b. Install timing chain (secondary) and camshaft sprockets (INT and EXH).
^
Align the mating marks on timing chain (secondary) (gold link) with the ones on camshaft sprockets (INT and EXH) (punched), and install
them.
NOTE:
^
Mating marks for camshaft sprocket (INT) are on the back side of camshaft sprocket (secondary).
^
There are two types of mating mark, circle and oval types. They should be used for the right and left banks, respectively.
Right bank: Use circle type.
Left bank: Use oval type.
^
Align dowel pin and pin hole on camshafts with the groove and dowel pin on sprockets, and install them.
^
On the intake side, align pin hole on the small diameter side of the camshaft front end with dowel pin on the back side of camshaft
sprocket, and install them.
^
On the exhaust side, align dowel pin on camshaft front end with pin groove on camshaft sprocket, and install them. In case that positions of
each mating mark and each dowel pin are not fit on mating parts, make fine adjustment to the position holding the hexagonal portion on
camshaft with wrench or equivalent.
^
Mounting bolts for camshaft sprockets must be tightened in the next step. Tightening them by hand is enough to prevent the dislocation of
dowel pins.
^
It may be difficult to visually check the dislocation of mating marks during and after installation. To make the matching easier, make a
mating mark on the top of sprocket teeth and its extended line in advance with paint.
c. After confirming the mating marks are aligned, tighten camshaft sprocket mounting bolts.
^
Secure camshaft using wrench at the hexagonal portion to tighten mounting bolts.
d. Pull stopper pins out from timing chain tensioners (secondary).
6. Install tension guide.
7. Install timing chain (primary) as follows:
