This document contains the necessary information that is required to bench test a specific transmission arrangement. 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. Testing allows the dealer to ensure that the transmission will operate properly in the machine. The specifications in this document 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 document must be used with the latest technical information that is available from Caterpillar..

Important Safety Information

Show/hide table




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.

Show/hide table




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 "NOTICE" 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 document 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.

Show/hide table

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.

Show/hide table

Hot oil and components can cause personal injury.

Do not allow hot oil or components to contact skin.

Show/hide table

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: Pressures will be sensitive to tooling setup. The diameter of the hose, the diameter of a fitting, and extra filtering can affect pressure. The required tools that are listed in Table 3 were used to develop this test procedure. These tools are suggested and may very depending on availability and bench configuration were used to develop this test procedure.

Test Procedure

Harness Test

Make sure that the Tooling (W) is properly connected.
Use Tooling (X) to perform the harness test.
Record the values in Table 7.

Start Checks

Refer to Testing and Adjusting, RENR8454, "140M and 160M Motor Graders Power Train" for the correct adjusting procedures.

If you are using SAE 10W oil, warm the oil to 50 °C (125 °F). If you are using Mobil DTE11 oil, warm the oil to 34 °C (95 °F). Maintain this temperature for the duration of the test.

Test Bench Rotation Direction
With the transmission in the NEUTRAL position, rotate the input shaft in a counterclockwise direction. Adjust the input rotation to 800 rpm.
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.
Note: An input speed of at least 800 rpm must be maintained for the duration of the test. This speed will prevent the engagement of the parking brake.
Check the Pump Flow and the Main Relief Pressure. Compare the results with Table 4.

Shift the transmission through all gears to eliminate air from the transmission controls.
Check for lockup or excessive drag in all gears.

Cooler Bypass Check

Shift the transmission to the NEUTRAL position.
Adjust the input speed from 800 rpm to 2100 rpm.
Use Tooling (K) to slowly restrict Cooler Flow (Lube In) until Cooler Flow (Lube In) starts to drop.
Cooler bypass should occur at a delta pressure of 517 ± 34 kPa (75 ± 5 psi) (Cooler Pressure — Lube Pressure).
Note: Bypass may not occur at the cracking of the bypass valve. You may need to close Tooling (K) more to achieve full shifting of bypass valve.
Record and verify Pump Flow, Lube Flow (Cooler Flow), Cooler Bypass Valve Pressure in Table 19.
Open Tooling (K).
Stop the input rotation.

Contamination Control

Take an oil sample of the test bench oil supply. Oil contamination sample must meet ISO 16/13 standards.
Record the results in Table 20.
Remove the transmission from the test bench if the test bench oil supply is within specifications.
