Filter Changes
Oil Filters:
If there is one thing you should remember it is this: Your oil is the lifeblood of your
engine. Cheap oil or old and dirty oil will lead to premature engine failure. Westerbeke
has made changing the oil very simple.
To change the oil start and run the engine for a few minutes to get it warm. This will
help the oil to flow better. Locate the oil drain hose attached to the front area of the
engine. Remove the cap from the end of the hose and place the hose in a container that
will hold a gallon of fluid. Once the oil has drained replace the cap on the hose and
reattach to the engine.
Installation Hints:
Use genuine parts. Aftermarket parts may fit, but we have had failures due to
incompatibility of parts. Especially oil filters. There is more to consider besides thread
and gasket surface matches
Use high-grade oil and advise your service tech to do the same. The few dollars saved on
low-grade oil will cost 100 times more in the long run.
When replacing the oil filter smear some oil on the o-ring seal and fill the filter half way
with new oil.
Change the oil at least once a season or every 100 hours. However it is best to change it
twice. One of these changes should be done at winter lay-up. Old oil has gathered
chemicals and combustion byproducts that can cause premature bearing and ring failure.
Refer to the manual for more detailed instructions.
Fuel Filters:
The Westerbeke engine uses either one or two fuel filters mounted to the engine. The
secondary, on engine filter is located in a cup mounted on the oil filter side of the engine.
Unscrewing the metal ring and gently pulling the cup down will give access to the filter.
The filter should stay on the filter body. Pull the filter off of
the body. There are two o-rings on this housing, one to seal the
inside of the filter to the housing, and the other to seal the cup
to the housing. There is an illustrated drawing on pages 39, 40,
and 41 of the Owner’s Manual, edition three. If so equipped
the other filter is located in the base of the fuel pump. The
pump will be round (not square). To remove the filter use a
17mm wrench on the base cap nut turning about 90°. The base
will come straight down and the filter is inside the pump.
There will be fuel spilled out when changing this type of filter.
New Westerbeke filters come with a complete set of both o-
rings and/or gaskets. If these parts are not in the new filter
packages, shop at some other store, you are not being sold
genuine parts.
Installation Hints:
When replacing fuel filters turn your battery switch to OFF.
Use a gentle touch. If you strong-arm small parts you will have
to replace more damaged pieces.
Westerbeke Engines are self-bleeding. After a fuel filter change hold your preheat button
in for a minute or so and the fuel system will fill itself. However when replacing your
large off engine mounted fuel filter/water separator it is always a good idea to fill this
with fuel.
After the old filters are removed, inspect the old filters for signs of problems.
