37. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY

(a) Inspect the lock of the camshaft timing gear.

(b) After cleaning and degreasing the VVT oil hole on the intake side of the No. 1 camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.

NOTICE:
Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.

(c) Prick a hole in the tape covering the oil hole as shown in the illustration (Procedure A).

(d) Apply approximately 150 kPa (1.5 kgf/cm2, 22 psi) of air pressure to the hole pricked in procedure A to release the lock pin.





NOTICE:
* If air leaks out, reattach adhesive tape.
* Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.

(e) Forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise).

HINT
Depending on the air pressure applied, the camshaft timing gear assembly may turn in the advance direction without assistance by hand.

(f) Turn the camshaft timing gear assembly within its movable range (26.5 to 28.5°) 2 or 3 times without turning it to the most retarded position. Make sure that the camshaft timing gear assembly turns smoothly.





(g) Remove the adhesive tape from the No. 1 camshaft bearing cap.

38. INSPECT CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

(a) Check the lock of the camshaft timing exhaust gear.

(b) After cleaning and degreasing the VVT oil hole on the exhaust side of the No. 1 camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.

NOTICE:
Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.

(c) Prick a hole in the tape covering the oil hole as shown in the illustration (Procedure B).

(d) Apply approximately 200 kPa (2.0 kgf/cm2, 28 psi) of air pressure to the hole pricked in procedure B to release the lock pin.





NOTICE:
* If air leaks out, reattach adhesive tape.
* Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.

(e) Using a screwdriver with its tip wrapped with tape, forcibly turn the camshaft timing exhaust gear in the retard direction (clockwise).

NOTICE:
* Be sure to keep the camshaft timing exhaust gear in the retard direction using a screwdriver. If the gear is released, it will return to the most advanced position automatically due to force from the spring.
* Do not damage the camshaft timing exhaust gear.

(f) Using a screwdriver with its tip wrapped with tape, turn the camshaft timing exhaust gear within its movable range (19 to 21°) 2 or 3 times without turning it to the most advanced position. Make sure that the camshaft timing exhaust gear turns smoothly.





(g) Remove the adhesive tape from the No. 1 camshaft bearing cap.

39. REMOVE CAMSHAFT TIMING GEAR ASSEMBLY

(a) Remove the flange bolt while holding the hexagonal portion of the camshaft, and then remove the camshaft timing gear assembly.

NOTICE:
* Before removing the camshaft timing gear, make sure that the lock pin has been released.
* Be sure not to remove the other 4 bolts.
* Keep the camshaft timing gear assembly horizontal while removing it from the camshaft.

40. REMOVE CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

(a) Remove the flange bolt while holding the hexagonal portion of the camshaft, and then remove the camshaft timing exhaust gear assembly.

NOTICE:
* Be sure not to remove the other 4 bolts.
* Keep the camshaft timing exhaust gear assembly horizontal while removing it from the camshaft.

41. REMOVE CAMSHAFT BEARING CAP

(a) Uniformly loosen and remove the 5 bearing cap bolts in the sequence shown in the illustration.





(b) Uniformly loosen and remove the 15 bearing cap bolts in the sequence shown in the illustration.





NOTICE:
Uniformly loosen the bolts while keeping the camshaft level.

(c) Remove the 5 bearing caps.

HINT
Arrange the removed parts in the correct order.
