13. REMOVE CAMSHAFT TIMING GEAR ASSY

13. REMOVE CAMSHAFT TIMING GEAR ASSY

  1. Fix the No. 1 camshaft with a vise, and make sure that the camshaft timing gear does not rotate.
  2. Cover all the paths with vinyl tape except the advanced side path shown in the illustration.

c. Using an air gun, apply about 150 kPA (1.5kgf/cm), 21 psi)

c. Using an air gun, apply about 150 kPA (1.5kgf/cm), 21 psi) of air pressure to the port on the advanced angle side.

CAUTION: Some oil spraying will occur. Contain the spray with a shop rag.

HINT: This operation releases the lock pin for the extreme retarded angle lock.

d. Under the condition above, check that the camshaft timing gear can be turned by hand to the advanced angle side (counterclokΩise), the direction of the arrow in the illustration.

Standard: Must turn

HINT: The camshaft timing gear will turn to the advanced angle side without applying foce by hand depending on the force of the air pressure applied. Also, if applying pressure to the oil path is difficult as a result of air leakage from the port, the lock−pin may be difficult to release.

e. Remove the fringe bolt from the camshaft timing gear.

e. Remove the fringe bolt from the camshaft timing gear.

NOTICE:

  • Be sure not to remove the other 4 bolts.

  • If planning to reuse the camshaft timing gear assembly, release the straight pin lock first, and then install the gear.

14. INSTALL CAMSHAFT TIMING GEAR ASSY

14. INSTALL CAMSHAFT TIMING GEAR ASSY

  1. Put the camshaft timing gear and the camshaft together with the straight pin and key groove.
  2. Turn the camshaft timing gear (as shown in the illustration) while pushing it lightly against the camshaft. Push further at the position where the pin gets into the groove.

NOTICE: Be sure not to turn the camshaft timing gear to the retarded angle side (to the right direction).

  1. Check that there is no clearance between the gears fringe and the camshaft.
  2. Tighten the fringe bolt with the camshaft timing gear fixed.

    Torque: 54 Nm (551 kgfcm, 40 ftlbf)

  3. Check that the camshaft timing gear can move to the retarded angle side (to the right direction) and is locked at the extrene retard angleed position.
