Services Position on Machine Profiles
Machine Profiles were documents that contained specific information on Caterpillar machine models and engines. The primary purpose of these
documents was to provide the S·O·S Services interpreter with specifications and guidelines for cooled and lubricated compartments on Cat equipment. Machine Profiles were last published about fifteen years ago. At that time, this information was typically found in many different paper documents.
Most of the information that was in the Machine Profiles can be gathered from a variety of accurate electronic sources. The chart on the following page shows a list of items that were covered by the Machine Profiles. For each item in the list, there are two or three sources available to obtain the desired information. All of the primary and secondary sources of information are electronic files. These files are available to Caterpillar dealer personnel.
Three of these items may require additional intervention: Oil Transfer,
Uncommon Contaminants, and Uncommon Wear Elements. Problems like these three are generally rare. Also, these problems are usually confined to a small population of machines or engines. If the interpreter suspects one of these unusual problems, a Community Discussion can be initiated on the S·O·S
Services Knowledge Network. Community Discussion items are responded to by other dealers, and by S·O·S Services personnel at Caterpillar.
Ultimately, it may be necessary to contact the dealership‘s Techni cal
Communicator (TC) and request assistance. The TC can search the Dealer Solutions Network (DSN) for similar problems. If a similar problem is not found, the TC can submit a DSN request for information. This is the most efficient way to report these types of problems. If the DSN discovers a significant product problem, additional Caterpillar resources will be summoned to contain and solve the problem.
The use of these information sources surpasses the support that was provided by Machine Profiles. The electronic data sources contain more information and the information has a higher degree of accuracy. Additionally, the DSN is in place to support the dealership, when new or unusual problems occur in Cat equipment. The DSN can bring these problems to the forefront. Service engineers and product engineers will then take action on these problems.
Therefore, S·O·S Services will not be producing new Machine Profiles. Fifteen years ago, they met a need in the program; now these needs can be met with a variety of new and improved sources.

UFM INTERPRETATION SYNOPSIS
SOSsm Services will now be reporting FT-IR results in a new format. The results for soot, oxidation,
sulfation, and nitration will be unitless whole numbers (UFM – Unsubtracted FT-IR Method number) that
no longer represent % Allowable values. Please note that this new method is still to be utilized as a trending module. There will be samples and oil types that do not fit this model. Please refer to the technical paper ―Un-Subtracted FTIR Methodology for SOSsm Services‖ for further details. Also note
that all information in this document was gathered utilizing a Perkin Elmer Oil Express FT-IR with Spectrum One software and the SOSsm Services Manager laboratory information management
software.
Shown below is a chart with comparisons for new soot values and the corresponding absorbance, %T, and % allowable values. Since soot is only the measure of light passage through a sample, there is a
direct relationship between the absorbance value obtained at the instrument level and the resulting UFM, %T, and % allowable values.

The UFM values for oxidation, sulfation, and nitration are not directly related to the absorbance value obtained at the instrument level. Absorbance is a single – point measurement, whereas our new method
of FT-IR analysis actually measures the peak area in a specific wavenumber range. Because this new measurement is no longer a single point, we are not able to directly correlate previous % allowable values with the UFM values you will see on your reports. Shown above is a table summarizing the values for oxidation, sulfation, and nitration to be used as guidelines during oil interpretation. Please refer to the technical paper listed above for more details.
The water screen information comes out of the Spectrum One software as Water Petroleum Lube. The value in this area is also a UFM number, and does not represent % water in the sample (see above table). Also, the % water and corresponding UFM number do not exhibit a linear relationship. Therefore, you cannot extrapolate % water data using the UFM number. A sample with a water petroleum lube UFM number of less than 31 will be negative for water screen. SOSsm Services
Manager will assign a water test to this sample and complete the test by entering a negative value. A sample with a water petroleum lube UFM number of 31 to 34 will indicate a possible f or water screen, SOSsm Services Manager will assign a water test, and it will remain incomplete until a technician
performs a physical confirmation of presence of water and enters the result. A sample with a water petroleum lube UFM number of 35 or greater will indicate a probable for water screen, SOSsmServices

Interpretation Guidelines for Fuel Dilution Results in Caterpillar Off-Highway Diesel Engines
Two Caterpillar service documents were released to address the subject of fuel dilution in off-highway diesel engines. These documents are a Special
Instruction REHS3007, and a Technical Information Bulletin TIBU4910. These service documents provide test guidelines for the oil viscosity test and the GC fuel dilution test. These documents do not provide interpretation guidelines for
S·O·S Services interpreters at the dealership.
This document provides a series of interpretations that can be used when relaying fuel dilution recommendations to a customer. Use of these interpretations will provide the customer with a clear understanding of the
problem, and the recommended action. These interpretations will also provide a level of commonality between Cat dealers. This is especially important to

problem, and the recommended action. These interpretations will also provide a level of commonality between Cat dealers. This is especially important to
customers that use more than one dealer for their oil analysis business.
These example interpretations are written with the assumption that the customer is sampling at a recommended oil change interval. If the sample has very few hours of operation, or if the sample has been run for an extended period of time, the interpreter may need to adjust the recommendation and change the alert level. In other words, these interpretations may not exactly fit every scenario; however, they do provide a common framework that addresses the most
common sample results. The interpreter should always use their experience and equipment history to make the best recommendation.

