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.

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.

Application Procedure”.) on both ends of arched area (loca-
tions where rear chain case is adjoined) as shown in the fig-
ure.
