plug is cool enough to touch with your bare hands.
Release the pressure in the hydraulic system (page 14-7).
Drain the hydraulic oil from the hydraulic oil tank. The
capacity of the hydraulic oil tank is 80 liters (21.1 U.S.
Drain the oil from the gear reducer. The capacity of the
gear reducer is 4 liters (1.0 U.S. gal).

motor (2). Cap and plug immediately.
Attach a lifting strap and hoist to drum propel motor (2)
as shown. Remove two bolts (3), and remove drum
propel motor (2) and the O-ring seal from the drum gear
reducer. The weight of the drum propel motor is 18 kg
(40 lb). Check the O-ring for wear or damage and
