LAY-UP & RECOMMISSIONING
Starter Motor
-,
Lubrication and cleaaing 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 aay electrical
connections removed from the starter.
Cylinder Lubrication [Diesel]
If you anticipate a long lay-up period (12 months or more)
WESTERBEKE recommends you coat the engine cylinders
with SAE #40 oil. To do this, either remove the glow plug for
each cylinder or the fuel injector, which ever is easiest. Squirt a
good quantity of oil into each cylinder. Then rotate the engine
crankshaft by hand slowly two revolutions. Re-install the glow
plugs or injectors. Make sure you have available aay sealing
washers that may be needed for the injectors return line ..
Intake Manifold [Gasoline]
Clean the filter screen in the flame arrester, aad place a clean
cloth lightly soaked in lube oil around the flame arrester to
block any opening. Also place aa oil-soaked cloth in the
through-hull exhaust
port, Make a note to remove cloths prior
to start-up!
Cylinder Lubrication [Gasoline]
With the engine running, spray the fogging oil into the open
intake, stalling the engine. This will lubricate, the valves aad
cylinders ..
NDTE: At spring commissioning, remove and clean the spark
plugs and rotate the engine by hand two complete revolutions.
Re-install the spar.k plugs, tighten properly and reconnect 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, aad 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 flame near the battery being
serviced. Shut off 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 aad grease aad 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
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 aad 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, or pipe. Do not smoke or allow an open
flame near the battery being serviced. Shut off all
electrical equipment in the vicinity to prevllnt eillctrical
arcing during servicing.
4. Remove the spark plugs, wipe cleaa, re-gap, and install to
proper tightness [gasoline J.
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 accordaace with procedures described
in
the PREPARATIONS FOR STARTING section of this
maaual.
