ward 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 retard
angle side (to the right direction).
(c) Check that there is no clearance between the gear's fringe and the camshaft.
(d) Tighten the fringe bolt with the camshaft timing gear fixed. Torque: 54 N

(e) Check that the camshaft timing gear can move to the re-
tard angle side (to the right direction), and is locked at the
most retarded position.
18. INSTALL CAMSHAFT
(a) Turn the crankshaft pulley, and align its groove with timing mark 0 of the timing chain cover.
(b) Install the timing chain on the camshaft timing gear, with
the painted links aligned with the timing marks on the

(i) Tie the timing chain with a string as shown in the illustra- tion.
NOTICE:
Be careful not to drop anything inside the timing chain cov-
er.
15. INSPECT CAMSHAFT TIMING GEAR ASSY
(a) Check the lock of camshaft timing gear.
(1) Clamp the camshaft in a vice, and confirm the cam-shaft timing gear is locked.
NOTICE:
Be careful not to damage the camshaft.
(b) Release lock pin. (1) Cover 4 oil paths of the cam journal with vinyl tapeas shown in the illustration.
HINT:
The one of the 2 glooves on the cam journal is for retards (up-
per) and the rest is for advances (lower). Each groove has the
2 oil paths. Plug one of the oil paths for each groove with rubber
pieces before wrapping the cam journal with the tape. (2) Punctuate the tape for the advance oil path and for
the retard oil path in the opposite side from the ad-
vance as shown in the illustration.
(3) Put air pressure into two broken paths (the advance side path and the retard side path) with about 150
kPa {1.5 kgf
cm}.
CAUTION:
Cover the pathes with shop rag to avoid oil splashing.
