TORQUE CONVERTER STALL TEST

N OT E
Machines using quality fuel with transmissionoil at normal operating temperatures should have
engine stall speeds within the specified range. Refer to the factory test measurements to determine
the appropriate specification for the machine being serviced. If the machine being serviced is out-
side the range of engine stall speeds, the powertrain components should be inspected. Use the
component test specifications to determine the corrective action. These ranges of engine stall
speed should not be used to adjust the engine power of the machine. If engine output is suspect,
the engine should be tested on a dynamometer.
The torque converter stall test helps determineif the engine is producing the correct power out-
put. The torque converter stall test provides an engine speed for comparison with the torque con-
verter stall speed measured at the factory. The engine stall speed should be in the range shown.
The torque converter stall test helps determineif the engine is producing the correct power out-
put. This stall test is used in many diagnostic procedures.
The parking brake must be applied when the tess are performed. Ensure that the parking brakes
t
are fully operational before performing any tests.
The service brakes must be applied when the tests are performed. Ensure that the service brakes
are fully operational before performing any tests.
Ensure the transmission oil is at the normal op rating temperature of 167 to 220 F (75 to 105
e
C) before performing tests.
