FUEL PUMP(for High Pressure) INSTALLATION

PROCEDURE


  1. TEMPORARILY INSTALL FUEL PUMP ASSEMBLY


    1. B0072VXC04
      *1 Camshaft
      *2 Fuel Pump Assembly
      *3 Fuel Pump Lifter Assembly
      *a OK
      *b NG
      *c Oil Collection Area

      Turn the crankshaft pulley until the flat of the camshaft faces the fuel pump lifter assembly.

      Tech Tips

      This prevents the camshaft nose from pushing up the fuel pump lifter assembly when installing the fuel pump assembly.

    2. Pour 30 cc (1.8 cu. in) of engine oil into the oil collection area.

    3. B0072Q5C04
      *1 Cylinder Head Cover Sub-assembly
      *2 Pump Housing
      *3 Fuel Pump Spacer Gasket
      *a Pump Drive Cam (Engine Oil Application Point)
      *b Pump Lifter (Engine Oil Application Point)

      Apply engine oil to the pump drive cam and fuel pump lifter assembly.

    4. Install a new fuel pump spacer gasket to the cylinder head cover sub-assembly.

    5. B0076QJC05
      *a Fuel Pump Lifter Assembly (Engine Oil Application Area)
      *b Fuel Pump Lifter Housing (Engine Oil Application Area)
      *c Stopper Key
      *d Key Groove

      Apply engine oil to the inside of the fuel pump lifter housing and the outside of the fuel pump lifter assembly.

    6. Set the fuel pump lifter assembly on the fuel pump lifter housing as shown in the illustration.

      Note

      Align the stopper key of the fuel pump lifter assembly with the key groove of the fuel pump lifter housing.

    7. Apply engine oil to a new O-ring and install it to the fuel pump assembly.

      Note

      Do not damage the O-ring.

    8. B0075MBC05
      *1 Fuel Pump Assembly
      *2 Fuel Pump Lifter Guide

      Set the fuel pump lifter guide and fuel pump assembly on the cylinder head cover sub-assembly as shown in the illustration.

    9. Temporarily install the fuel pump assembly with the 2 bolts, leaving some allowance for left and right movement.

  2. TEMPORARILY INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY

    Note

    Do not damage the seals of the union nuts of the No. 1 fuel pipe sub-assembly.


    1. Temporarily install the No. 1 fuel pipe sub-assembly to the fuel delivery pipe RH and tighten the union nut by hand.

    2. Temporarily install the No. 1 fuel pipe sub-assembly to the fuel pump assembly and tighten the union nut by hand.

  3. INSTALL FUEL PUMP ASSEMBLY

    Tech Tips

    Perform "Inspection After Repair" after replacing the fuel pump assembly.



    1. Tighten the 2 bolts.

      Torque:
      26 N*m  { 265 kgf*cm, 19 ft.*lbf }

    2. Connect the fuel pump assembly connector.

  4. INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY


    1. B0072R8C01
      *a 17 mm Union Nut Wrench
      *b Torque Wrench Fulcrum Length

      Using a 17 mm union nut wrench, tighten the union nut on the fuel pump assembly side of the No. 1 fuel pipe sub-assembly.

      Torque:
      Specified tightening torque
      35 N*m  { 357 kgf*cm, 26 ft.*lbf }

      Note

      Do not adjust the torque in the loosening direction.

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

      • When using a 17 mm union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 30 N*m (306 kgf*cm, 22 ft.*lbf)

    2. Using a 17 mm union nut wrench, tighten the union nut on the fuel delivery pipe RH side of the No. 1 fuel pipe sub-assembly.

      Torque:
      Specified tightening torque
      35 N*m  { 357 kgf*cm, 26 ft.*lbf }

      Note

      Do not adjust the torque in the loosening direction.

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
