Personal injury or death can result from sudden machine movement.Sudden movement of the machine can cause injury to persons on or near the machine.To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.
Move the machine to a level area that is clear of personnel.
Place the machine in position against a solid, stationary object such as a loading dock. Engage the parking brake.
Move the transmission direction control switch to the NEUTRAL position. Apply the parking brake.
If the torque converter stall test is done indoors, make sure that there is adequate ventilation for the exhaust.
Start the engine. Note: 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.
Make sure that the transmission oil is at normal operating temperature.
Press operator mode switch until digital display of the monitor displays the rpm of the engine. Note: Refer to Operation and Maintenance Manual, SEBU8540, "525D, 535D, 545D, and 555D Wheel Skidders " for the operation of the monitor system.
Apply the service brakes firmly and keep the brakes applied through Step 11.
Disengage the parking brake. Shift the transmission direction control switch and the transmission upshift switch to fifth speed forward and fully depress the accelerator pedal. Allow the engine rpm to stabilize. Then, observe the rpm on the display.
Operate the engine at 2000 50 rpm. Note: Do not shift the transmission at the stall conditions when the engine speed is above low idle rpm.
To prevent the transmission oil from getting too hot, do not keep the torque converter at full stall for more than 30 seconds.If transmission oil becomes too hot, perform the procedure that follows to cool the oil.
Shift the transmission direction control switch to the NEUTRAL position. Operate the engine at 1200 rpm to 1500 rpm in order to cool the oil. Stall speeds that are low indicate that engine performance is not correct. Stall speeds that are high indicate that transmission performance is not correct or that the performance of the torque converter is not correct. High stall speeds could also indicate that the power setting of the engine is too high. If you must repeat the test, keep the transmission in neutral and wait for two minutes between tests.
