Term Storage
To remove the engine from long term storage, follow the following
steps:
•
Flush the engine preservative oil out of the engine by removing the
plug from the main engine oil rifle and pumping a hot, lightweight
mineral oil through it. Make sure that the engine crankshaft is barred
at least three to four revolutions during this flushing procedure.
•
Drain all the mineral oil that was used to flush the engine clean of
the engine preservative oil.
•
Install the drain plugs.
•
Install new oil, fuel and coolant filters.
•
Fill the engine to the high mark with engine oil.
•
If the engine has been in storage for less than 24 months and if the
cooling system was drained, fill the cooling system with coolant.
See the Coolant Recommendations and Specifications procedure
in Section V of the corresponding owners and/or operation and
maintenance manual for antifreeze, water, and SCA specifications.
•
If the engine has been in storage for 24 months, every 24 months
the engine cooling system
must
be drained and flushed with a
suitable solvent or a hot, lightweight mineral oil. Fill the cooling
system with coolant. See the Coolant Recommendations and
Specifications procedure in Section V of the corresponding owners
and/or operation and maintenance manual for antifreeze, water,
and SCA specifications.
•
If the engine has been in storage for less than 24 months and the
engine has an extended life coolant with a rust inhibitor, drain the
cooling system. Fill the cooling system with coolant. See the
Coolant Recommendations and Specifications procedure in
Section V of the corresponding owners and/or operation and
maintenance manual for antifreeze, water, and SCA specifications.
•
Adjust the engine brake (if applicable) and valve clearances.
Reference the Overhead Set procedure in the corresponding base
Troubleshooting and Repair Manual or Service Manual for the
engine being serviced.
•
Tighten the intake and exhaust manifold mounting capscrews.
•
Prime the lubricating system.
•
Reinstall any external drive belts that were removed.
•
Replace all spark plugs. Reference the Spark Plugs procedure in
the corresponding base Troubleshooting and Repair Manual or
Service Manual for engine being serviced (if applicable).
•
Make sure all fuel lines are securely tightened and all fuel shutoff
valves are open prior to attempting to start the engine.
•
Start the engine.
•
Install the exhaust aftertreatment components (if applicable).
•
Force an active regeneration (if applicable).
DECOMMISSIONING
When the machine is to be permanently decommissioned or
dismantled, it is important to ensure that all hazard risks are either
eliminated or notified to the recipient of the machine. In particular:-
•
Do not destroy batteries or components containing asbestos
without containing the materials safely.
•
Do not dispose of any pressure vessel that is not clearly marked
with its relevant data plate information or rendered unusable by
drilling, cutting etc.
•
Do not allow lubricants or coolants to be released into land surfaces
or drains.
•
Do not dispose of a complete machine without documentation
relating to instructions for its use.
LONG TERM STORAGE RECOMMENDATIONS
(6 months or more)
Spare Airends
•
Long-term storage of airends should include filling the airend with
the standard compressor fluid, PRO-TEC, XHP605 or XHP405.
Upon installation of the airend, drain the storage oil from the airend
and proceed with the installation, assuring fresh oil is poured into
the intake prior to start up.
Portable Compressors
•
Airend – Remove the intake connection and pour the airend intake
full with Doosan compressor fluid PRO-TEC, XHP605 or XHP405.
Reconnect the intake connection.
•
Engine cooling system – Treat with rust inhibitor and drain.
Checkwith engine dealer for further recommendations.
•
Compressor Oil Filter/s- fill with Doosan compressor fluid PROTEC,
XHP605 or XHP405.
•
Seal all opening with waterproof tape.
•
Place a desiccant in the exhaust pipes, engine and compressor air
intake pipes.
•
Loosen tension on belts, fan, airend, etc.
•
Block axles so tyres are off ground and do not support any weight.
•
Disconnect battery cables.
•
Drain fuel system.
SHORT TERM STORAGE
Machines that stand idle for extended periods of time greater than
30 days:
•
Start and operate the machine every 30 days. Operate long enough
to allow the engine and compressor to reach operating
temperature.
•
Open and close the service valve to exercise machine from full load
to idle RPM.
•
Drain fuel tank to remove any water.
•
Drain water from fuel water separator.
COMPRESSOR MOUNTING
Portable compressors, which are modified to remove the running gear
and mount the compressor directly to trailers, truck beds or frames, etc.
may experience failure of the enclosure, frame, and/or other
components.
CAUTION:
To reduce the possibility of personal injury, avoid direct
contact of hot oil with your skin.
Note that it might take multiple cranking attempts to start the engine.
Do
not
crank the engine more than 30 seconds at a time as this
might cause the starter to overheat and fail.
Note that the engine might run rough until the fuel system is
completely primed or until all residual fuel system preservative oil is
completely flushed out of the fuel system (if the fuel has been
treated with fuel system preservative oil).
