威爾信帕金斯奧林匹亞發動機發電機預防性維護保養方法

Preventive maintenance

Preventive maintenance periods



These preventive maintenance periods apply to average conditions of operation. Chec k the periods given by

the manufacturer of the equipment in which the engine is installed. Use the periods which are shortest. When

the operation of the engine must conform to the local regulations these periods and procedures may need to

be adapted to ensure correct operation of the engine.

It is good preventive maintenance to check for leakage and loose fasteners at each service.

These maintenance periods apply only to engines that are operated with fuel and lubricating oil which conform

to the specifications given in this handbook.

How to check the amount of  the coolant

Check the coolant level when the engine is stopped and cool.

Warning! On a hot engine release the filler cap carefully as the system will be under pressure.

1  Remove the filler cap from the expansion tank slowly to relieve the pressure.

  Maintain the coolant level at the bottom of the filler pipe.



3  Clean the filler cap and check the condition of the filler cap gaskets. Renew the filler cap if the gaskets are

damaged. Fit the filler cap.

  Inspect the coolant system for leaks.

How to check the air cleaner service indicator

Caution: Do not operate the engine if there is a blockage in the air filter or the air duc ts. This can caus e

lubricating oil to enter the cylinders through the engine breather valve.

The air filter is fitted with a restriction indicator (A) which gives a visual warning when the filter needs a service.

When the red warning indicator is s een through the clear panel after the engine has stopped, the air filter

element must be renewed.

After a clean element has been fitted, press the reset button on the res triction indicator.

Environmental conditions have an important effect on the frequency at which the air filter needs to be serviced.

 

How to check the amount of lubricating oil


800 Series


Warning! Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to

contact the skin.

At the periods given in the service schedule use the dipstick to check the amount of lubricating oil in the sump.

1  Check the oil level with the engine stopped. The level must be maintained between the “L” mark and “H”

mark on the dipstick.

 If necessary, remove the oil filler cap and add more oil of the same grade and specification as that which is

already in the system. Do not overfill.

3  Clean and fit the oil filler cap.

How to drain the primary fuel filter

At the periods given in the service sc hedule, the bowl of the primary fuel filter must be checked and, if

necessary, drained.

1  Open the drain; the drain is self-ventilated. Use a suitable container to collect the water drained from the

filter housing. Dispose of the water safely.

  Close the drain. Tighten the drain valve securely to prevent air from entering the fuel system.


00 Series

Visual inspection

A visual inspection should take only a few minutes and can prevent costly repairs and acc idents.

For maximum engine life, ins pect the engine compartment before the engine is started. Look for items such

as oil or coolant leak s, loose fastenings, worn belts or loose connections. Repair as necessary.

The guards must be at the correc t positions. Repair damaged guards or renew missing guards.

Wipe all caps and plugs before the engine is serviced to reduce the chance of system contamination.

For any type of leak (coolant, lubricating oil or fuel), clean away the fluid. If a leak is observed, find the

source and correct the leak. If a leak is suspected, check the fluid levels frequently until the leak is found

and repaired.

Accumulated grease and/or oil on an engine is  a fire hazard. Remove it by steam cleaning or by the us e of

a high pressure water jet.

Ensure that the coolant pipes are fitted correctly and that they are secure. Check for leaks. Check the

condition of all pipes.

Inspect the coolant pump for leak s.


Note: The coolant pump seal is lubricated by the coolant in the coolant system. It is normal for a small amount

of leakage to occur as the engine cools and the parts contract.

l  Excessive coolant leakage may indicate the need to renew the coolant pump seal. For the removal of the

coolant pump and the installation of the coolant pump and/or coolant pump seals, refer to the Workshop

Manual.

l  Inspect the lubrication system for leaks at the front crankshaft seal, the rear crankshaft seal, the sump, the

oil filter and the roc ker cover. If many oil leaks are present, particularly on an old engine, there could be a

blockage of the engine breather.

l  Inspect the fuel system for leaks. Check for loose fuel line clamps or for loose ties on the fuel lines.

l  Inspect the ducts for the air inlet system and the elbows for cracks. Check also for loose clamps and check

the condition of mounting rubbers. Ensure that hoses and tubes are not in contact with other hoses, tubes,

wiring harnesses, etc.

l  Inspect the fan belts and the alternator belt for cracks, breaks or other damage. Where more than one belt

is used between two pulleys, all of the belts must be renewed together. Maximum belt life will only be

obtained if the belts are maintained at the correct tension.

l  Drain the water and sediment from fuel tanks on a daily basis to ensure that only clean fuel enters the fuel

system.

l  Inspect the wiring and the wiring harnesses for loose connections and for worn or frayed wires.

l  Inspect the earth s trap for a good connection and for good condition.

l  Inspect the ECM-to-cylinder head earth strap for a good connection and for good condition.

l  Disconnect any battery chargers which are not protected against the current drain of the s tarter motor.

Check the condition and the electrolyte level of the batteries, unless the engine is fitted with a maintenance

free battery.

l  Check the condition of the gauges. Renew any gauges that are cracked. Renew any gauge that cannot be

calibrated.

How to check the specific gravity of the coolant


800 Series


Warning! Do not remove the radiator cap while the engine is still hot and the system is under pressure

because dangerous hot coolant can be discharged.

Drain some c oolant from the coolant system after the engine has been stopped and before the formation of

sediment. Proceed as follows:

1  For mixtures which contain inhibited ethylene glycol:

l  Put a hydrometer, and a reliable thermometer, into the antifreeze mixture and chec k the readings on both

instruments.

l  Compare the readings obtained with the chart and adjust the strength of the mixture as necessary.

  For mixtures which contain inhibited propylene glycol:

l  Open the c over of the refractometer, check that the clear panel is clean and use a small s yringe to apply

three or four drops of the coolant mixture to the clear panel.

l  Spread the coolant over the full area of the clear panel and close the cover. Hold the refractometer

horizontally with the clear panel at the top and inspect the sample through the viewer.

l  Compare the reading with the c hart in the instructions; adjust the strength of the mixture as necessary.

Caution: The clear panel must be cleaned thoroughly before use. Some of the fluid which was tested earlier

can remain on the clear panel and this will affect the reading of the sample.
