LAY-UP AND RECOMMISSIONING
STARTER MOTOR
Lubrication and cleaning of the starter drive pinion is advis-
able, if access to the starter permits its removal. Make
slIre
the battery connections arc shut off before attempting to
remove the starter. Take care in properly replacing any elec-
trical connections removed from the starter.
CYLINDER LUBRICATION
It is not necessary to remove the glow plugs from the cylin-
der head to squirt light engine oil into the cylinders for the
few months of normal lay-up. However, if you anticipate a
longer lay-up period (12 months or more), we recommend
that this procedure be performed. The light oil in the cylin-
ders will prevent the pistons' rings from sticking to the cylin-
der walls. With oil in the cylinders, turn the engine over by
hand two revolutions.
TRANSMISSION
Check or change fluid in the transmission as required. Keep

prevent corrosion. Wipe off grime and grease and
touch up unpainted areas. Protect coupling and output flange
with anticorrosion coating.
SPARES
Lay-up time provides a good opportunity to inspect your
UNIVERSAL engine to see if external items such as drive
belts or coolant hoses need replacement. Check your basic
spares kit and order items not on hand, or replace those items
used during the lay-up, such as filters and zinc anodes.
BATTERIES
If batteries are to be left on board during the lay-up period,
make sure they are fully charged and will remain that way, to
prevent them from freezing. If you have any doubt that the
batteries will not remain fully charged, or that they will be
subjected to severe environmental conditions, remove the
batteries and store them in a warmer, more compatible envi-
ronment.
A
WARNING:
Lead acid batteries emit hydrogen,
a
highly explosive gas, which can be ignited by electrical
arcing or lighted tobacco products. Do not smoke or
allow an open flame near the battery being serviced.
Shut off all electrical equipment in the vicinity to pre-
vent electrical arcing during servicing. Wear rubber
gloves,
a
rubber apron and eye protection when servic-
ing batteries.

RECOMMISSIONING
The recommissioning of your UNIVERSAL engine after a
seasonal lay-up generally foHows the same procedures as
those presented in the PREPARATIONS FOR STARTING
section regarding preparation for starting and normal starts.
However, some of the lay-up procedures will need to be
counteracted before starting the engine.
1. Remove the oil-soaked cloths from the intake manifold.
2. Remove the raw water pump cover and gasket. Discard
the gao;;ket. Install the raw water pump impeller removed
during Jay-up (or a replacement, if required). Install the
raw water pump cover with a new cover gasket.
3.
Reconnect the shaft coupling and check
for
proper align-
ment.
4. Reinstall the batteries that were removed during the lay~
up, and reconnect the battery cables, making sure the ter-
minals are clean and that the connections are tight. Check
to make sure the batteries are fully charged.
5. Check the condition of the zinc anode in the raw water
circuit and clean or replace the anode ao;; net!ded. Note that
it is not necessary to flush the antifreeze/freshwater solu-
tion from the raw water coolant system. When the engine
is put into operation, the system will self-flush in a short
period of time with no adverse affects.
6. Start the engine in accordance with procedures in the
PREPARATIONS FOR INITIAL START-UP section of
this manual.
