Refer to Operation and Maintenance Manual, General Hazard Information for information that pertains to Containing Fluid Spillage.
Before you obtain an S-O-S oil sample, operate the machine until the oil is warm and the oil is well circulated. Then obtain the S-O-S oil sample.
There are two ways to obtain SOS oil samples. The following methods are listed in the order that is preferred:
• Use an in-line sampling valve for pressurized oil systems. • Use a sampling gun that is inserted into the sump.
Use of the in-line sampling valve is the preferred method. This method provides samples that are less likely to be contaminated. Whenever you obtain the samples,
obtain the samples from the same point. This makes the samples more representative of the oil that is in the system.
In-line sampling valves cannot be used on nonpressurized oil systems such as differentials and final drives. Use of the sampling gun is the preferred method for
nonpressurized oil systems.
Refer to the Operation and Maintenance Manual, Maintenance Interval Schedule for the proper interval.
The SOS oil analysis is composed of four basic tests: • Wear metal analysis
• Infrared analysis for oil condition • Tests for contamination of the oil by fuel, by water, andor by antifreeze
• Particle Count for hydraulics, transmissions and other gear compartments Consult your Caterpillar Dealer for complete information and assistance about the S-O-
S oil analysis program.
4. Sampling Interval and Location of Sampling Valve
Take the oil samples as close as possible to the standard intervals. In order to receive the full value from SOS oil analysis, you must establish a consistent trend of data. In
order to establish a pertinent history of data, perform consistent samplings that are evenly spaced

5. Desert Gold CPG
Caterpillar Desert Gold is a heavy duty, premium synthetic, extreme pressure lubricating grease developed for the most extreme operating environments. Desert
Gold is formulated with a high viscosity, synthetic base fluid, polymers and molybdenum disulfide, as well as a high viscosity index and high dropping point.
Caterpillar Desert Gold will protect equipment against heavy shock loads. Desert Gold protects against corrosion in extreme heat, in moist conditions, or in dusty conditions.
This product has excellent characteristics of adhesion and of stability. Caterpillar Desert Gold provides longer protection than other greases. Caterpillar Desert Gold is
an environmentally friendly grease which does not contain antimony, sulfur, barium, zinc, lead, or phosphorous. Normal operating temperatures are -6 to 230°C 21 to
450°F. Caterpillar Desert Gold can operate at higher temperatures for shorter time periods. Caterpillar Desert Gold has additional extreme pressure protection for highly
loaded pin joints.
6. Arctic Platinum CPG
Caterpillar Arctic Platinum is a super-premium extreme pressure lubricating grease developed for lubrication in below zero temperatures to moderate operating
temperatures. Arctic Platinum is available in grades 000, 00, 0, 1, and 2 to ensure flow in central lube systems in a variety of ambient temperatures from -60 to 18°C -76 to
65°F. Caterpillar Arctic Platinum has a high drop point and contains five percent molybdenum disulfide for protection against extra heavy loads. Arctic Platinum
provides excellent protection against corrosion and against oxidation. Caterpillar Arctic Platinum is an environmentally friendly grease which does not contain antimony, sulfur,
barium, zinc, or phosphorous.
Caterpillar Arctic Platinum is designed for long life lubrication of horizontal pivot and lower link bearings, of steering cylinders, of kingbolt bearings, of upper hitch link
bearings and of ejector carrier roller bearings. This grease is extra tacky for retention on excavator carbody bearings. Caterpillar Arctic Platinum has additional extreme
pressure protection for highly loaded pin joints
