Engine use and maintenance

Ø         Requires fuel, lubricating oil, coolant

Ø         Daily and weekly maintenance

Ø         Every 250h, 1500h, 4500h maintenance

Ø         Operational use

Engine fuel requirements

Ø         Fuel:

Using the number 0 or lower quality of light diesel oil

Using high temperature fuel filter plugging the power will decrease

Fuel use of higher temperatures, the engine start-up difficulties

After the shutdown of the fuel filter to put in hot water

Regular (250h) more filters

If the fuel used is dirty, clogged filter will advance

Engine power will decrease after the filter clogging

Engine oil requirements (1)

Ø      Lubricants:

Compliance with SAE 15W40 viscosity

Quality meets API CF or higher grade

Regular (250h) to replace the oil and filter

You must use CF4 or above the level of oil in the highlands

Deterioration in the highlands engine combustion, oil pollution quickly, CF4 below the level of the oil life of less than 250h

Change over the life of the engine will not be normal oil lubrication, wear and tear, appear early failures

Engine oil requirements (2)

Ø         Plateau used lubricants:

Quality meets API CF4 or higher level

If you use a CD of low grade oil drain intervals should be shortened by half

Engine coolant requirements (1)

Ø        Coolant:

Required to use water filters or add DCA dry to prevent cooling system corrosion, cavitation and scaling.

Check the radiator and the cooling system pressure cap sealing leaks, the boiling point of the coolant to ensure not reduced, the cooling system is normal.

Engine coolant requirements (2)

In cold areas should use glycol + under running water coolant or manufacturer-approved antifreeze used to meet the environmental conditions. 
DCA regularly check the coolant concentration and freezing.

Engine operation using

Ø         In some sections running, the altitude exceeds the design value, the load should be reduced to improve the black smoke, reduce exhaust temperature to ensure reliability.

Ø        In the cold season when the engine is started, consecutive start time not too long (up to 30s), so as to avoid damage to the battery and the starter. In the cold season warming the battery (up to 58 ℃), enabling the charging and discharging normally.

Ø         In order to increase the heavy load do not immediately run after the engine is started cold season, so as not to damage the engine, pay attention to oil pressure, water temperature to normal load operation。

Ø         Heavy shutdown conditions should be empty load or idle running 2-3 minutes after shutdown, otherwise easily damage the turbocharger and make living in Sierra cylinder.

 

Daily inspection and maintenance engine

Ø        Lubricants and cooling liquid surface

Ø         Fuel, oil, coolant leak

Ø         And wear a belt slack

Ø         Fan for damage

Ø         Sound any abnormal sound

Ø         Smoked without exception

Ø         Whether the change in dynamics

Ø         Oil pressure and coolant temperature

 

Weekly engine inspection and maintenance

Ø         Check the intake resistance indicator, or replace the air filter

Ø         Let go of the fuel tank in the water and sediment

Ø         Release the fuel filter water and sediment

Ø         If the fuel used in dirty or low ambient temperatures

Ø         Tank and filter will produce more condensate

Ø         Should be deposited daily water discharge

 

Each 250h engine inspection and maintenance

Ø         Replace the engine oil

Ø         Replace the oil filter

Ø         Replace the fuel filter

Ø        Replace the water filter

Ø         Check the coolant concentration DCA

Ø         Check coolant freezing (cold season)

Ø         Check or clean the dust tank clogged heatsink

 

 

Each 1500h engine inspection and maintenance

Ø        Check and adjust valve clearance

Ø         Check and adjust the injector lift

 

 

 

 

Each 4500h engine inspection and maintenance

Ø         adjust injectors and fuel pump calibration

Ø         Check or replace the following parts:

–         Turbocharger

–         Pump

–         Tensioner

–         Fan Hub

–         Compressor

–         Charger

–         Cold start auxiliary heater
