CAUTION / NOTICE / HINT
Note
When replacing the injector assemblies (including exchanging the injector assemblies between the cylinders), common rail assembly, intake manifold or cylinder head, it is necessary to replace the injection pipes with new ones.
When replacing the supply pump assembly, common rail assembly, intake manifold or cylinder head, it is necessary to replace the fuel inlet pipe with a new one.
PROCEDURE
INSTALL NO. 1 SUPPLY PUMP DRIVE COUPLING
| *1 | Camshaft |
| *2 | No. 1 Supply Pump Drive Coupling |
Install the No. 1 supply pump drive coupling into the camshaft as shown in the illustration.
INSTALL SUPPLY PUMP ASSEMBLY
Note
When installing, clean the sealing surfaces of the fuel inlet pipe sub-assembly, supply pump assembly and common rail assembly.
Apply a light coat of engine oil to a new O-ring.
Install the O-ring to the supply pump assembly.
Temporarily install the supply pump assembly with the 3 bolts.
INSTALL FUEL INLET PIPE SUB-ASSEMBLY
| *a | Correct |
| *b | Incorrect |
Note
When replacing the supply pump assembly, the fuel inlet pipe sub-assembly must also be replaced.
Replace the fuel inlet pipe sub-assembly with a new one when the fuel inlet pipe sub-assembly has been removed and reinstalled more than 5 times.
Temporarily install the fuel inlet pipe sub-assembly onto the supply pump assembly and common rail assembly.
Note
Install the fuel inlet pipe sub-assembly and union nut vertically, not at a tilt.
Tighten the supply pump assembly with the 3 bolts.
Using a 17 mm union nut wrench, tighten the union nut on the common rail assembly side.
Note
Use the torque value compensation formula to calculate the torque value for use when a torque wrench is combined with a tool such as a union nut wrench.
Using a 17 mm union nut wrench, tighten the union nut on the supply pump assembly side while holding the supply pump assembly with a 17 mm wrench.
Note
Use the torque value compensation formula to calculate the torque value for use when a torque wrench is combined with a tool such as a union nut wrench.
Connect the fuel hose and slide the clip to secure it.
Connect the nozzle leakage pipe assembly and install a new retainer spring onto the supply pump assembly.
Connect the 2 connectors to the supply pump assembly.
| *a | Upper |
| *b | LH Side |
| *c | 90° |
Connect the No. 2 fuel hose and slide the clip to secure it.
Note
Engage the clip within the area shown in the illustration.
| *a | Upper |
| *b | Front |
| *c | 90° |
Connect the No. 1 fuel hose and slide the clip to secure it.
Note
Engage the clip within the area shown in the illustration.
