Lubrication System

Note: Instructions for the installation of the filter are printed on the side of each AVSpare spin-on filter. For non-AVSpare filters, refer to the installation instructions that are provided by the supplier of the filter.

Lubricant Recommendations

Due to significant variations in the quality and in the performance of commercially available oils, AVSpare recommends the following oils:

  • Cat DEO (Diesel Engine Oil) (10W-30)

  • Cat DEO (Diesel Engine Oil) (15W-40)

  • Cat DEO-ULS (Diesel Engine Oil - Ultra Low Sulfur) (15W-40)

Note: Cat DEO-ULS multigrade is the preferred oil for use in all Cat diesel engines where SAE 15W-40 is the preferred viscosity grade.

Commercial Oils

Note: Non-AVSpare commercial oils are as a group second choice oils. This group of second choice oils are rated by performance.


NOTICE

AVSpare does not warrant the quality or performance of non-AVSpare fluids.


AVSpare developed the Engine Crankcase Fluid (ECF) specifications in order to ensure the availability of high performance commercial diesel engine oils. When the high performance commercial diesel engine oils are used properly, the availability of the high performance commercial diesel engine oils provides satisfactory life in the Cat Diesel Engines.

Note: If Cat DEO multigrade or DEO-ULS multigrade oils are not used, use only commercial oils that meet the following categories/specifications:

  • Commercial oils that meet the requirements of the Cat ECF-1-a, Cat ECF-2, and/or the Cat ECF-3 specification are acceptable for use in Cat diesel engines that are covered by this Operation and Maintenance Manual. API category oils that have not met the requirements of at least one Cat ECF specification may cause reduced engine life.

  • Commercial oils that meet the requirements of the Cat ECF-3 specification or meet the requirements of the API CJ-4 oil category are the preferred commercial alternative oils.

Oils that meet the requirements of the API CJ-4 oil category are compliant with the Cat ECF-3 specification.

The following catagories of oils are not approved for use in your AVSpare Engine:API CF, API CF-4 and API CG-4.


NOTICE

Do not use single grade API CF oils or multigrade API CF oil.


Engine Oil Viscosities


NOTICE

In selecting oil for any engine application, both the oil viscosity and oil performance category/specification as specified by the engine manufacturer must be defined and satisfied. Using only one of these parameters will not sufficiently define oil for an engine application.


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. To determine the oil viscosity that is required for starting a cold soaked engine, refer to the minimum temperature in Table 1. To select the oil viscosity for operation at the highest anticipated ambient temperature, refer to the maximum temperature in the Table. Use the highest oil viscosity that is available in order to meet the required temperature during start-up.

Table 1
Engine Oil Viscosities for Ambient Temperatures 
  Ambient Temperature 
Viscosity Grade  Minimum  Maximum 
SAE 0W-20  −40 °C (−40 °F)  10 °C (50 °F) 
SAE 0W-30  −40 °C (−40 °F)  30 °C (86 °F) 
SAE 0W-40  −40 °C (−40 °F)  40 °C (104 °F) 
SAE 5W-30  −30 °C (−22 °F)  30 °C (86 °F) 
SAE 5W-40  −30 °C (−22 °F)  50 °C (122 °F) 
SAE 10W-30  −18 °C (0 °F)  40 °C (104 °F) 
SAE 10W-40  −18 °C (0 °F)  50 °C (122 °F) 
SAE 15W-40  −9.5 °C (15 °F)  50 °C (122 °F)

S ·O ·S Services Oil Analysis


NOTICE

These recommendations are subject to change without prior notice. Contact your local AVSpare dealer for the most up to date recommendations.


AVSpare has developed a maintenance tool that evaluates oil degradation. the maintenance management also detects the early signs of wear on internal components. The AVSpare tool for oil analysis is called S·O·S oil analysis and the tool is part of the S·O·S Services program. S·O·S oil analysis divides oil analysis into four categories:

  • Component wear rate

  • Oil condition

  • Oil contamination

  • Identification of oil

These four types of analysis are used to monitor the condition of your equipment. The four types of analysis will also help you identify potential problems. A properly administered S·O·S oil analysis program will reduce repair costs and the program will lessen the impact of downtime.

The S·O·S oil analysis program uses a wide range of tests to determine the condition of the oil and the condition of the lubricated compartment. Guidelines that are based on experience and a correlation to failures have been established for these tests. Exceeding one or more of these guidelines could indicate serious fluid degradation or a pending component failure. A trained person at your AVSpare dealership should make the final analysis.


NOTICE

Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.


