removing the transmission from, and installing it to the

7.10.1 Engine Removal
1. Park the vehicle on a firm, level, surface. Level the
vehicle, ground the attachment, place the travel
select lever in the (N) NEUTRAL DETENT position,
engage the parking brake switch and shut off the
engine.
2. Secure accident prevention tags to the steering
wheel and ignition switch. (Refer to Section 1.5,
“Accident Prevention Tag Usage.”)
3. If the vehicle has dual batteries, disconnect both
negative battery cables (1 and 2) from both
batteries.
To access the lower battery (3), loosen the knob (4)
far enough so that the lip (5) on the upper battery box
clears the knob. Lift up the upper battery box (6) and
swing it out, so that the box clears the hydraulic tank
support bracket, to gain access to the lower negative
battery cable (1). Disconnect the lower negative
battery cable.
4. Remove the engine hood with the help of at least
one assistant. (Refer to Section 4.8.2, a. “Engine
Hood Removal.”)
5. Slowly turn the radiator cap (7), located near the
upper radiator hose, to the first stop and allow any
pressure to escape. Remove the radiator cap. Place
a hose (8) onto the drip leg of the petcock, located at
the base of the radiator to channel the drained
coolant into a container. Open the radiator
petcock (9) and allow the coolant to drain. Transfer
the coolant into a properly labeled container.
Dispose of properly. Close the radiator petcock (9)
when finished and remove the hose (8).
WARNING:
To avoid severe burns, DO
NOT attempt to remove the engine when the
engine, cooling system and hydraulic system
are hot. Wait until all parts and systems are
cool before proceeding.
