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:

Important Safety Information



Illustration 1g02139237

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 2g00008666

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.

------ WARNING! ------

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.


------ WARNING! ------

Hot oil and components can cause personal injury.

Do not allow hot oil or components to contact skin.


------ WARNING! ------

Personal injury or death can result from not following the proper procedures.

To avoid the possibility of injury or death, follow the established procedure.

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 3g00928732

Use the "FWD" key to shift the transmission to FORWARD 1.

Use the "REV" key to shift the transmission to REVERSE 1.

Use the "8" key to turn off the transmission harness, and use the "8" key to turn on the transmission harness.

Note: The "8" key is used to test the latching circuit. This function will simulate a power failure at the ECM.

Use the "6" key to simulate an open circuit to a rear planetary clutch.

Use the "4" key to simulate an open circuit to a front planetary clutch.



Illustration 4g00878493

Use the "N" key to shift the transmission to NEUTRAL.



Illustration 5g00928736

Use the "UP CURSOR" key to upshift the transmission to the next higher gear range.



Illustration 6g00928740

Use the "DOWN CURSOR" key to downshift the transmission to the next lower gear range.

    NOTICE

    Never rotate the transmission in the state of no clutch neutral, rear box neutral, or multiple clutch tie up. Operating the transmission in any of these conditions can damage internal parts of the transmission.

    The transmission must be operated with the correct clutches engaged or disengaged to prevent damage to the transmission.


  1. Warm the supply oil in the auxiliary oil tank to (125 °F). Refer to the documentation that is provided with your equipment.

    Note: Multigrade oil is NOT permitted.

  2. The input rotation MUST BE 0 rpm.

  3. Adjust the input flow for the transmission control to 120 ± 4 L (31 ± 1 US gpm).

  4. Adjust the input flow for the transmission lubrication oil to 245 ± 4 L (65 ± 1 US gpm).

  5. Verify test points with the values in Table 9 before proceeding with the test.

    Note: Tooling (P) has been programmed to ensure that the transmission is shifted sequentially into gear ranges. The functionality of some of the input keys has been changed to ensure the requirements of this procedure. Refer to Special Instruction, "Programming Features" for further information.



    Illustration 80g02720621

  6. With the transmission in the NEUTRAL position, rotate the input shaft in a counterclockwise direction. Adjust the input rotation to 400 ± 10 rpm. Make all shifts at 400 ± 10 rpm during this test procedure.

    Note: The input shaft will be rotated in a counterclockwise direction for the duration of this test. The direction is determined as you face the drive motor of the test bench.

    Use Tooling (P) to shift the transmission through all directions and through all speed ranges to eliminate air from the transmission controls.

  7. Verify that the active clutches are correct for each gear range. Refer to Table 5.

    Note: The active clutches must match Table 5 before proceeding with the test.
