Maintenance And Adjustments - Westerbeke 12C-TWO Operators Manual And Installation Manual

MAINTENANCE AND ADJUSTMENTS
Introduction
This section contains a scheduled preventive maintenance program and several adjustment procedures the
owner/operator can perform without the benefit of sophisticated and expensive tools and instruments.
Preventive Maintenance
Perform the preventive maintenance in accordance with the schedules listed in the following paragraphs.
Adherence to these schedules will ensure the equipment is maintained in the best possible condition and
that it will perform to expectations. Those items marked by an asterisk (*) are recommended to be
performed by an authorized dealer or distributor.
Daily (before each use)
I. Check the oil sump level. Maintain the oil level at or near upper level mark on dipstick.
2.
Check the coolant level in the plastic recovery tank. Maintain this level at or above the level marked
ADD.
3. Check the transmission's lubricant level, and add additional lubricant as needed.
4. Visually inspect the unit; check for loose belts, chafed or broken wires, loose brackets and fittings,
damaged hoses, loose clamps, and other equipment not properly secured.
5. Check the fuel supply. Fill tank(s) with a good grade of No. 2 diesel fuel, if required.
6. Check the primary filter/water separator. Drain and service as required.
(A primary filter/water
separator is optional, but strongly recommended.)
7. Check the engine's gauges or lights for proper oil pressure, operating temperature, and starting battery
charging voltage once the engine is operating.
8. Check the alternator's output gauge (ifinstalled) for proper DC voltage.
Monthly
Check the condition of the zinc anode in the heat exchanger's sea water circuit. Clean or replace the
anode as required. Keep the area inside the heat exchanger clean of zinc anode debris.
Servicing After Initial 50 Hours of Operation
1. Change the engine's lubrication oil and oil filter.
2. Replace the fuel filter element in the on-engine filter and in the optional water/sediment separator, if a
separator has been installed.
*3. Torque the cylinder head hold-down bolts.
