Engine Replacement
REMOVE ENGINE ONLY
WARNING
The lift truck must be put on blocks for some
types of maintenance and repairs. The removal of
the following assemblies will cause large changes
in the center of gravity: mast, drive axle, engine
and transmission, and counterweight. When the
lift truck is put on blocks, put additional blocks in
the following positions to maintain stability:
• Before removing the mast and drive axle,
put blocks under the counterweight so the
lift truck cannot fall backward.
• Before removing the counterweight, put
blocks under the mast assembly so the lift
truck cannot fall forward.
The surface must be solid, even, and level when
the lift truck is put on blocks. Make sure that any
blocks used to support the lift truck are solid,
one-piece units. See the procedure How to Put Lift
Truck on Blocks in the Operating Manual or the
Periodic Maintenance section for your lift truck.
The engine can be removed with or without transmis-
sion. Follow procedures below to remove engine with-
out transmission. See Figure 23 or Figure 24.
WARNING
Always disconnect the cables at the battery be-
fore you make repairs to the engine. Disconnect
the cable at the negative terminal first.
WARNING
LPG can cause an explosion. DO NOT cause
sparks or permit flammable material near the LPG
system. LPG fuel systems can be disconnected
indoors only if the lift truck is at least 8 m (26 ft)
from any open flame, motor vehicles, electrical
equipments, or ignition source.
1. For lift trucks equipped with an LPG fuel system,
close shutoff valve on tank and run engine until all
fuel is gone and engine stops.
2. If lift truck is equipped with an LPG fuel tank,
swing tank to side. See one of the following Serv-
ice Manuals:

WARNING
DO NOT remove the radiator cap from the radiator
when the engine is hot. When the radiator cap is
removed, the pressure is released from the sys-
tem. If the system is hot, the steam and boiling
coolant can cause burns.
4. Let coolant cool to ambient temperature. Place a
drain pan with a capacity greater than capacity of
cooling system under radiator. Remove radiator
cap.
