GENERAL
5. TORQUE CONVERTER INTERNAL LEAKAGE TEST (Refer to Fig. 7B.3)
NOTE: The following oil leakage check should be performed with the engine running at full throttle
and oil at operating temperature. To obtain operating temperature, shift to third forward with the
foot brake applied until the temperature gauge pointer reaches the high side. Then shift to neutral
until the temperature gauge pointer stops. Repeat this procedure until the moment that the gauge
pointer, on dropping, stops at the green zone.
1. Shift the drive train control lever to the NEUTRAL and move the drive train lock lever to ON
position. Turn the electrical master switch to the OFF position and take out of the key from the
master switch to prevent accidental starting.
WARNING! Before working at the machine, be sure that the blade and ripper have
been lowered to the ground, engine is OFF, the drive train control lock lever is in
locked (ON) position and parking brake is set. The starting switch and the electrical
system master switch are turned OFF, keys are removed and the controls are
tagged to prevent inadvertent engine starting.
2. Remove the transmission case guard from the bottom of the machine.

3. Disconnect the torque converter drain hose end (3) from the engine flywheel housing (1). Cap
the hole of the hose end (3).
4. Take the disconnected hose end (3) out of the machine. Connect new hose to the flywheel
housing hole and put it in a separate container. Turn the electric master switch ON and start
