The engine troubleshooting

6.1 The alarm system fault

Item                      The reason of the malfunction                   Troubleshooting

4.The light of the air-in pressure and under voltage

1.The oil level is not enough
2.The oil filter is jam

1.The cooling water level of radiator is too low

2.The core of the radiator was too dirty.

4.Fan, water pump drive "V" belt loose.

5.The malfunction of cooling water pump.

1.The malfunction of battery

2.The malfunction of line
3.The malfunction of alternator

The element of air cleaner is so dirty

1. The alarm of lubricating oil

2. The light of cooling 
    water temperature

3.Charging light

Add oil
Change filter element

Add cooling water

Clean core of the radiator

Tighten or change

Service or change water pump

Check the electrolyte and charge
up anew or change battery
Check

service or change

Service or change generator

Blow clear or change the element by compress air

3.Cooling water leakage, Coo-
   ling water pipe is dirty.

Check the part of water leakage,

clear or change the cooling water pipe

6.2 Start failed

The reason of the malfunction                             Troubleshooting

A. Malfunction of the supply system

1. Fuel tank was empty 

2.Fuel system has air

3.The solenoid valve for oil off was not open

4.Fuel is incompetent

5.Air cleaner element is so dirty

6.The temperature of condition is too low 

7.The filter element of fuel is jam

8.Oil supply time is untrue

9.Injection head is jam

10. Inlet and exhaust port is untrue

11. The compression of air cylinder is not good 

a). Air valve is leakage

b).Air cylinder,piston,piston ring is heavy wear

12.The oil of injector pump is less

B. The malfunction of circuit

1.The battery power is not enough or tie-on loose

2.Starter engine is powerless, just idle running

3.Starter intermeshing is difficult

4.The rotation speed of starter is low 

Add fuel

Drain air

Change the right spec oil

Change the new filter element

Use the air heater

Change the diesel filter element 

Check or change oil nozzle parts

Check and adjust valve clearance

Service or lap the valve

Service by professional person

Put fuel injection pump on the experiment 

table to service and adjust

Check the wire tie-in or the battery of electr-

olyte level and weight then charge

Service or change starter engine

The voltage drop of battery is larger or the 

lead of battery is gracile in winter

Adjust the position between starter and flywheel gear 

Check air cylinder compression pressure and the sta-

ndard value is 3.1Mpa, lowest value is 2.2Mpa

Check and adjust advance angle of fuel supply

Check the action of solenoid valve, service or change
