5.8.1 Preparing the engine for storage
The following routine should be carried out when
it is known that the engine will not be required for
some months.
If the following procedure is not carried out the
engine should be run on full load for approximately
45 minutes once a month.
CAution
As a direct result of combustion the lubricating
oil may contain harmful acids and therefore
it should not be left in the sump if it is known
engine will not be used for extended periods.
a. Replace the fuel in the tank with a small supply
of suitable inhibition fluid.
b. Drain the lubricating oil from the sump and refill
with new oil.
c. Run the engine for a period to circulate the oil
through the system and to ensure the inhibition
fluid is passed through the fuel pumps and
injectors.
d. Stop the engine, drain the cooling system and
drain the lubricating oil from the sump.
The crankshaft should NOT be turned until the
engine is again required for service.
The inhibition fluid should be left in the fuel
system.
e. Seal all openings on the engine with tape.
f. Remove the batteries and store them fully charged
after coating the terminals with petroleum jelly.
g. Grease all external bright metal parts and the
speed control linkage.
h. Tie labels on the engine clearly stating what
steps have been taken to inhibit the engine
during storage.
5.8.2 returning the engine to service
Refer to the appropriate sections for the relevant
detailed instructions as necessary to complete this
work.
a. Remove the tie-on labels and all the protective
coverings from openings and apertures.
b. Check the drive belt for deterioration and correct
tension.
c. Check to ensure the drive belt pulley grooves
are corrosion free.
d. Fill the fuel tank.
e. Refill the cooling system, adding new coolant
concentrate to a 50% concentration.
f. Refill the lubricating oil sump with new oil of the
correct specification and viscosity.
g. Remove the batteries from store. If they are still
fully charged reconnect them to the engine.
Coat the terminals with petroleum jelly.
h. Start the engine and check for coolant, fuel and
oil leaks before applying load.