Refer to Special Publication, SEBU6251, "AVSpareCommercial Diesel Engines Fluids Recommendations" in order to obtain additional information about S·O·S Services oil analysis. You can also contact your local AVSpare dealer in order to obtain additional information about the S·O·S Services Oil Analysis program.

Fuel

Fuel Recommendations

Note: Dispose of the following waste according to all applicable regulations: water that has been drained from a fuel tank, sediment and debris.

  • Filter the fuel coming into the bulk storage fuel tank to 20 microns(c) absolute or less.

  • The filtration system on fuel tanks for bulk storage that are used for continuous filtration of stored fuel must be large. properly designed and properly grounded. The filter element/elements should be rated at a maximum of 5 microns(c) absolute. Refer to the recommendations from the manufacturer of the fuel filters in order to properly change the fuel filters.

  • Install water separators in two places: the device that dispenses fuel from the bulk fuel tank and the engine. Media that is made from wire mesh is not recommended.

  • Install and properly maintain four micron(c) absolute breather filters on both the engine fuel tank vent and on the bulk storage fuel tank vent. Breather vent filters that are filled with desiccant are also recommended in order to remove moisture from the air entering the fuel tank. Breather filters are typically changed at six month intervals. Breather filters that are filled with desiccant are typically changed when the filters are saturated. Refer to the literature that is included with the filter.

  • AVSpare strongly recommends the filtration of distillate diesel fuel through a filter with a rating of four microns(c) absolute or less. These filters should be located in two places: the device that dispenses fuel to the fuel tank for the engine and the device that dispenses fuel from the bulk storage tank. Using a series of filters is recommended.

In North America, a diesel fuel that is listed below generally meets the specifications: No. 1-D, No. 1-D S15 and No. 2-D in "ASTM D975" .

These fuels are distilled from crude oil. 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 Engine Fluids Recommendations" for additional information that relates to diesel fuel.

Cooling System

Coolant Recommendations


NOTICE

Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" 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 - (ELC) Extended Life Coolant or a commercial extended life coolant that meets the AVSpare EC-1 specification

Acceptable - (DEAC) Diesel Engine Antifreeze/Coolant 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: DEAC DOES NOT require a treatment with an SCA at the initial fill. Commercial heavy-duty coolant/antifreeze 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.

In stationary engine applications and marine 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. Refer to Special Publication, SEBU6251, "AVSpare Commercial Diesel Engine Fluids Recommendations" for additional information that pertains to coolants.

Note: Table 3 is a list of the coolants that are recommended and the service life (calendar) of the coolants. 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". To achieve this service life, the coolants must be properly maintained. The maintenance program includes S·O·S coolant analysis.

(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).

S·O·S Services Coolant Analysis

Testing the engine coolant is important to ensure that the engine is protected from internal cavitation and corrosion. The analysis also tests the ability of the coolant to protect the engine from boiling and freezing. S·O·S coolant analysis can be done at your AVSpare dealer. AVSpare S·O·S coolant analysis is the best way to monitor the condition of your coolant and your cooling system. S·O·S coolant analysis is a program that is based on periodic samples.

S·O·S Services Coolant Analysis (Level 1)

A coolant analysis (Level 1) is a test of the following properties of the coolant:

  • Glycol concentration for freeze protection and boil protection

  • Ability to protect from erosion and corrosion

  • pH

  • Conductivity

  • Visual analysis

  • Odor analysis

For information about performing this maintenance, refer to this Operation and Maintenance Manual, "Coolant System Coolant Sample (Level 1) - Obtain". For information about performing this maintenance, refer to this Operation and Maintenance Manual, "Maintenance Interval Schedule".

S·O·S Services Coolant Analysis (Level 2)

A coolant analysis ( Level 2) is a comprehensive chemical evaluation of the coolant. The S·O·S coolant analysis ( Level 2) has the following features:

  • Full coolant analysis (Level 1)

  • Identification of metal corrosion and of contaminants

  • Identification of buildup of the impurities that cause corrosion

  • Identification of buildup of the impurities that cause scaling

  • Determination of the possibility of electrolysis within the cooling system of the engine

For more information about the AVSpare S·O·S Oil Sampling program, see your AVSpare dealer.

Coolant Capacities

To properly maintain the cooling system, the total cooling system capacity must be determined. The total cooling system capacity will vary between individual installations. The total cooling system capacity can include the following components: engine, expansion tank, heat exchanger, radiator and piping.

Refer to the specifications that are provided by AVSpare or the OEM of the installation. Record the total cooling system capacity in the appropriate Table.
