AD"ENGINE ASSEMBLY REMOVAL
After checking that all the cables, hoses, and harness
connectors have been disconnected, lift the engine with a
chain block slowly and remove the engine assembly located
at the upper engine room.
INSTALLATION SERVICE POINTS
"AAENGINE ASSEMBLY INSTALLATION
Install the engine assembly while checking that none of cables,
hoses, or harness connectors, etc. has been engaged.
"BAENGINE MOUNTING BRACKET AND STOPPER
ASSEMBLY INSTALLATION
1. Support the engine oil pan with a garage jack via a block
of wood cut adjusting the engine position and install the
engine mounting bracket and stopper assembly. Position
the engine mounting stopper so that a mark indicated
by an arrow can face the direction shown in the illustration.
2. Support engine with garage jack.
3. Remove the chain block and hold the engine assembly
with the special tool.(Tool used for removal of transmission
assembly)
"CAO-RING/FUEL HIGH PRESSURE HOSE
INSTALLATION
1. Apply small quantity of new engine oil on O-ring.
Caution
Do not let engine oil get into the delivery pipe.
2. Install the fuel high pressure pipe to the delivery pipe
rotating in both directions without damaging the O-ring
and check that it rotates smoothly.
3. In case of not rotating smoothly, remove the fuel high
pressure hose and insert it to the delivery pipe again
after checking damage of the O-ring since there is a
possibility of O-ring engagement.
4. Tighten fuel high pressure hose mounting bolt to the
specified torque.
Tightening Torque: 5.0±1.0 N·m
