Illustration 71 A grease gun is stored in the radiator compartment on the left side of the machine.
Remove the grease gun from the holder. After you grease the machine, push the grease guns handle inward. Clean the grease gun nozzle. Place the grease gun back
into the holder.

COLD WEATHER LUBRICANTS
When you start an engine in ambient temperatures below -20°C —4T or when you
operate a machine in ambient temperatures below -20C -4T, use base oils that can flow in low temperatures. These oils have viscosity grades of SAE 0W or of SAE 5W
MPGL meets the requirements for extended service intervals of automotive chassis points and for extended service intervals of wheel bearings with disc brakes in
automobiles, in vans, in taxi fleets, and in light trucks. This product meets the NLGI certification of GC-LB. Normal operating temperatures for this product are -28 to
149°C -18 to 300°F. This product is also available as a white lithium complex grease.
1. Multipurpose Lithium Complex Grease with Molybdenum MPGM
MPGM is a NLGI No. 2 general purpose lithium complex grease that is used for light- duty applications and for medium duty applications. The MPGM is strengthened with a
molybdenum disulfide and with a high molecular weight polymer. These additives strengthen the capabilities of lubrication. The additives also increase the protection to
the parts. The MPGM is strengthened for extra lubrication and for extra protection. MPGM contains unleaded additives. MPGM also contains antiwear inhibitors, inhibitors
for oxidation, and corrosion inhibitors that are for protection and lubrication in many environments. The MPGM is formulated with a high viscosity base fluid and a polymer
additive.
The MPGM has the following features: • Protection against water washout
• Increased retention • Resistance to heavy loads

This product is recommended for the following uses: heavily loaded pin joints, journal bearings, heavy-duty automotive applications, agricultural, industrial, steel mill, mining
and off-highway equipment. This product meets the NLGI certification of GC-LB. Normal operating temperatures for this product are -28 to 149°C -18to300°F.
Note: If MPGM is not available, use a multipurpose type grease which contains three to five percent molybdenum.
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.
