Secondary Timing ChainNJEM0093CAUTION:
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.
Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprockets, crankshaft pulley,
and camshaft brackets.
When removing the oil pans, oil pump assembly and tim-
ing chain from engine, first remove the crankshaft posi-
tion sensor (TDC sensor).
Be careful not to damage sensor edges.
Do not spill engine coolant on drive belts.
JEM120G
REMOVALNJEM0093S01For preparative work for removing/installing secondary timing
chain to remove/install fuel injection pump, refer to EC-25,
“Electronic control fuel injection pump”.
To prepare for removing/installing secondary timing chain to
remove/install camshaft, refer to EM-46, “CAMSHAFT”.
1. Drain engine oil.
2. Drain coolant by removing cylinder block drain plugs. Refer to
LC-43, “Changing Engine Coolant”.

3. Remove front chain case.
Move power steering fluid reservoir tank from the bracket.
Loosen fixing bolts in the 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.
SEM514G
CAUTION:
While front chain case is removed, cover openings to pre-
vent entry of foreign material into engine.
Do not remove two mass dampers on the back of cover.
SEM515G
4. 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 the crankshaft pulley.
When 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
injection pump sprocket may not be easy to see.
JEM124G
5. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with
a push pin.
JEM125G
b. Using a hexagon-head wrench (face to face: 5 mm, SST),
remove bolts to remove chain tensioner.

6. Remove timing chain slack guide.
Using a hexagon-head wrench (face to face: 6 mm, SST),
remove bolt to remove timing chain slack guide.
JEM127G
7. Remove timing chain tension guide.
8. Remove secondary timing chain.
Timing chain alone can be removed without removing sprock-
ets.
SEM885F
INSPECTIONNJEM0093S02Check for cracks and excessive wear at roller links. Replace
chain if necessary.
JEM128G
INSTALLATIONNJEM0093S031. Install secondary timing chain.
When installing, match the alignment marks on sprockets with
color coded alignment marks (colored links) on the chain.
2. Install timing chain tension guide.
The upper bolt has a longer shank than the lower bolt.

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, SST),
tighten bolts.
c. Pull out the push pin, etc. holding the plunger.
Check again that the alignment marks on the sprockets
and the colored alignment marks on the timing chain are
aligned.
SEM514G
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.
JEM129G
b. Apply specified liquid gasket (Refer to EM-3, “Liquid Gasket
Application Procedure”.) on both ends of arched area (loca-
tions where rear chain case is adjoined) as shown in the fig-
ure.
c. Install front chain case.
When installing, align dowel pin on oil pump case with the pin
hole.
JEM121G
Install 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.
