Inhibiting
General
To prevent the engine and other equipment from being harmed during long (2 months or more) periods out of servi-
ce, it must be conserved. It is of utmost importance that the conservation is performed correctly. Therefore we
have compiled a checklist of the most important points. Before taking the engine out of service for long periods, it
should be checked by a Volvo Penta dealer for possible needed overhaul or repaire of the engine and other equip-
ment.
WARNING! Read the chapter “Maintenance” thoroughly before starting any maintenance work. It
contains directions for performing maintenance in a safe and correct manner. Certain preservatives are
flammable. Some are also dangerous to inhale. Provide good ventilation. Use a protective mask.
IMPORTANT! The following must be considered when cleaning with a high-pressure water jet: Never
point high-pressure water jets directly at seals, rubber hoses or electrical components. Never use the
high-pressure function when washing the engine.
Preparation
1. Drain the lubrication oil from the engine and fill it
with new lubrication oil or conserving oil.
IMPORTANT! Post a warning sign on the engine
that the conserving oil must be replaced with the
specified lubrication oil before starting the engine
again.
2. Run the engine on idling speed on a mixture of
70% fuel and 30% lubrication oil until the
complete fuel system is filled with the mixture,
then stop the engine (If possible, top up the fuel
tank to avoid condensation).
3. When the engine is coming to a stop but is still ro-
tating, spray volatile rust preservative in the air in-
take and exhaust system. This to prevent rust on
the intake system.
4. Apply a coat of rust preservative to the exposed,
machined surfaces of the engine.
5. Cover breather, air inlet and exhaust openings
with tape.
6. Loosen the alternator and water pump drive belts.
7. Tape the starter and alternator terminals and
cover the starter and alternator with a
polyethylene sheet. Put a desiccant inside the
covering.
IMPORTANT! Never use vinyl sheets for
covering. This can result in condensation and
harm the installation
8. Remove the batteries and charge them. Clean the
terminal posts and coat them with acid free
Vaseline. Keep the batteries in a dry, cool place.
9. Cover the engine for weather protection.
IMPORTANT! Store the engine in a well-
ventilated room.
IMPORTANT! It is not necessary to drain the
coolant because it contains coolant conditioner.
Care during Storage
Recharge the battery at least once a month.
IMPORTANT! During longer periods out of opera-
tion, the preparations must be repeated every 12
months.
Return the Engine to Service
1. Remove the covering from the engine.
2. Connect well-charged batteries to the engine.
3. Remove the covering from the starter and
alternator.
4. Adjust the alternator and water pump drive belts.
5. Remove all coverings and tapings.
6. Drain the rust preservative from the engine and fill
the engine with recommended engine oil.
7. Fill the fuel tank and prime the fuel system.
8. Check under and around the engine for such items
as loose or missing bolts, oil, fuel or coolant leaks
and repair if needed.
9. Remove the rocker covers and lubricate the valve
mechanism.
10. Crank the engine three times, 10 seconds each
time, at intervals of one minute, with the fuel
supply shut off, to make sure the oil pressure
rises properly.
12. Start the engine.
13. Allow the engine to warm up at low idle.
14. When the engine has run long enough to warm up
apply the load and bring it to operating speed.
