Maintenance - Westerbeke 9.0 BCG Technical Manual

MAINTENANCE
Daily Checks (before initial daily start-up)
1. Check the level of lubrication oil in the engine's oil sump with the dipstick. Keep the oil level near the
upper mark of the dipstick.
2. Check the engine's fresh water coolant level in the plastic coolant recovery tank. (Maintain the coolant
level halfway between the ADD and MAX marks when cold.) Periodically check that the manifold is full
of coolant.
3. Periodically remove the generator's belt
guard and check the belt's tension. The
belt's tension should be between 3/8 to 1/2
inch deflection between the widest span of
the belt. Since belts stretch slightly, this
stretching will, to some degree, affect the
governor's action, the engine's ability to
cool, and with the 9.0 BTG, the alternator's
ability to charge.

4. Visually inspect the generator and engine; check for loose belts, chafed or broken wires, loose brack-
ets and fittings, damaged hoses, loose clamps, and any other eqUipment not properly secured.
5. Check the primary fuel filter/Water separator. Drain and service as required. (A primary fuel filter/water
separator is optional, but strongly recommended.)
Monthly
Check the condition of the zinc anode in the heat exchanger's
sea water circuit. Clean the anode, as required. Keep the area
inside the heat exchanger clean of zinc anode debris.
Fifty-Hour Service Check
1. Change the engine's lubrication oil and oil filter. Use a good
brand of oil with an SAE number suitable for your area's
temperature. The oil must have an API specification SC or
SO.
2. Retorque the cylinder head hold-down bolts (engine cold).
