Unauthorized use of this document or the proprietary processes therein without permission may be violation of intellectual property law. Information contained in this document is considered Caterpillar: Confidential Yellow.
This special instruction contains the necessary information that is required to bench test-specific transmission arrangements. Refer to Table 2 for the correct arrangements. Bench testing the transmission ensures correct assembly and operation of the component. Rotating a transmission provides the most conclusive evaluation. This procedure allows the dealer to ensure that the transmission will operate properly in the machine. The specifications in this guideline are specific to bench testing the component. Every effort has been made to provide the most current information that is known to Caterpillar. Continuing improvement and advancement of product design might have caused changes to your product which are not included in this publication. This guideline must be used with the latest technical information that is available from Caterpillar.
For questions or additional information concerning this guideline, submit a form for feedback in the Service Information System. To address an urgent issue, use the following resources to communicate your request to Caterpillar Repair Process Engineering:

Canceled Part Numbers and Replaced Part Numbers
This document may include canceled part numbers and replaced part numbers. Use NPR on SIS for information about canceled part numbers and replaced part numbers. NPR will provide the current part numbers for replaced parts.
Important Safety Information
Illustration 1 | g02139237 |
Follow all safety warnings. Most accidents that involve product operation, maintenance, or repair are caused by failure to observe safety warnings. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. Personnel must be properly trained to perform maintenance, repair, or operate any machine. Safety precautions and warnings are provided this instruction and on Caterpillar products. These warnings should be observed before performing any procedures. Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The warnings in this publication and on the product are not all inclusive.
The hazards are identified by the “Safety Alert Symbol” which is followed by a “Signal Word” such as “DANGER”, “WARNING, or” “CAUTION”. The “WARNING” Safety Alert Symbol is shown in illustration below.
Illustration 2 | g00008666 |
This safety alert symbol means:
Pay Attention!
Become Alert!
Your Safety is Involved.
The message that appears under the safety alert symbol explains the hazard.
Operations that may cause product damage are identified by "NOT" labels on the product and in this publication.
Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The safety information in this document and the safety information on the machine are not all inclusive. Determine that the tools, procedures, work methods, and operating techniques are safe. Determine that the operation, lubrication, maintenance, and repair procedures will not damage the machine. Also, determine that the operation, lubrication, maintenance, and repair procedures will not make the machine unsafe.
The information, the specifications, and the illustrations that exist in this guideline are based on information which was available at the time of publication. The specifications, torques, pressures, measurements, adjustments, illustrations, and other items can change at any time. These changes can affect the service that is given to the product. Obtain the complete, most current information before you start any job. Caterpillar dealers can supply the most current information.
Collecting the Test Data
Since conditions vary for each test bench, use the data that is collected from your test bench. The collected data is used to compare test results. The data should be collected and maintained by the operator.
Data from each transmission arrangement is collected and stored. Averages from each transmission arrangement are often used to compare values on portions of transmission tests. Always compare data that is collected from the same transmission arrangement that is being tested. Averages for the last 20 transmission arrangements should be maintained.
Personal injury or death can result from escaping fluid under pressure. Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. Always use a board or cardboard when checking for a leak. |
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. |
Personal injury or death can result from not following the proper procedures. To avoid the possibility of injury or death, follow the established procedure. |
Tools Needed
Note: The required tools that are listed in Table 3 were used to develop this test procedure. For additional information about tooling, consult Caterpillar Service Tools Division (800) 542-8665.

Software Requirement
The 9U-7500 Electronic Control Group requires a custom software update to test the transmission for a 797 and 797B Off-Highway Truck. This software will not be included with the Software Subscription, NETG5021, "9U-7500 Transmission Analyzer II Program". You must order Software Update, NETG5036, "797 and 797B Transmission Analyzer II Program".
Programming Features
The 797 and 797B transmission must be shifted sequentially through the gear ranges.
The 9U-7500 Electronic Control Group has been programmed to ensure that the transmission will be shifted sequentially through the gears. The functionality of some of the input keys has been changed to ensure the requirements of this procedure. The following examples are typical screen displays.
The available keys will be listed across the bottom of the active display screen.
Illustration 3 | g00928732 |
