Engage the parking brake and shift the transmission to the NEUTRAL position.
Start the engine. Warm the transmission oil to normal operating temperature of approximately 76 to 112°C (168 to 234°F).
Fully depress the right side service brake pedal. Hold the right service brake pedal in the depressed position for the duration of the test. Ensure that the parking brake is applied.
To ensure that the transmission oil does not overheat, do not keep the torque converter in a full stall condition for more than 30 seconds. After the torque converter stall test, reduce the engine speed to low idle. In order to cool the oil, move the transmission control to the NEUTRAL position and run the engine between 1200 rpm and 1500 rpm.

Allow the engine rpm to stabilize. Then, observe the tachometer and record the result.The correct stall speed for the 814F/F Series 2 Wheel Dozer, the 815F/F Series 2 Soil Compactor, and the 816F/F Series 2 Landfill Compactor is 2090 65 rpm.Stall speeds that are low indicate incorrect engine performance. Stall speeds that are high indicate incorrect transmission performance or incorrect performance of the torque converter. If you must repeat the test, keep the transmission in neutral and wait for two minutes between tests.ReferenceFor additional information about the Caterpillar Monitoring System, refer to Service Manual, SENR1394, "Caterpillar Monitoring System".ReferenceFor additional information about troubleshooting the transmission and the torque converter, refer to the Service Manual modules Troubleshooting, "Torque Converter" for the machine that is being serviced.
