TIMING CHAIN
4. Install timing chains and related parts.
 Align the mating mark on each sprocket and timing chain for installation.NOTE:
Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for
that on each sprocket for alignment.
CAUTION:
For the above reason, after the mating marks ar e aligned, keep them aligned by holding them
with a hand.
 Install slack guides and tension guides onto correct si de by checking with identification mark on surface.
 Install chain tensioner with plunger fixed as described in its removal.
CAUTION:
 Before and after the installation of chain tens ioner, make sure that the mating mark on timing
chain is not out of alignment.
 After installing chain tensioner, remove stoppe r pin to release tensioner. Make sure tensioner
is released.
 To avoid chain-link skipping of timing chain, do not move crankshaft or camshafts until front
cover is installed.
5. Perform the same procedure as for right bank, install timing chain and related parts on left side.
6. Install oil pump. Refer to LU-29
.
7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank- shaft 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 spacer.
b. After confirming that the position of each part is in correct condi- tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.  Apply new engine oil to both oil seal lip and dust seal lip.
