CG958G Wheel Loader. Manual - part 30

- 124 - 

As the coolant additive is used, the concentration in the cooling system may 

increase by 3%~6% to prevent corrosion. 

In order to excessive antirust in the cooling system of the engine, the 

concentration of the coolant additive shall not exceed the maximum 6% we 

recommend. 

For a higher concentration of the additive, precipitation may be formed possibly 

at the high-temperature surface of the cooling system, and an adiabatic layer may be 

formed to weaken the heat exchange performance of the engine. The decrease of the 

heat exchange rate will possibly cause the crack of the cylinder end and other 

high-temperature parts. The higher concentration of the additive will also increase 

wear of the water pump’s seal.   

As the premixed coolant of the anti-icing liquid is not used, the coolant additive 

shall be added.   

As the coolant is added into the new or reworked engine for the first time, if the 

antifreezing agent above is not used, 1L ancillary coolant additive or corresponding 

matter shall be added in each 30L coolant, so the concentration of the ancillary 

additive in the cooling system occupies up 3%~6%. 

In order to maintain the concentration of 3%~6%, every 250 hours or in oil 

replacement (later or first), the ancillary additive shall be added.

V    Use Rule of Fuel

 

5.1 Precautions on Use of Fuel 

 Upon completion of work every day, as the fuel is added, the wet air shall be 

discharged so as to avoid condensation. 

 Do not top off the fuel tank because the fuel possibly expands and overflows as 

the temperature increases. 

 Prior to installing the fuel filter, the fuel shall not be added into the fuel box. The 

fuel with foreign substances will accelerate the wear of the fuel system’s parts.   

 The fuel to be added shall be settled for 72 hours to ensure its cleanness. 

 After beginning to add or filling the fuel into the fuel box, retention time of 5-10 

minutes is allowed to discharge the water and precipitate from the fuel box. 

Upon the replacement of the fuel filter, the air shall be discharged from the 

system. 

 Prior to filling up the fuel box, the water and precipitate in the fuel box shall be 

discharged weekly to prevent that the water and precipitate access into the fuel 

system. 

 Only the fuel recommended in this section can be used. 

5.2 Category of Fuel   

In order to offer optimal performance and service life of the engine, the fuel 

engine for the CCG958G loader allows the use of distilled fuel, i.e. diesel fuel, fuel 

oil and gas oil.

VI Use Rule of Operation Oil 

Materials on Operation Oil 

Some abbreviations shall be subject to the terms of SAE J754, and others shall 

be subject to the ones of SAE J183 by levels. In the table of “Density of Operation 

Oil”, the recommended working density is available. 

6.1 Diesel Engine Oil 

Please use the following recommended diesel engine oil: API CD/SD, CD/SE, 

CD/SF, CD/SG or CD. 

 The percentage of sulfur in fuel will affect the use of the diesel. For the effect of 

the sulfur content in fuel, the remaining and ingredients of the engine oil may be 

evaluated with infrared analysis method and ASTM D2896 procedures. The 

production of sulfide depends on the sulfur content in fuel, recipe of lubricant, 

working conditions of engine and ambient temperature etc. 

 It is a common rule that the TBN of the diesel oil is 20 times of sulfur content in 

fuel. It may be modified by analyzing the oil employed. The effect of recipe of the 

lubricant depends on the ingredient of the additive. The balanced additive mixture 

of low TBN has the effects same as the additive mixture of high TBN. Based on 

the analysis on the oil employed, these results may be attained. 

Going against the suggestions above may shorten the service life of engine 

due to carbon precipitate or excessive wear. 

Selection of engine oil: The engine oil CF above shall be adopted.

6.2 Hydraulic System Oil 

 

 The hydraulic oil employed may enable the components and hydraulic 

transmission parts of the hydraulic system to attain a longer service life and 

optimal working performance. In most hydraulic systems, the following 

recommended hydraulic oil shall be used: API CC, CC/SF, CD/SF, CD/SG, CD, 

CE/SF, CE/SG or CE. 

 In case the oil of different viscosity is required due to extremely bad ambient 

temperature, the engine oil recommended by the SICHUAN CHENGDU 

CHENGGONG CONSTRUCTION MACHINERY CO., LTD. may be used. 

 The industrial hydraulic oil that is applied to large load and has anticorrosion, 

anti-bubble, antirust and anti-oxidation additives may be used. 

 This machine adopts Mobil DTE25-antiwear hydraulic oil. 

6.3 Transmission Fluid 

 Using the oil recommended by the SICHUAN CHENGDU CHENGGONG 

CONSTRUCTION MACHINERY CO., LTD. may enable the transmission box to 

attain a longer service life and optimal performance. The oil for transmission 

box/transmission system oil recommended by the SICHUAN CHENGDU 

CHENGGONG CONSTRUCTION MACHINERY CO., LTD. is the one in 

conformity with the API CD/TO-2 code. 

 Going against the suggestions above will possibly shorten the service life of the
