NOTICE

These recommendations are subject to change without notice. Consult your local Cat dealer for the most up to date recommendations.


Note: Non-Cat commercial greases are as a group second choice greases. Within this grouping of second choice greases there are tiered levels of performance.


NOTICE

Cat does not warrant the quality or performance of non-Cat fluids and greases.


AVSpare provides a family of grease products that vary in performance from moderate to high performance. These greases service the entire line of Cat products in the wide variety of climates throughout the world. From this variety of Cat grease products, you can find a Cat grease that will meet or exceed the performance requirements for almost every machine that is produced by any Original Equipment Manufacturer (OEM), and for almost every machine application or equipment application.

Before selecting a grease product, the performance requirements must be determined. Consult the grease recommendations in your Operation and Maintenance Manual. Also, consult your Cat dealer for a list of greases that have the performance specifications and the available container sizes.

This grease chapter refers to the NLGI grade of the grease products offered by AVSpare. The National Lubricating Grease Institute (NLGI) classifies the greases per their consistency or hardness according to "ASTM D4950" and "SAE J310". The higher the NLGI grade the more firm the grease. The NLGI grade is an important classification for greases and it should be used along with other properties such as stability, corrosion resistance, viscosity, etc.

Note: Always choose grease that meets or exceeds the recommendations that are specified by the equipment manufacturer for the application.

Some work sites require the use of a single grease to fulfill the needs of all the equipment. Always choose a grease that meets or exceeds the requirements of the most demanding application. Remember that commercial products which barely meet the minimum performance requirements can be expected to produce the minimum life for the parts. It is not recommended to purchase grease products based on the lowest cost as the only consideration. Instead, use the grease that yields the lowest total operating cost. This cost should be based on an analysis that includes the improved product life, costs of parts, labor, downtime, and the cost of the amount of grease that is required.

Note: Certain Cat grease products are formulated with Molybdenum disulfide (MoS2 or “Moly”). The Moly used in Cat greases is of a technical fine grade. This size meets the special requirements of some rolling element bearings, joints, and other moving components of tight clearances.

Note: When the grease in a joint is changed from one type of grease to another or a grease from a different supplier is to be used, the general recommendation is to purge all of the old grease from the joint. Some greases are not chemically compatible. Consult your supplier in order to determine if the greases are compatible.

If in doubt, Purge!

Note: All Cat greases are “chemically” compatible with each other. Mixing of Cat greases will not result in an adverse chemical reaction. However, mixing of Cat greases might result in reduced performance.

Moderate Applications

The AVSpare family of greases includes several which are formulated for moderate applications of medium loads and speeds. These greases are formulated to provide optimal performance for these applications.

Cat Utility Grease

Cat Utility Grease is formulated for use in applications that have a low severity to a medium severity and moderate temperatures. Cat Utility Grease is a National Lubricating Grease Institute (NLGI) grade 2 grease. This grease is made with petroleum base oil and a lithium complex thickener.

Note: If the application calls for a utility grease and Cat Utility Grease is not available, consult the grease data sheets. Use a substitute that meets or exceeds the performance characteristics of Cat Utility Grease.

Cat White Assembly Grease

Cat White Assembly Grease is formulated for use in applications that have low to medium severity and moderate temperatures. This grease has been made extra tacky in order to hold gaskets, O-rings, and needle bearings to aid in the assembly of engines, transmissions, and other components. Cat White Assembly Grease is an NLGI grade 2 grease. This grease is made with a petroleum base oil and a lithium complex thickener.

Cat Prime Application Grease

Cat Prime Application Grease is formulated for use in applications with low severity to high severity at moderate temperatures. Cat Prime Application Grease is recommended for heavily loaded pin joints and high impact applications in machines such as track-type tractors, backhoe loaders and skid steer loaders.

Cat Prime Application Grease is an NLGI grade 2 grease. This grease is made with petroleum base oil and a lithium complex thickener. This grease has 3% Molybdenum diSulfide (MoS2 or “Moly”).

