Timing Chain Cover: Installation

  1. Make sure to remove the hardening sealant, foreign materials, oil, dust and moisture gathered in the liquid gasket sealing surface (cam carrier, cylinder head, cylinder block, lower crankcase). Then, spray the cleaner on the sealing surface and wipe off with a clean towel.
  2. Install the timing chain cover.
    1. Apply a sealant for liquid gasket to the interface between the cam carrier, cylinder head, cylinder block and lower crankcase.

      Bead width:  Ø 3.0 - 5.0 mm (0.11 - 0.19 in.)

      Sealant:  MS 721-40 AA or AA0

    2. The part must be assembled within 5 minutes after sealant was applied on the mounting surface of liquid gasket of timing chain cover.

      When applying the liquid gasket, apply it to the 1 mm position at the end of the chamfer inside the timing chain cover.

      Bead width:  Ø 3.0 - 5.0 mm (0.11 - 0.19 in.)

      Sealant:  MS 721-40 AA or AA0

    3. The dowel pins on the cylinder block and holes on the timing chain cover should be used as a reference in order to assemble the timing chain cover (A) to be in exact position.

      Tightening torque: 

      Bolt B: 9.8 - 11.7 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.6 lb.ft)

      Bolt C: 18.6 - 22.5 N.m (1.9 - 2.3 kgf.m, 13.7 - 16.6 lb.ft)

      NOTE:
      • The engine starting or pressure tests should not be performed within 30 minutes after the timing chain cover was assembled.
  3. Replace the front oil seal if necessary.

    (Refer to Timing System - "FRONT OIL SEAL ")

  4. Remove it by breaking the center of E-CVVT motor plug (A).

    NOTE:
    • Remove after 30 minutes of switching "OFF" the ignition to drain out the oil inside the E-CVVT motor plug.
    • Do not tilt the front of engine (timing chain cover side) downward as residual oil may flow out during E-CVVT motor plug removal.
    • If oil flows out during E-CVVT motor plug removal, wipe off immediately and block the motor shaft inlet with a clean towel.
  5. Clean the E-CVVT motor plug mounting surface (A) with oil cleaner.

    NOTE:
    • If the surface is not cleaned, E-CVVT motor plug may be separated due to diminished separation force from residual oil.
    • When spraying oil cleaner, block around the motor shaft inlet and rotor gap with a clean towel to prevent inflow of oil from flowing into the rotor gap.
  6. When reusing the E-CVVT cover, inspect the below items.
    1. If there is sign of leakage from inside the E-CVVT cover, replace it with a new one.
    2. Check the connector brush wear condition.

      Specification  : Over 5 mm (0.1969 in.)

      measurement is below specification, replace the E-CVVT cover with a new one.

    3. Check for damaged oil seal and replace any damaged E-CVVT cover with a new one.

    4. After inspecting E-CVVT, if no problem is found, replace the o-ring (A) with a new one.

  7. Install the E-CVVT cover.
    1. Apply engine oil to the oil seal lip (A).

      NOTE:
      • When applying oil, keep the connector brush (A) clean from foreign materials.

    2. Insert the SST (09243-C2000) into the E-CVVT motor shaft.

      NOTE:
      • Correctly mount SST onto the motor shaft.
    3. Slowly push the E-CVVT cover (A) until it is flushed with the timing chain cover surface.

      NOTE:
      • Installing the E-CVVT cover without SST may cause oil leakage inside the E-CVVT motor due to damaged or separated E-CVVT oil seal.
    4. Pre-tighten the bolts in the below sequence, and then remove the SST (09243-C2000).

      Tightening torque: 

      0.9 - 1.9 N.m (0.1 - 0.2 kgf.m, 0.7 - 1.4 lb.ft)

    5. Tighten the bolts to the specified torque in the sequence below.

      Tightening torque: 

      9.8 - 11.7 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.6 lb.ft)

  8. Install the E-CVVT plug.
    1. Insert the plug into the E-CVVT cover hole using SST (09243-C2000).

  9. Inspect the pressed depth of E-CVVT plug.
    1. By using a steel ruler, measure the distance from E-CVVT cover center boss to the end of motor shaft ((1)).
    2. By using a steel ruler, measure the distance from E-CVVT cover center boss to the end of E-CVVT plug ((2)).

    3. Calculate the pressed depth ((3)) of motor plug.

      If out of specification, reinstall after replacing the E-CVVT plug with a new one.

      Pressed depth: 

      (3) = (2) - (1)

      Specification: 

      1.1 - 2.1 mm (0.0433 - 0.0826 in.)

  10. Insert the E-CVVT cover plug so that the protrusion reach to E-CVVT cover groove correctly.

    NOTE:
    • Check how much protrude after installing the E-CVVT plug.
    • Be careful that the plug is not inserted inside E-CVVT cover beyond the regulated range.

  11. Install the variable force solenoid valve (VFS) (A).

    Tightening torque: 

    9.8 - 11.7 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.6 lb.ft)

    NOTE:
    • Do not reuse the variable force solenoid valve (VFS) if it is dropped.
    • When installing the Variable Force Solenoid Valve (VFS), pay attention to the following points.
      1. After replacing the variable force solenoid valve (VSF) O-ring (A) with a new one, apply engine oil to the new O-ring (A).
      2. Push the variable force solenoid valve (VFS) to the end of the timing chain cover mounting surface, and then pre-tighten the bolts.
      3. Tighten the variable force solenoid valve (VFS) with specified torque.
  12. Installation is in the reverse order of removal.
