Connect the wire harness bracket with the bolt.
INSTALL NO. 2 NOZZLE LEAKAGE PIPE ASSEMBLY
Install the No. 2 nozzle leakage pipe assembly with the 2 bolts.
Connect the No. 6 fuel hose to the No. 3 nozzle leakage pipe assembly and slide the clamp to secure the hoses.
Install the No. 4 fuel hose and No. 5 fuel hose to the No. 2 nozzle leakage pipe assembly, and slide the 4 clamps to secure the hose.
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 new No. 1 injection pipe clamp and No. 2 injection pipe clamp with the 2 bolts.
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)