Note: If the application calls for a multipurpose grease with molybdenum and Cat Prime Application Grease is not available, consult the data sheets for the greases. Use a substitute that meets or exceeds the performance characteristics of Cat Prime Application Grease.

Severe Applications

The AVSpare family of greases includes several which are made with a Calcium Sulfonate Complex thickener. This type of grease is ideal for severe applications. These greases provide more load carrying (galling resistance), lower wear, longer working life, exceptional water washout, and resistance to corrosion.

Hammer Grease

Note: Refer to the Operation and Maintenance Manual for a particular hammer for recommendations that relate to greases for Cat Hammers.

Cat Extreme Application Grease

Cat Extreme Application Greases are specially formulated in order to protect all of the most heavily loaded joints in any Cat machine against galling, wear, and corrosion. This protection is sustained while operating in moderate temperatures and with wet or dry working conditions.

Cat Extreme Application Greases are available in NLGI grades 1, and 2. Cat Extreme Application Greases are made with special blends of petroleum base oils and Calcium Sulfonate Complex thickener. These greases also have 5% Molybdenum diSulfide (MoS2 or “Moly”) and performance enhancing additives.

A significant challenge exists in order to get grease to pump into the joints at low temperatures. Once the grease gets to the joint, the grease must have extremely high resistance to galling, wear, fretting, water washout, and corrosion in order to protect highly loaded joints adequately. Cat Extreme Application Greases are formulated with special blends of naphthenic petroleum base oils that have low pour points and will pump at lower temperatures. The ability to pump Cat Extreme Application Greases at lower temperatures means added insurance that all of the grease joints in the machine will be adequately lubricated even if the ambient temperature drops unexpectedly.

Even under severely loaded conditions, the grease should have a long working life. Inorder tomake greases that meet these greater demands, a Calcium Sulfonate Complex thickener with a properly blended naphthenic oil and/or a synthetic base oil is preferred. AVSpare uses these ingredients in Cat Extreme Application Greases.

Cat Extreme Application Greases also have 5% Moly, instead of the 0% to 3% that is found in most other greases. This additional Moly greatly improves the ability of the grease to protect parts from damage in applications with severe impact (slamming).

Cat Extreme Application Greases are also made to be extra tacky. In some applications, the film of grease must adhere to vertical surfaces. An example of this application is swing gears for excavators. Many conventional greases do not have enough of the tacky characteristic to keep the grease in place resulting in incomplete lubrication and premature wear or failure of components.

Note: If the application calls for Cat Extreme Application Grease and Cat Extreme Application Grease is not available, consult the data sheets for the grease. From these data sheets, use a substitute that meets the performance characteristics of Cat Extreme Application Grease.

Cat Extreme Application Grease-Desert

Cat Extreme Application Grease-Desert is formulated to protect the most severely loaded joints in Cat machines against galling, wear, and corrosion. This protection is sustained while working in moderate to hot temperatures with wet or dry conditions.

Cat Extreme Application Grease-Desert is an NLGI grade 2 grease. This grease is made with a high viscosity petroleum base and a Calcium Sulfonate Complex thickener. This grease also has 5% Molybdenum diSulfide (MoS2 or “Moly”) and tackifier.

As the temperature changes, Cat Extreme Application Grease-Desert experiences minimal change in viscosity and will maintain a thick lubricant film even at hot temperatures.

Cat Extreme Application Grease-Desert is made with a Calcium Sulfonate Complex thickener. Cat Extreme Application Grease-Desert provides the necessary protection against galling, wear, fretting, water washout, and corrosion. Cat Extreme Application Grease-Desert also has a long life. This grease will resist breakdown even when the application is under extremely heavy loads and with frequent oscillations. This protection is sustained while work is being done at moderate to hot temperatures under wet or dry conditions.

