REMOVAL SERVICE POINT

<<A>> TIMING CHAIN CASE ASSEMBLY REMOVAL

1.If the timing chain case is hard to detach, insert a screwdriver into the shown rib to lever off it.

INSTALLATION SERVICE POINTS

>>A<< O-RING/TIMING CHAIN CASE ASSEMBLY/GASKET INSTALLATION
1.
caution
  • Be sure to remove the sealant remaining in the mounting hole and gap between parts.
  • After degreasing with degreasing agent, check that there is no oil on the surface where the sealant is applied.
  • After degreasing with degreasing agent, never touch the degreased area with fingers.
Remove sealant from the timing chain case assembly and the timing chain case assembly mounting surface of the cylinder block and the cylinder head, and degrease the surface where the sealant is applied.
2.Remove all the sealant adhering to the gasket between the cylinder head and cylinder block (three-surface aligned part.) Then, degrease the surfaces.
3.As for the three-surface aligned part that is indicated in Step 2 above, the engine oil oozes from the cylinder head gasket. Thus, quickly apply the sealant to it after degreasing.
Specified sealant: ThreeBond 1217G or equivalent
4.

Apply the sealant without any gap to the mating surface of timing chain case assembly as shown in the figure.
Specified sealant: ThreeBond 1217G or equivalent
note Install the timing chain case assembly immediately after applying sealant.

5.
caution
  • When installing the timing chain case assembly, make sure that the O-ring is fitted into the groove securely.
  • If the sealant contacts any other part during installation of the timing chain case assembly, apply sealant again before installing the timing chain case assembly.
Align the holes on the timing chain case with the dowel pins on the cylinder block. Then install the timing chain case. To do this, check the O-rings do not fall off or are not seated improperly.

6.
caution After the installation, until a sufficient period of time (one hour or more) elapses, do not apply the oil or water to the sealant application area or start the engine.
Install the timing chain case assembly mounting bolts and gasket to the installation positions shown in the figure, and tighten them to the specified torque.
Tightening torque:

    A: 11 ± 3 N·m
    B: 21 ± 3 N·m

>>B<< OIL PUMP DRIVE SHAFT INSTALLATION

1.After wiping off the dirt on the oil pump drive shaft as shown in the figure using a rag, degrease the area.
note Degrease them to prevent drop in the friction coefficient of the pressed area, which is caused by oil adhesion.
2.Install the oil pump drive shaft with the straight side facing the crankshaft side.
