LAY-UP
&
RECOMMISSIONING
Starter Motor
Lubrication and cleaning
of
the starter drive pinion is advisable,
if access to the starter permits its easy removal. Make sure the
battery connections are shut off before attempting to remove
the starter. Take care in properly replacing any electrical
connections removed from the starter.
Cylinder Lubrication [Diesel]
If you anticipate a long lay-up period
(12
months or more)
WESTERBEKE recommends removing the fuel injectors for
access to the cylinders. Squirt light lubricating oil into the
cylinders to prevent the piston rings from sticking to the
cylinder walls.
Make sure you have a replacements for the injector and return
line sealing washers.
Intake Manifold [Gasoline]
Clean the filter screen in the flame arrester, and place a clean
cloth lightly soaked in lube oil around the flame arrester to
block any opening. Also place an oil-soaked cloth in the
through-hull exhaust port, Make a note to remove cloths prior
to start-up!
Cylinder Lubrication [Gasoline]
After engine shutdown, remove the spark plugs and spray a
small amount of fogging oil into each cylinder. Rotate the
crankshaft manually two complete revolutions. Re-install the
spark plugs loosely for winter lay-up.
NOTE: At spring commissioning, remove the plugs
and
rotate
the
crankshaft two full revolutions. Re-install the spark plugs,
tightening properly and connecting the high tension leads fully
onto each spark plug.
Batteries
If batteries
are
to be left on board during the lay-up period,
make sure that they are fully charged, and will remain that way,
to prevent them from freezing. If there is 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
environment
A
WARNING:
Lead acid batteries emit hydrogen. a
highly-explosive gas. which can be ignited by electrical
arcing or a lighted cigarette. cigar, or pipe. Do not
smoke or allow an open game near the battery being
serviced. Shut
0"
all electrical equipment in the vicinity
to prevent electrical arcing during servicing.
Transmission [Propulsion Engine]
Check or change the fluid in the transmission as required Wipe
off grime and grease and touch up any unpainted areas. Protect
the coupling and the output flange with an anti-corrosion
coating. Check that the transmission vent is open. For
additional information, refer to the TRANSMISSION SECTION.
Spare Parts
Lay-up time provides a good opportunity to inspect your
Westerbeke 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. Refer to the
SPARE PARTS section of this manual.
Recommissioning
The recommissioning of your Westerbeke engine after a
seasonal lay-up generally follows the same procedures as
those described in the PREPARATIONS FOR STARTING sec-
tion 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 and
discard the old gasket. Install the raw water pump impeller
removed during lay-up (or a replacement, if required).
Install the raw water pump cover with a new cover gasket.
3. Reinstall the batteries that were removed during the
lay-up, and reconnect the battery cables, making sure the
terminals are clean and that the connections are tight.
Check to make sure that the batteries
are
fully charged.
A
CAUTION:
Wear rubber gloves, a rubber apron.
and eye protection when servicing batteries. Lead acid
batteries emit hydrogen,
a
highly explosive gas. which
can be ignited by electrical arcing
or a
lighted
Cigarette, cigar,
Dr
pipe. Do not smoke
Dr
allow an
open
game near the battery being serviced. Shut off all
electrical equipment in the vicinity to prellent electrical
arcing during serviCing.
4. Remove the spark plugs, wipe
clean,
re-gap, and install
to
proper tightness [gasoline].
5. Check the condition of the zinc anode in the raw water
circuit and clean or replace the anode as needed. Note
that it is not necessary to flush the antifreeze/fresh water
solution 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.
It
is
advisable, as either an end of season or recommissioning
service, to inspect the area where the zinc is located in the
heat exchanger and
clear
any and all zinc debris from that
area.
6. Start the engine in accordance with procedures described
in the PREPARATIONS FOR STARTING section of this
manual.
