Engine Replacement

Diesel Engine

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 Operating Manual or the
section Periodic Maintenance 8000YRM1774.
WARNING
Always disconnect the cables at the battery be-
fore you make repairs to the engine. Disconnect
the cable at the negative terminal first.
1. Remove overhead guard. See section Overhead
Guard Replacement for procedures.
2. Remove floor mast and floor plate.
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.
3. Let coolant cool to ambient temperature. Place a
drain pan with a capacity greater than the ca-
pacity of cooling system under radiator. Remove
radiator cap.
CAUTION
Disposal of lubricants and fluids must meed local
environmental regulations.
