CAUTION / NOTICE / HINT
Note
When replacing an injector (including interchanging injectors between cylinders) or common rail, replace the corresponding injection pipes with new ones.
When fuel lines are disconnected, air may enter the fuel lines, leading to engine starting trouble. Therefore, perform forced regeneration and bleed the air from the fuel lines Click here.
PROCEDURE
INSTALL FUEL INJECTOR LH
Note
Be sure to install the injector, holder clamp and bolt to their original positions.
Before installing the injector, check for carbon, foreign matter, etc. on the seal surfaces of the cylinder head and injector. If there is foreign matter, remove it before installing the injector.
Install 4 new injection nozzle seats to the cylinder head sub-assembly.
| *1 | Fuel Injector Seal |
Install 4 new fuel injector seals to each fuel injector as shown in the illustration.
| *1 | O-Ring |
Apply a light coat of clean engine oil to 4 new O-rings.
Install the O-rings to each fuel injector as shown in the illustration.
Insert the 4 injectors into the cylinder head sub-assembly.
Note
Insert the fuel injector until it touches the nozzle seat surface.
After installing the fuel injector to the cylinder head sub-assembly, the O-ring may prevent the injector from fully seating. If so, pull out the fuel injector and reinstall it.
Always return a fuel injector to the same place it was removed from.
For a fuel injector that has been replaced with a new fuel injector, register the injector compensation code Click here.
Temporarily install 4 new washers, 4 nozzle holder clamps and 4 new nozzle holder seals with the 4 clamp bolts.
| *1 | Washer |
| *2 | Nozzle Holder Clamp |
| *3 | Nozzle Holder Seal |
Note
The fork portion of the nozzle holder clamp must be set on the fuel injector.
Before tightening the bolts, check that the nozzle holder clamp is set properly.
To tighten the clamp bolts, first tighten them by hand until they cannot be turned further. Then, tighten the bolts to the specified torque in a later step.
When tightening the bolts, be careful not to tilt the bolt and clamp.
Do not reuse the washer.
| *1 | Nozzle Holder Clamp |
Temporarily install the common rail LH with the 2 bolts.
Temporarily install 4 new injection pipes to the common rail and fuel injector.
Check the nozzle leakage pipe. Check there are no scratches or dents on the union seal surfaces. If scratches or dents are present, replace the nozzle leakage pipe.
Temporarily install the No. 2 leakage pipe and 4 new gaskets with the 4 injector hollow screws and 2 bolts.
