2. Install camshaft sprockets.
^
Install intake and exhaust camshaft sprocket by selectively using the groove of dowel pin according to the bank. (Common part used for both
banks.)
^
Lock the hexagonal part of camshaft in the same way as for removal, and tighten bolts.
3. Install crankshaft sprockets for both banks.
^
Install each crankshaft sprocket so that its flange side (the larger diameter side without teeth) faces in the direction as shown.
NOTE: The same parts are used but facing directions are different.
4. Install timing chains and associated parts.
^
Align the mating mark on each sprocket and the timing chain for installation.
CAUTION: Before installing chain tensioner, it is possible to change the position of mating mark on timing chain and each sprocket, after the
mating marks are aligned, keep them aligned by holding them by hand.
^
Install slack guides and tension guides onto correct side by checking with identification mark on surface.
^
Install chain tensioner with plunger locked in with stopper pin.
CAUTION:
^
Before and after the installation of chain tensioner, make sure that the mating mark on timing chain is not out of alignment.
^
After installing chain tensioner, remove the stopper pin to release tensioner. Make sure tensioner is released.
^
To avoid chain-link skipping of timing chain, never move crankshaft or camshafts until front cover is installed.
5. In the same way as for right bank install timing chain and associated parts on left side.
6. Install oil pump.
7. Install oil pump drive spacer as follows:
^
Install so that front mark on front edge of oil pump drive spacer faces the front of engine.
^
Insert oil pump drive spacer according to the directions of crankshaft key and the two flat surfaces of oil pump inner rotor
^
If the positional relationship does not allow the insertion, rotate oil pump inner rotor with a finger to allow the oil pump drive spacer.
