5. Install secondary timing chain and sprocket to one of the banks
(Right bank shown in the figure) as described below.
a. Align mating marks (golden links) on secondary timing chain
with those (punched marks) on the intake and exhaust sprock-
ets.
b. Align camshaft knock pins with the sprocket groove and hole.
IBecause camshaft sprocket mounting bolts are tightened in
step 7, perform manual tightening to the extent necessary to
keep camshaft knock pin from dislocating.
SEM432G
IMatching marks of the intake sprocket are on the back side of
the secondary sprockets. There are two types of the marks;
round and oval types, which should be used for right and left
banks respectively.
Right bank: Round
Left bank: Oval
SEM433G
IIt 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 sprocket teeth in advance
using paint.
SEM434G
6. Install secondary timing chain and sprocket to the other bank.
Install primary timing chain at the same time.
IInstallation of the secondary timing chain follows the procedure
described in step 5.
IInstall primary timing chain so that mating mark (punched) on
camshaft sprocket is aligned with that (yellow link) on the tim-
ing chain, and mating mark (notched) on crankshaft sprocket
is aligned with that on the timing chain, respectively.
IWhen it is difficult to align mating marks of the primary timing
chain with each sprocket, gradually turn the camshaft hexago-
nal head using a spanner so it is aligned with the mating mark.
IDuring alignment, be careful to prevent dislocation of mating
marks on the secondary timing chain.

16. Install CVTC cover.
a. Install O-rings at front timing chain case.
b. Install seal ring at CVTC covers.
c. Apply liquid gasket to CVTC covers.
Use genuine RTV silicone sealant Part No. 999MP-A7007 or
equivalent.
IBeing careful not to move the seal ring from the installation
groove, align the dowel pins on the chain case with the holes
to install the CVTC cover.

17. Install RH and LH rocker covers.
Rocker cover tightening procedure:
ITighten in numerical order as shown in the figure.
a. Tighten bolts 1 to 10 in that order to 6.9 to 8.8 N´m (0.7 to 0.9
kg-m, 61 to 78 in-lb).
b. Then tighten bolts 1 to 10 as indicated in figure to 6.9 to 8.8
N´m (0.7 to 0.9 kg-m, 61 to 78 in-lb).
18. Hang engine using the right and left side engine slingers with
a suitable hoist.
19. Set a suitable transmission jack under the suspension mem-
ber.
20. Remove right and left side engine mounting nuts.
21. Remove right and left side suspension member bolts.
22. Install aluminum oil pan. Refer to EM-18, ªInstallationº.

c. Again tighten by turning 60É to 66É, about the angle from one
hexagon bolt head corner to another.
26. Install camshaft position sensor (PHASE), crankshaft position
sensors (REF)/(POS) and CVTC sensors.
27. Reinstall removed parts in the reverse order of removal.
IWhen installing fuel tube and intake manifold collectors, refer
to EM-12, ªTIGHTENING PROCEDURESº.
IAfter starting engine, keep idling for three minutes. Then
rev engine up to 3,000 rpm under no load to purge air from
the high-pressure chamber of the chain tensioners. The
engine may produce a rattling noise. This indicates that
