warning

As the Piezo-Injector operates under maximum DC 200V, there may be a risk of an electric shock caused by shorted control line etc. So when repairing the injector or its wiring, disconnect the battery negative (-) terminal from the battery and wait for about 30 seconds.

caution

●

Common Rail Fuel Injection System operates with extremely high pressure (approximately 1,600bar), so never perform any work on injection system with engine running or within 30 seconds after the engine stops.

●

Keep cleanly the parts and the working area.

●

Pay attention to a foreign substance.

●

Just before installing injector, tube or hose, remove the protect-cap attached on them.

●

Do not remove injector except for special case.

●

When installing Injector

- Wash the contact area of the injector and replace the O-ring with a new one.

- Spread oil on the injector O-ring.

- To protect damage caused by shock, vertically insert the injector into the cylinder head.

●

When installing High Pressure Fuel Pipe

- Do not use again the used high pressure fuel pipe.

- Install the flange nut correctly.

Disconnect the injector return line (B).

note

Before connecting the injector return line or after disconnecting the injector return line, check that the plug bush was completely raised from the plug. Otherwise fuel will leak around the injector’s nipple because of broken plug.

note

[DISCONNECTION-INJECTOR RETURN LINE]

Pull the plug bush upward with the plug grip pressed.

Seize the return line on both sides of the plug, and then disconnect the plug upward from the injector nipple.

[CONNECTION-INJECTOR RETURN LINE]

With the plug bush fully raised, vertically install the plug to the injector nipple until "Click" sound generates.

Press the plug bush downward until "Click" sound generates.
