• Attach the rubber nozzle narrowed to the top of the air gun to
prevent air leakage from the oil hole. Securely apply the air
pressure to the oil hole (A).
CAUTION:
• There are other oil holes in the side grooves. Never use the incorrect oil holes.
• Be sure not to damage the oil path with the tip of the air
gun.
• Wipe all the oil off the air gun to prevent oil from being
blown all over along with the air, and the area around the
air gun should be wiped wi th a rag when applying air
pressure. Eye protection should be worn as needed.
NOTE:
The air pressure is used to move the lock pin into the disengage position.
c. Hold the camshaft sprocket (INT) with hands, and then apply the power counterclockwise/clockwise alter-
natively.
• Finally rotate the sprocket of the camshaft sprocket (INT) counterclockwise [the direction shown by the
arrow ( )].
• Perform the work while applying the air pressure to the oil hole.
• If the lock pin is not released by hands, tap the camshaft sprocket (INT) (1) lightly with a plastic hammer.
• If the camshaft sprocket (INT) (1) is not rotated counterclock- wise even if the above procedures are performed, check the
air pressure and the oil hole position.
d. While doing the above, once you hear a click (the sound of the internal lock pin disengaging) from inside the camshaft sprocket
(INT), start turning the camshaft sprocket (INT) in the counter-
clockwise direction in the most advanced angle position.
• Keep the air pressure on.
• If there is no click, as soon as the vane-side (camshaft side)starts moving independently of the sprocket, the lock pin has
become disengaged.
• Make sure that it is in the most advanced angle position by seeing if the stopper pin groove (A) and the stopper pin hole (B) are matched up as shown.
e. Complete the applying procedure of air pressu re and the holding procedure of camshaft (INT).
f. Insert the stopper pin (A) into the stopper pin holes in the cam- shaft sprocket (INT) (1) and lock in the most advanced angle
position.
CAUTION:
No load is exerted on the stop per pin (spring reaction, etc.).
Since it comes out easily, secure it with tape (B) to prevent
it from coming out.
NOTE:
The stopper pin shows one example of a hexagonal wrench for
2.5 mm (0.098 in) [length of inserted section: approximately 15
mm (0.59 in)].

INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
Fluids and Lubricants".
