Recommended Grease
Cat MPGM (Multipurpose Grease w/Moly)
Cat MPGM is an NLGI grade 2 grease. This grease is made with petroleum base oil and a lithium complex thickener. This grease also has 3% Molybdenum diSulfide (MoS2 or moly). Cat MPGM is formulated for use in applications with low severity to high severity at moderate temperatures. In addition, the Moly in Cat MPGM is a special grade that has a median particle size of 3 microns in order to meet the special requirements of some rolling element bearings. Cat MPGM is recommended for heavily loaded pin joints, and high impact applications in machines such as Track-Type Tractors, Backhoe Loadersand Skid Steer Loaders.Cat MPGM meets the NLGI certification of "GC-LB". (This certification relates to extended service intervals in automotive chassis points and in wheel bearings with disc brakes in automobiles, vans, and light trucks.)Cat MPGM grease will pump through centralized autolube systems at ambient temperatures down to −18 °C (0 °F). Cat MPGM grease will perform well in medium applications to high severity applications up to 41 °C (106 °F). In less severe applications, this grease can be used at higher temperatures.Note: If the application calls for a multipurpose grease with molybdenum and Cat MPGM is not available, consult the data sheets for the greases. Use a substitute that meets the performance characteristics of Cat MPGM or use a substitute that exceeds the performance characteristics of Cat MPGM.Severe ApplicationsCaterpillar has greases which are made with a Calcium Sulfonate Complex thickener. This type of grease is necessary for more severe applications. These greases provide more load carrying (galling resistance), lower wear, longer working life, exceptional water washout, and resistance to corrosion.Note: For further information, refer to Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations", "Lubricating Grease".
