Note
When replacing the parts in the following chart (A), replace the No. 1 injection pipe sub-assembly, No. 2 injection pipe sub-assembly and/or fuel inlet pipe sub-assembly with new ones.
| Replaced Parts (A) | Pipes Requiring New Replacement |
|
|
| Supply pump assembly | Fuel inlet pipe sub-assembly |
|
|
After removing the No. 1 injection pipe sub-assembly, No. 2 injection pipe sub-assembly and/or fuel inlet pipe sub-assembly, clean them with a brush and compressed air.
The injector assembly is a precision instrument. Do not use the injector assembly if it is struck or dropped.
Make sure foreign matter does not enter the fuel path.
INSTALL COMMON RAIL ASSEMBLY
Install the common rail assembly with the 2 nuts.
Connect the fuel pressure sensor connector to the common rail assembly.
Attach the wire harness clamp.
INSTALL NO. 4 FUEL HOSE
Connect the No. 4 fuel hose to the common rail assembly, and slide the clamp to secure it.
TEMPORARILY INSTALL NO. 1 AND NO. 2 INJECTION PIPE SUB-ASSEMBLY
Temporarily install the 2 No. 2 injection pipe sub-assemblies with the 4 union nuts.
Temporarily install the 2 No. 1 injection pipe sub-assemblies with the 4 union nuts.
TIGHTEN NO. 1 AND NO. 2 INJECTION PIPE SUB-ASSEMBLY
| *a | Torque Wrench Fulcrum Length |
Using SST, tighten the 8 union nuts of the No. 1 and No. 2 injection pipe sub-assemblies.
Tech Tips
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using SST (fulcrum length of 50 mm (1.97 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 31 N*m (316 kgf*cm, 23 ft.*lbf)
INSTALL FUEL INLET PIPE SUB-ASSEMBLY
Note
When replacing the fuel supply pump assembly, it is necessary to replace the fuel inlet pipe sub-assembly, No. 1 injection pipe clamp and No. 2 injection pipe clamp with a new one. Keep the fuel inlet pipe sub-assembly free of foreign matter.
Temporarily install the fuel inlet pipe sub-assembly.
Install a new No. 1 injection pipe clamp and No. 2 injection pipe clamp with the 2 bolts.
| *a | Torque Wrench Fulcrum Length |
Using SST, tighten the fuel inlet pipe sub-assembly union nut on the common rail side sub-assembly.
Tech Tips
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a union nut wrench (fulcrum length of 50 mm (1.97 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 31 N*m (316 kgf*cm, 23 ft.*lbf)
| *a | Torque Wrench Fulcrum Length |
Using a 19 mm union nut wrench, tighten the fuel inlet pipe sub-assembly union nut on the fuel supply pump assembly side.
Tech Tips
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 41 N*m (418 kgf*cm, 30 ft.*lbf)
INSTALL NO. 4 FUEL PIPE SUB-ASSEMBLY
Temporarily install the No. 4 fuel pipe sub-assembly and 2 new gaskets with the 2 union bolts and bolt.

INSTALL WIRING HARNESS CLAMP BRACKET
Install the wiring harness clamp bracket the cylinder head cover sub-assembly with the bolt.
Connect the pressure discharge valve connector to the common rail assembly.
INSTALL EGR COOLER ASSEMBLY
CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
