29. REMOVE NO. 2 CHAIN VIBRATION DAMPER See: Engine Lubrication/Oil Pump/Service and Repair/Removal and Replacement/Removal
30. 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 the 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.
