Mount the injection pipe oil seal so that excessive force will not be
applied to the injection nozzle. (If the injection pipe oil seal and the
injection nozzle are out of position, oil leakage or improper assembly
of the injection pipe will result.)

While working, be careful not to make dirt and water enter parts.
Before mounting parts, make sure that there is no dirt on the
connection between them.
Air enters the fuel pipe in the process of mounting the pre fuel fil-
ter case. After mounting is completed, thoroughly purge air from
the fuel pipe.
MOUNTING THE INJECTOR AND THE INJECTION PIPE
Apply engine oil to a new O-ring and mount it to the injector. Then
temporarily fit the injector clamp and injector at the same time.
Apply engine oil to the O-ring. Use care not to get the O-ring
jammed when inserting it.
Note that if the O-ring is damaged, fuel will leak out and the
engine will fail to start to run.
Do not fix the injector clamp until the injection pipe is fit tempo-
rarily.
Slip a new injection pipe oil seal on the injector, and mount the plate
with the bolts (2 pcs.) that secured it.
Temporarily mount new injection pipes (6 pcs.) on the injector and the
common rail.
Do not fail to replace the injection pipes with new ones because
they are subjected to high pressure and may cause fuel leakage.
Fuel will leak out if the injection pipes are not properly con-
nected. Follow the procedure.
Fuel leakage will cause damage to the engine.
