SPECIAL PURPOSE GREASE SPG
1. Bearing Lubrication SPG
Bearing Lubricant is a NLGI No. 2 lubricating grease with a polyurea thickener. This grease is recommended for high temperature antifriction bearings in the following
applications: electric motors, alternators, fan drives, starters and generators. The Bearing Lubricant SPG has an effective operating range of -29 to 177°C -20 to
350°F.
2. Water and Temperature Resistant Grease SPG
The Caterpillar Water and Temperature Resistant Grease is designed for use whenever the following conditions are a concern: water washout, severe corrosion and
high operating temperatures. The grease provides extreme pressure, antiwear, oxidation, and corrosion protection without using barium, zinc, antimony, phosphorous,
lead type additives, or sulfur type additives. Caterpillar Water and Temperature Resistant Grease is a grease that is friendly to the environment. The Water and
Temperature Resistant Grease has excellent shear stability. The grease also resists breakdown in the presence of water. The Caterpillar Water and Temperature Resistant
Grease behaves well in marine applications, in washer equipment bearings, in automotive equipment, in agricultural equipment, in industrial applications, and in
construction equipment. This product meets the NLGI certification of GC-LB. Normal operating temperatures for this product are -40 to 204°C -40 to 400°F.
3. Re-refined Base Stock Oils
Re-refined base oils are acceptable for use in Caterpillar engines and in Caterpillar machines if these oils meet the performance requirements that are specified for a
particular compartment. Each compartment has lubrication requirements and lubrication specifications in order to ensure proper lubrication and life of the system.
Re-refined base oils can be used exclusively in finished oil or in a combination with new base oils. The US military specifications and the specifications of other heavy
equipment manufacturers also allow the use of re-refined base oils that meet the same criteria.
The process that is used to make re-refined oil should adequately remove all wear metals that were in the used oil and all additives that were in the used oil. The vacuum
distillation and the hydrotreating of used oil are utilized in the process that creates re- refined oil. Filtering is inadequate for the production of high quality, re-refined base oils
from used oil.

4. After-Market Oil Additives
Caterpillar does not recommend the use of aftermarket additives in oil. It is not necessary to use aftermarket additives in order to achieve the machines maximum
service life or rated performance. Fully formulated, finished oils consist of base oils and of commercial additive packages. These additive packages are blended into the base
oils at precise percentages in order to provide finished oils with performance characteristics that meet industry standards.
There are no industry standard tests that evaluate the performance of aftermarket additives in oil. There are also no industry standard tests that evaluate the compatibility
of these aftermarket additives in a finished oil. Aftermarket additives may not be compatible with the finished oils additive package, which could lower the performance
of the finished oil. The aftermarket additive could fail to mix with the finished oil. This could produce sludge. Caterpillar discourages the use of aftermarket additives in
finished oils.
To achieve the best performance from a Caterpillar engine, obey the following guidelines
1. Select the proper Caterpillar oil or a commercial oil that meets the specifications of the compartment.
2. To find the correct viscosity grade for your machine, see the table in the Operation and Maintenance Manual, Lubricant Viscosities information.
3. At the specified interval, service the engine or service the compartment. Use new oil and install a new oil filter.
4. Perform maintenance at the intervals that are specified in Operation and Maintenance Manual, Maintenance Interval Schedule.
5. Lubricating Grease
Caterpillar provides a number of greases in order to cover a variety of applications and extreme temperature conditions. See your Caterpillar dealer or see Special
Publication, PECP4025, One Safe Source for the part numbers.
Note: Some greases may not be used with other greases. When you use commercial grease, make sure that the grease is compatible with the grease that is currently used
in your system. If you have any questions concerning the compatibility of your grease, consult your supplier.
6. Multipurpose Greases
Multipurpose Lithium Complex Grease MPGL
Multipurpose Lithium Complex Grease is a National Lubricating Grease Institute NLGI No. 2 general purpose lithium complex grease for medium duty applications.
This product has good characteristics at high temperatures such as a dropping point
