CAUTION:

After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.

When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting
surfaces with new engine oil.

Loosen fixing bolts in reverse order of that shown in the figure
and remove them.

Remove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:

While front chain case is removed, cover openings to
prevent entry of foreign material into engine.

Do not remove two mass dampers on the back of
cover.
5. Set the No. 1 piston to TDC on its compression stroke.

Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.

No position indicator is provided on crankshaft pulley.

When installing, color coded links on secondary timing
chain can be used as alignment marks. Marking may not
be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
pump sprocket may not be easy to see.
6. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.

a. Push the plunger of chain tensioner. While holding it with a push
pin, install chain tensioner.
b. Using the hexagon wrench (special service tool), tighten bolts.
c. Pull out the push pin, etc. holding the plunger.

Make sure again that the alignment marks on the sprock-
ets and the colored alignment marks on the timing chain
are aligned.
5. Install front chain case.

a. Install tension guide on the back surface of front chain case.

Hold front chain case vertically when installing. Tension guide
may come off if front chain case is tilted.
b. Apply a continuous bead of liquid gasket on both ends of arched
area (locations where rear chain case is adjoined) as shown in
the figure.
