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).
Water and Temperature Resistent Grease
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).
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 rerefined oil. Filtering is
inadequate for the production of high quality, re-refined base oils from used
oil.
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 machine's 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 oil's 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:
- Select the proper Caterpillar oil or a commercial oil that meets the specifications of the compartment.
- To find the correct viscosity grade for your machine, see the table in the Operation and Maintenance Manual, "Lubricant Viscosities" information.
- At the specified interval, service the engine or service the compartment. Use new oil and install a new oil filter.
- Perform maintenance at the intervals that are specified in Operation and Maintenance Manual, "Maintenance Interval Schedule".
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.
Multipurpose Greases
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 over 260°C (500°F). MPGL contains
unleaded extreme pressure additives and antiwear inhibitors that provide extra
protection in the following applications:
- Construction
- Agricultural
- Automotive
Final Drive Oil and Swing Drive Oil
Applications:
- Power Shift Transmissions, Direct Drive Transmission, and Winches
- Final Drives: Track Type Tractors, Pipelayers, Skidders, Loaders, and Track Type Excavators
- Differentials and Final Drives: Wheel Tractors, Loaders, Skidders, Compactors, Motor Graders, Off-Highway Tractors, and Trucks
