Converter stall test is test of engine, torque converter, drivetrain, and brake system as a unit. Con-
verter output stalls with engine at full throttle. This test will indicate if engine and transmission perfor-
mance is acceptable under full load. Engine speed that is lower or higher than normal indicates engine
or transmission problems. When performance of engine is correct, but stall speed is not correct, prob-
lem is in converter or transmission.
Drive wheels must not turn during stall test. Place machine in position against solid object that will not
move when subjected to full thrust of machine. Engage parking brake. When tests are made, service
brakes must be applied.
Start engine (TM 5-3805-290-10). Make sure transmission oil is at normal operating temperature of 180 to 200°F (82 to
93°C). Cold transmission oil temperature will result in a lower stall rpm.
