2.3.6. Injector and high pressure connector
z Be careful not to put any foreign
objects inside the injector and
high pressure connector when
performing disassembly
maintenance.
z O-rings and cooper washers
should be replaced with new one,
when reassembling the engine.
z Spray oil before assembling O-
Ring parts.
z Check the model number of the replacing part first before assembly.
2.3.7. Common rail system

in the “Common Rail” fuel injection system. The injection pressure is generated
independent of engine speed and injected fuel quantity stored in the ECU.