Modified Stray Current Test
The standard test for stray current measures the current (AC & DC) from (a) coolant to ground of battery, (b) from top of radiator, near clamp, to battery ground, (c) the outside of the engine block to the battery ground.
This is done under the following conditions: (1) the engine and all accessories off, (2) the starter engaged – accessories off, (3) all accessories turned on.
If there is a stray current only when more than one accessory is turned on, turn off the accessories sequentially until the stray current disappears. This will indicate the source of the stray current. This test, as designed, will determine a normal stray current (positive for a negative ground system & negative for a positive ground system) where the batter ground is the system ground for all component systems.
There is no common ground in many of our power generation applications, which allows the possibility (with these floating grounds) of a positive or negative stray current (with

There is no common ground in many of our power generation applications, which allows the possibility (with these floating grounds) of a positive or negative stray current (with respect to either the engine ground, radiator ground or a true earth ground).
If a positive stray current exists (normal stray current condition), the metal acts as an anode and serious corrosion occurs at the anode (ex: high iron seen in coolant analysis report). If a negative stray current exists (if all normal negative grounds were tied together this condition would be impossible), the metal would act as a cathode and no corrosion would occur. However, the reduction of the nitrite and nitrate in the coolant could occur, which enables the production of ammonia. Ammonia can destroy the radiator, oil cooler cores, or any other copper alloy component it contacts in short order.
It is necessary to check the voltage on the coolant with respect to the battery ground, earth ground, and the block, and to determine if the current is positive or negative. It is also necessary to check for any potential difference between the block, radiator, battery ground, and the earth ground.

Coolant Analysis Overview
Foreword
The Importance of Coolant
Everyone understands the importance of oil, but another key fluid in Caterpillar engines, machine design and maintenance is the engine coolant.
How critical is it?
An estimated 50% of all engine failures or poor performance incidents are associated with cooling system problems. For this reason, Caterpillar developed the S•O•S Coolant Analysis program. S•O•S Coolant Analysis is recommended for cooling systems, regardless of type of coolant used. This includes Caterpillar Extended Life Coolant (ELC) systems or standard coolant systems, including Caterpillar Diesel Engine Antifreeze/Coolant (DEAC).
Coolant requirements for diesel engines are more severe than for automotive engines.
Diesel engines are designed to operate at higher temperatures and higher energy levels than engines in cars and small trucks. Today‘s heavy diesels produce a tremendous amount of power from a small package. Additionally, most of today ‘s Caterpillar products rely on the engine cooling system to absorb heat from the engine, transmission, and hydraulic oils. These factors increase the requirements and demands placed on the cooling system.
Used coolant disposal requirements have become more stringent and expensive. Used coolant disposal must be done in accordance with local, state, and federal laws. Customers may be extending coolant drain intervals, recycling coolants and reconditioning coolants to reduce disposal costs.
For all of the above critical reasons, S•O•S Coolant Analysis is highly recommended to achieve optimum performance and the full life designed into today ‘s machines and engines.

There are three primary goals of the S•O•S Coolant Analysis program:
1. Fluid Condition – Indicates if coolant use can be continued or if it needs to be discarded and replenished with new. 2. Component Failure – Indicates when
an engine or cooling system failure has occurred. Such failures include a blown head gasket, a corroded ground, or a blocked coolant line.
3. Life Cycle Management – Provides
indications of shortcomings in equipment operational practices and maintenance procedures.

Coolant Analysis
The chemistry of diesel engine coolant is complex. The chemical changes the coolant experiences in service are even more complex and variable. The objective of the S•O•S Coolant Analysis program, as with S•O•S Oil Analysis, is to help assure that Caterpillar machines achieve their full design life while providing maximum productivity with the lowest expense. To some observers, Coolant Analysis may seem to focus more on the
chemical changes within the coolant, and therefore coolant condition; whereas Oil Analysis, while considering oil condition,
appears to focus more on contamination of the oil. However, the objective is the same for both programs: to determine if a problem exists and to determine and correct the cause.
the former Diesel Engine Coolant/Antifreeze (DEAC) to a significantly superior product, Caterpillar Extended Life Coolant (ELC). The advantages of ELC over DEAC in terms of both protection to the cooling system and in cost of operation are great. However, cooling systems require periodic testing to assure that they are operating adequately.
There are two primary reasons for
deterioration of coolant in diesel engines: • Improper maintenance practices
(topping up with only water, SCA added to ELC, over/under
concentration of SCA‘s etc.)
• Cooling system problems (localized overheating, exhaust gas entry,
electrolysis, etc.)
Regardless of the type of coolant, periodic analysis of samples should be a consistent part of any maintenance program.
ELC is superior to DEAC in all respects. Although ELC is initially more expensive, its
longer life coupled with the fact that it does not require maintenance to add SCA results in a cost per operating hour that is half (or less) than that of DEAC.
