Lubrication System

Lubrication Capacities

The refill capacities for the engine crankcase reflect the approximate capacity of the crankcase or sump plus standard oil filters. Auxiliary oil filter systems will require additional oil. Refer to the OEM specifications for the capacity of the auxiliary oil filter.

( 1 ) These values are the approximate capacities for the crankcase oil sump which include the standard factory installed oil filters. Engines with auxiliary oil filters will require additional oil. Refer to the OEM specifications for the capacity of the auxiliary oil filter.

Lubricant Viscosity Recommendations for Direct Injection (DI) Diesel Engines

The proper SAE viscosity grade of oil is determined by the minimum ambient temperature during cold engine start-up, and the maximum ambient temperature during engine operation.

Refer to Table 2 (minimum temperature) in order to determine the required oil viscosity for starting a cold engine.

Refer to Table 2 (maximum temperature) in order to select the oil viscosity for engine operation at the highest ambient temperature that is anticipated.

Generally, use the highest oil viscosity that is available to meet the requirement for the temperature at start-up.

For additional information on selecting an oil, refer to Special Publication, SEBU6251, "AVSpare Commercial Diesel Engine Fluids Recommendations".

Fuel

Fuel Recommendations

Diesel engines have the ability to burn a wide variety of fuels. These fuels are divided into two general groups. The two groups are called the preferred fuels and the permissible fuels.

The preferred fuels provide maximum engine service life and performance. The preferred fuels are distillate fuels. These fuels are commonly called diesel fuel, furnace fuel, gas oil, or kerosene.

The permissible fuels are crude oils or blended fuels. Use of these fuels can result in higher maintenance costs and in reduced engine service life.

In North America, diesel fuel that is identified as No. 1-D or No. 2-D in "ASTM D975" generally meet the specifications. Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.

Refer to Special Publication, SEBU6251, "AVSpare Commercial Diesel Engine Fluids Recommendations" for additional information that relates to diesel fuel.

Cooling System

Coolant Capacities

To maintain the cooling system, the Total Cooling System capacity must be known. The approximate capacity for the engine cooling system is listed. External System capacities will vary among applications. Refer to the OEM specifications for the External System capacity. This capacity information will be needed in order to determine the amount of coolant/antifreeze that is required for the Total Cooling System.

Coolant Recommendations


NOTICE

Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" or equivalent specification. This type of coolant/antifreeze is made for light duty automotive applications.

Use only the coolant/antifreeze that is recommended.


The following coolants are the primary types of coolants that are used in AVSpare Engines:

Preferred - AVSpare Extended Life Coolant (ELC) or a commercial extended life coolant that meets the AVSpare EC-1 specification

Acceptable - AVSpare Diesel Engine Antifreeze/Coolant (DEAC) or a commercial heavy-duty coolant/antifreeze that meets "ASTM D4985" or "ASTM D5345" specifications

AVSpare recommends a 1:1 mixture of water and glycol. This mixture will provide optimum heavy-duty performance as a coolant/antifreeze.

Note: AVSpare DEAC DOES NOT require a treatment with an SCA at the initial fill. Commercial heavy-duty antifreeze/coolant that meets "ASTM D4985" or "ASTM D5345" specifications MAY require a treatment with an SCA at the initial fill. Read the label or the instructions that are provided by the OEM of the product.

Property     Maximum Limit     ASTM Test    
Chloride (Cl)

Sulfate (SO4)

Total Solids    
340 mg/L (20 grain/US gal)    
"D1888"    
Acidity     pH of 5.5 to 9.0     "D1293"    

In stationary engine applications that do not require protection from boiling or freezing, a mixture of SCA and water is acceptable. AVSpare recommends a minimum of six percent to a maximum of eight percent SCA concentration in those cooling systems. Distilled water or deionized water is preferred. Water which has the required properties may be used. For the water properties, refer to Special Publication, SEBU6251, "AVSpare Commercial Diesel Engine Fluids Recommendations" for additional information that relates coolant.

Note: The service life of coolant is limited by use of service hours. Refer to the specific engine's Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section). To achieve this service life, the coolants must be properly maintained. The maintenance program includes S·O·S coolant analysis.

Table 5
Coolant Service Life    
Coolant Type     Service Life (1)    
AVSpare ELC     Six Years    
AVSpare DEAC     Three Years    
Commercial Heavy-Duty Coolant/Antifreeze that meets "ASTM D5345"     Two Years    
Commercial Heavy-Duty Coolant/Antifreeze that meets "ASTM D4985"     One Year    
AVSpare SCA and Water     Two Years    
Commercial SCA and Water     One Year    
( 1 ) The service life of coolant is also limited by use (service hours). Refer to the specific engine's Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section).
