lLoosen fixing bolts in the reverse order of that shown in the
figure and remove them.
lRemove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
lWhile front chain case is removed, cover openings to
prevent entry of foreign material into engine.
lDo not remove two mass dampers on the back of cover.
5. Set the No. 1 piston to TDC on its compression stroke.
lTurn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
showninthefigure.
lNo position indicator is provided on the crankshaft pul-
ley.
lWhen installing, color coded links on the secondary tim-
ing 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
supply 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.
b. Using a hexagon-head wrench [face to face: 5 mm, (0.20 in)
SST], remove bolts to remove chain tensioner.

INSTALLATION
1. Install secondary timing chain.
lWhen installing, match the alignment marks on sprockets with
color coded alignment marks (colored links) on the chain.
2. Install timing chain tension guide.
lThe upper bolt has a longer shank than the lower bolt.
3. Using a hexagon-head wrench [face to face: 6 mm (0.24 in),
SST], install timing chain slack guide.
4. Install chain tensioner.
a. Push the plunger of the chain tensioner. While holding it with a
push pin, install the chain tensioner.
b. Using a hexagon-head wrench [face to face: 5 mm (0.20 in),
SST], tighten bolts.
c. Pull out the push pin, etc. holding the plunger.
lCheck again that the alignment marks on the sprockets
and the colored alignment marks on the timing chain are
aligned.

"Precautions for Liquid Gasket".) on both ends of arched area
(locations where rear chain case is adjoined) as shown in the
figure.
c. Install front chain case.
lWhen installing, align dowel pin on oil pump case with the pin
hole.
lInstall No. 6, 10 and 11 bolts with the rubber washer to the
front chain case.
d. Tighten fixing bolts in the numerical order shown in the figure.
e. After tightening all the bolts, re-tighten in the same order.