Cat Extreme Application Grease-Desert has 5% molybdenum instead of the 0% to 3% that is found in most other greases. This additional molybdenum greatly improves the ability of the grease to protect parts from damage in applications with severe impact (slamming).

Cat Extreme Application Grease-Desert is made to be extra tacky. In some applications, the film of grease must adhere to vertical surfaces. An example of this application is swing gears for excavators. Many conventional greases do not have enough of the tackifier to allow the grease to stay in place resulting in incomplete lubrication and premature wear or failure of components. In addition, many of these conventional greases do not have the performance, particularly at high ambient temperatures, to adequately protect the gear teeth in these applications.

Cat Extreme Application Grease-Desert prevents galling and wear in hot temperatures under extremely severe loads and conditions. In moderate temperatures, Cat Extreme Application Grease-Desert can be used in extremely severe applications if an improvement over Cat Extreme Application Grease is desired. Cat Extreme Application Grease-Desert can be used in applications that require the lubricant to last for long periods of time because this grease has an extremely high performance and long life.

Note: If the application calls for Cat Extreme Application Grease-Desert and Cat Extreme Application Grease-Desert is not available, consult the data sheets for the grease. From these data sheets, use a substitute that meets the performance characteristics of Cat Extreme Application Grease-Desert.

Cat Extreme Application Grease-Arctic (Semi-Synthetic)

Cat Extreme Application Grease-Arctic is formulated to protect the most heavily loaded joints in AVSpare machines against galling, wear, and corrosion. This grease resists breakdown even under extremely heavy loads and/or in applications with frequent oscillations. This grease provides protection that will be sustained for long periods of time and in wet or dry conditions. This protection is sustained, while work is being done in moderate temperatures and in low temperatures that may reach −50° C (−58° F). In moderate temperatures, Cat Extreme Application Grease-Arctic can be used in the application if the compartment is sealed tightly to contain the grease

Cat Extreme Application Grease-Arctic is available in NLGI grade 0. This grease is made with a semi-synthetic base oil that has a low viscosity for optimal cold-weather performance. The performance is enhanced with 5% Molybdenum diSulfide (MoS2 or “Moly”) and tackifier.

Cat Extreme Application Grease has low viscosity and semi-synthetic base oil. Hence, as the temperatures drop, this grease has minimal change of viscosity and continues to flow easily. Cat Extreme Application Grease-Arctic pumps easily at extremely low temperatures. In fact, CatExtreme Application Grease-Arctic NLGI grade 0.5 can be pumped through standard automatic lubrication systems that are machine mounted and at temperatures down to −50° C (−58° F). This means that the grease can be pumped through long unheated lines and into the required joints.

Cat Extreme Application Grease-Arctic has 5% of molybdenum instead of 0% or 3% that is found in most of the other greases. This additional molybdenum greatly improves the ability of the grease in order to protect parts from damage in applications with severe impact (slamming).

Cat Extreme Application Grease-Arctic is made to be extra tacky. In some applications, the film of grease must adhere to the vertical surfaces. An example of this application is swing gears for excavators. Many conventional greases do not have enough tackifier to adhere well to the vertical surfaces. This ability is necessary in order to protect the gear teeth in these applications adequately.

Cat Extreme Application Grease-Arctic may be used in applications that require the lubricant to last for long periods of time. This grease has an extremely high performance and also has a long life.

If the application calls for Cat Extreme Application Grease-Arctic and no Cat Extreme Application Grease-Arctic is available, consult the data sheets for the grease. Use a substitute that most closely meets the performance characteristics.

Cat Ball Bearing Grease

This grease is recommended for applications that utilize roller bearings and ball bearings at low to moderate loads and at high speed. Typical applications for this grease are electric motors, alternators, and constant velocity (CV) joints for automotive products. Cat Ball Bearing Grease is an NLGI grade 2 grease. This grease is made with petroleum base oil and polyurea thickener.
